CLASSIC & VERY EARLY FUKUIN ELECTRIC CO. / PIONEER HI-FI / STEREO SPEAKERS
PIONEER "TITAN IV"? SPEAKER
Circa 1960-61
for sale
Massive and VERY EARLY Pioneer 'Hi-Fi' speakers, direct from Japanese market. These appear to be original, factory built, Pioneer Titan IV speakers. The 1960 driver complement in these were typically offered in the US as 'kit' form (due to impracticality of shipping such voluminous cabinets from Japan) but according to their consignor, these were brought over by a GI on military transport, so economics was not an issue. He purchased them originally in Japan. These are among the first drivers branded 'Pioneer' from the original parent company Fukuin Electric Co. The company changed it's name to Pioneer in 1960 or 61. There are probably less than an 'handful' of these in the US (if that) and probably only a few dozen in the world. If you want the rarest of the rare Pioneer speakers, here you go. These things are MONSTROUS!
"Hey, Go Big or Go Home!"
Their huge drivers are both efficient and seem to be power capable (handled our Hafler P225 well, but as always, be careful with irreplaceable 'vintage speakers).
Our speaker tech has completely gone through and 'Certified' these.
He has completely disassembled them further, testing all drivers independently. No material issues found with any of the drivers. Each was 'swept' with the AF generator while removed. All drivers were re-installed with the addition of gasketing material to further seal and eliminate any ‘flange to baffle’ rattles and buzzes. Attenuators removed and cleaned for ‘static free’ operation. Gasketing added to the attenuator plates prior to re-installation as well. We also 'modernized' the input connectors (gasketing also added to their mounting plates). Gasketing also installed on rear panel, prior to re-installation. He also installed new, height adjustable, leveling, 'glide' feet. Entire speaker system then swept with our AF generator from 20-5,000 Hz and feeding them with the output from our Hafler P-225 Pro Power Amp, looking for any irregular vibrations / anomalies in either the drivers. driver mounting, crossovers or cabinet structure integrity.  Next we auditioned them with our standard, 'abusive' demo / testing CD's / cuts running the gamut from Dire Straits, 'Brothers in Arms', TLC 'Fan Mail', Allison Kraus and Union Station, Nickelback, a digital recording of a cathedral pipe organ, our 'Usher Speaker' demo CD (no not that Usher), 'Friday Night in San Francisco', with Al Dimeola, John McLaughlin and Paco DeLucia, Nickel Creek's Why Should the Fire Die, Jennifer Warnes, "Famous Blue Raincoat", and a few others, all digitally recorded and some 'DDD'.
Very 'large' sounding cabs. I did prefer them with an EQ, but I know you 'purists' would 'cringe' at that idea.
 Pioneer Titan IV Speaker Features include:
 
- 3-way, Bass-Reflex design
- 12" Pioneer PW-30C, Cast Aluminum frame, Low Frequency' Driver (woofer) w/ vented Voice Coil and AlNiCo magnet / motor.
- 6" Pioneer PM-16B midrange 16 Ohms & AlNiCo magnet / motor.
- 3" x 2.5" Pioneer PT-6, 16 Ohms Horn Tweeter w/ AlNiCo magnet / motor.
- Infinitely variable L-Pad for Tweeter attenuation
- Pioneer DN-7 2-Way / 3-Way Crossover
- 11.5" x 8" Tuned Port

Pioneer Titan IV Speaker Specifications:

System Design: 3-Way, Bass Reflex
Driver Compliment: PW-30C 12", Cast Frame Woofer, PM-16B midrange / Squawker, PT-6 Horn Tweeter & DN-7 Crossover.
Frequency Response: ~35-20,000Hz
 Nominal Impedance: 16Ω
 Cross-over frequency: Pioneer DN-7 500Hz & 4kHz @ 12dB / Oct
Power rating: likely 25-40 watts
 
The real wood, Mahogany veneer cabinets in INCREDIBLE shape, as are the original grills. They are virtually blemish / mark free and look like they could still be on the original show room floor. The cabinets have just had a fresh coat Howards 'Restore-a-Finish' and 'Feed-n-Wax' rubbed in to bring out their original luster. Again, our speaker tech has completely refurbished, tested and Certified these speakers performing the previously mentioned processes. Great speaker for a lower powered 'vintage' Hi-Fi system, or that low wattage or 'single ended' tube amplifier. They look, work and sound great! Cabinets measure 38" H x 27.25" W x 17.75" D and weighs a hefty 90 lbs each (due to their huge size once packed, the P,S & I on these to much of the lower 48 states of the US would run approx $450-$650. Locations such as North Eastern States, North Western Washington or Southern Fla would run more). Includes our standard 90 day limited warranty (excluding problems due to under / over powering.

VINTAGE PIONEER STEREO / HOME AUDIO SPEAKERS
PIONEER HPM-1500 / HPM1500
THE BIG ONES!
FROM THE PIONEER 'SPEC' ERA
(the HPM-1500's are the 'Military Market' / 'Euro / Asia' market version of the HPM-150)
  #...1201 & 0495
MIJ
  Circa mid 1977-79
SOLD 5/17/13
SHIPPING TO CALIFORNIA
  These were Pioneer's 'Flagship' / Top of the Line speaker for 1977-79. The Pioneer HPM-1500's. It's hard to expand on what's already been written out there about these speakers. Most fans of these know some version of their smaller brothers either the HPM-100, HPM-60 or the plethora of others, but the HPM-1500's are considerably more rare due to their large size and elevated original cost. They are capable of high volume levels while producing "pounding" & "tight" bass with great balance on the top and mid end.
Our speaker tech has completely gone through and 'Certified' these. Woofers were both re-foamed with fresh, new and 'correct' surrounds with perfect centering. We have completely tested all drivers. Both Mid and Top End attenuators were cleaned internally for static-free performance. All drivers were removed and tested individually. One of the 'Super Tweeters' (the really cool looking top one) was 'weaker' than the other, so we sourced and tested between 5 of them (Polymer, piezo driven 'Super Tweeters) to get the most efficient pair to replace. Gasketing material was added to all driver mounting flanges, prior to re-installation. We ‘added’ gasketing material the base and the lower cabinet, and between the woofer cab, and the 'mid-tweet' module, to further reduce any possibilities of vibration or acoustic anomalies. Felt feet were installed to the bottom plates. Cosmetically, the grills were cleaned & the cabinets 'real wood' Walnut veneer had a fresh coat of 'Feed-n-Wax' then buffed. The original 'Smoked Glass' top plates are chip, scratch and crack free. The cabs and grills (some fairly typical 'cat snags' to the black knit and a small, 'older repair ding' on the edge of the upper module - see above photos) are in great shape, especially for being around 33 years old. Next, as always they were tested with both recorded material, PN 20-20k and swept them with our AF generator from 1Hz-3kHz. Then came our standard, 'issue exposing' and on some levels, 'abusive' test recordings. These speakers are ready to go!
We auditioned this pair extensively and 'THEY DELIVERED' as expected, but additionally adding the 'gasketing' really 'tightened' up the cabinets and cleaned up the bass response. Also, the luxury of having enough 'Super Tweeters' to 'output match' their characteristics added enough 'top end' to rip your head off if you so choose. Following the above mentioned 'barrage' of test signals, our demo cuts ran the gamut from Dire Straits' "So Far Away" from their album 'Brothers in Arms' album, Donald Fagens, "I.G.Y." from the album "Night Fly", '24K Gold Edition of Jennifer Waren's "Famous Blue Raincoat', TLC's "Scrub" from their album 'Fan Mail' (did 'sub-bass' note @ 1'25" & 1'35" VERY WELL), Allison Kraus and Union Station's "Baby, Now That I've Found You" (this especially opens up with a Carver 'Sonic Holigraphy' unit on this album), Trapt's 'Headstrong', Don Williams' DDD version of 'Country Boy', Calvin Hampton's, "The Wedding March" from "Digital Pipes, The Splendor of the Organ" (was BIG as expected it should be) a digital recording of a cathedral pipe organ, Sheffield Labs' "Escape Clause" was 'crisp, solid and punchy', Most of the cuts from Michael Jacksons' 'Number Ones' such as "Bad" "Beat It", and "Smooth Criminal", were 'KILLER', Van Halens' '1984' cuts 'ROCKED', but especially "Hot for Teacher", a recording of 'Saint Patricks Cathedral Choir' (was very 'realistic' to listen to), and a few others, all digitally recorded and some 'DDD'.
Incredible power handling characteristics. They are able to handle "power" VERY well. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler 225 watt power amp (however, at only '9-Oclock' on the volume control, they were already INCREDIBLY LOUD!).
 Great 'balance' and reproductive detail. 'Solid', punchy and 'tight' low-end, with no 'mush'. We had a couple pair of HPM-1100's, and these have 'tighter' bass and certainly, way more 'top-end' (again, 'too much' can be 'rolled off' or filtered. Too 'Little'...well you can't 'fix' that).
These are in excellent condition as well.
 Great 'all around' speaker for that vintage stereo system. Efficient enough to make lower power units sound 'BIG', but tough enough to handle larger power amps.
 This is probably our 1st pair in 17 years.
  
Pioneer HPM-1500 Speakers Feature:
- 4-Way, 4-Driver, Bass Reflex cabinet design 
 - 15.75" / 40cm, Die-Cast-aluminum framed, "Ribbed",  Carbon-Fiber impregnated, pulp Woofers (not the later polymer / carbon fiber woofers that are so 'shatter prone')

KEF 105.4
'Reference Series'
HOME AUDIO SPEAKERS
 #... 1491A & B
 Circa 1980-84
MADE IN ENGLAND
for sale
KEF 105.4's, are easily contenders for some of the best speakers we've had for overall balance, volume / output and power handling capabilities. These have most everything I look for in a home audio speaker such as 'balance', detail, power handling, accuracy, punch and 'largeness of sound'. HUGE in both size and SONICS! Great for most genres of music. 3-Way / 4-Driver, pseudo 'acoustic suspension' cabinet design (actually what they KEF calls "Nuevo Bass Loading Technique". Just a great 'all-around' speaker for home audio listening or recording ‘studio monitor’ use. Just as happy with a medium-small size amp as they are with amps of larger size. A very interesting feature of these speakers is a 'sighting' lens / LED arrangement that allows you to rotate / tilt the Midrange / Tweeter units on either X or Y axis to perfectly 'aim' them at a 'critical' listening area.
 Our speaker tech has completely gone through and 'Certified' these. Speakers were entirely disassembled. Crossover components and circuit boards were 'damped' to 'proactively' reduce any possible 'sympathetic' component vibrations. He also 're-attached' the 'anti-resonance' pads in the upper driver housings. He also installed fresh felt bumpers under the mid / high housings. Our tech has completely tested all drivers, then re-assembled with their original and adequate gasketing material under all driver frames to further reduce any possibilities of vibration or acoustic anomalies, and tested with recorded material, PN and swept them with our AF generator from 20-3kHz. Following, of course our normal barrage of 'pink noise' and an AF sweep from 3k down to 20Hz, our demo cuts ran the gamut from Dire Straits, 'Brothers in Arms', TLC 'Fan Mail', Allison Kraus and Union Station, Nickelback, a digital recording of a cathedral pipe organ, our 'Usher Speaker' demo CD (no not that Usher), 'Friday Night in San Francisco', with Al Dimeola, John McLaughlin and Paco DeLucia, Nickel Creek's Why Should the Fire Die, and a few others, all digitally recorded and some 'DDD'.
Incredible power handling characteristics. They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler 225 watt power amp.
Cabinets cleaned, then had a coat of Howards 'Restore-A-Finish' and 'Feed-n-Wax' rubbed into the 'real' teak wood veneer and are in great shape. Grills including grill frames and cloth in great condition as well with only very minor wear. All 8 original swivel castors in fine shape. Overall, the speakers look and perform great!
 
 KEF 105.4 SPEAKER FEATURES:

 - 3-Way, 4-Driver Acoustic Suspension / Infinite Baffle Bass cabinet design 
 - Dual 8" / 200mm, 'Bextrene' cone woofer, with non-deteriorating Butyl rubber surround.
- 4.25" / 110mm Polymer Midrange in separate, individual polymer housing
- 1" / 25mm KEF 'T33'  Fabric Dome Tweeter in separate, individual polymer housing
- Very well designed and built, '19-Element' internal  cross-over   

- Overpowering protection built-in
- LED 'Optimum Listening Area' indicator'
- Speaker input connectors are heavy duty, 3-Way, binding posts
- 'Matched Pair' Paired to spec within 0.5 dB of each other on all aspects, per KEF 105.4 brochure.
 
 KEF 105.4 SPECIFICATIONS:
 Frequency Response: 55-20,000Hz +/-2dB at 2m on design axis or 30-30,000Hz -10dB
 Efficiency: ~86 dB 1w @ 1m
 Maximum Output 'program material': ~108 dB 1w @ 1m
 Nominal Impedance: 8Ω each
 Cross-over frequencies: @ 150, 400 & 2kHz
 Recommended Power Amp Rating: 40-200 watts per channel
Max Power Rating: 200 watts per channel of 'music / program' material
Protection: 'S-STOP" The system is protected against any continuous or intermittent fault conditions which produce input signals not greater than 70V peaks from DC to 50kHz
  
Again, we have completely tested all drivers at individually applicable frequencies with a sweep generator looking for any irregular anomalies in either the drivers or cabinet structure integrity. Very nice looking REAL 'Teak' wood, veneer cabinets. Cabinets and veneer overall in excellent shape and look great (wood under grills darker, than exposed wood due to age of finish and exposure to ambient light). Both grill frames and their cloth in fine shape with no breaks or tears.
These have most everything we look for in a home audio speaker such as 'balance', detail, power handling, accuracy, punch and 'largeness of sound'. Bass response was 'deeper' than about 70% of the speakers we audition, based on the ability to reproduce one of our very difficult 'test cuts'. They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler power amp.
Also, again, these look great having the above mentioned work and are ready to go!

W/ 12" DUAL CONCENTRIC
HPD/A/315/8 DRIVERS
STEREO SPEAKERS
 Circa 1977-81
MADE IN ENGLAND
 for sale
BIG in SIZE and HUGE in SONICS! These are one of the most incredible sounding speakers we have had. These have most everything I look for in a home audio speaker such as 'balance', detail, power handling, accuracy, punch and 'largeness of sound'. These are in excellent condition as well. Plenty of top end that can be filtered / tailored to your tastes with built-in, user definable crossover points and attenuator or external EQ / tone control. Huge, DEEP low-end that still stays incredibly tight (shakes the concrete floor in our demo room). They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler power amp. Among the top performers of the many speakers we have auditioned over the years. 
Our speaker tech has completely gone through and 'Certified' these. Both woofers, have had their foam surrounds replaced in the not too far off past, and were professionally done with quality materials. We removed the crossover / attenuator modules and cleaned a 4 controls for static free sonics. We also removed the driver bells, and added gasketing to their mating surfaces to reduce any possible sonic anomalies, as well as adding gasketing material to the driver mounting flange.

The real Tweak wood veneer, cabinets in great shape and have been given a coat of Howards 'Restore a Finish' then buffed w/ 'Feed-n-Wax'. The built-in bases have been 'spruced' up cosmetically as well and new, feet installed. The original black knit grills are in great shape with both original 'Tannoy' logos / badges intact. The original frames are structurally sound with no issues.  

We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator from 20-5,000Hz and feeding them with the output from our Hafler P-225 Pro Power Amp. Then further auditioned with a myriad of our difficult to reproduce 'test' CD's.
 
  Features: 
  - 2-Way, Concentric Compression horn driver compliment, Bass Reflex cabinet design, internally braced to reduce spurious resonances
- Perfect 'On-Axis' potential
- 12" Woofer, Tannoy HPD/315/A/8 'Dual Concentric' 'Gold' Driver w/ Ticonal-G magnet (a trade-name for Alnico), Girdacoustic reinforced cone and 50mm / 2" Voice Coil.

  Sensitivity: 89dB @ 1W / 1m
  System impedance: 8 ohm nom
 Recommended Amplifier rating: 20 watts minimum,  w/ 60 watts as a recommended maximum safe power input (a more powerful amp may be utilized if precautions are taken to avoid conditions such as 'turn-on' surges and amplifier clipping which may result in momentary power peaks greatly in excess of specified ratings)


In the tradition of Tannoys, these are built using the 'concentric / coaxial' woofer / tweeter design. About as 'on-axis' as you can get.
Again, these are among the best 'all around' sounding speakers, I have auditioned in a VERY LONG TIME! From the original Tannoy Cheviot brochure, "Twin ducted ports give a bass response that out of all proportion to it's modest size". They are capable of excelling with about any genre of music.

ESB

 HOME AUDIO SPEAKERS
#...7400 / 7401
  Circa 1984-86
MADE IN ITALY
  for sale
 There aren't many ESB's in North America, as they were imported in limited quantities from Italy, where they comprised approx 25% of the speaker market!
 ESB (ELECTROACOUSTIC SYSTEMS BUILDING)  They are an impressive speaker in design, build quality, construction and sonics. Their detailed and balanced sonics are accomplished via a couple of design characteristics. One is the 'coupled' Midrange and Tweeter design. The other would be the a radical modification of Horizontal and Vertical alignment. From a 1984 review,
"A key element in the design of all the Series 7 speakers is what ESB calls DSR (for "distributed spectrum radiation"). which is intended to maintain accurate, consistent stereo imaging over a wide listening area. Vertically, this is achieved first by building the mid- and hi-frequency drivers on a single mounting flange, minimizing the distance (and therefore the interference) between them, so that they act as nearly as possible like a single point source... The method ESB uses to stabilize the image horizontally is a refinement of a familiar technique. 'Toeing in' a pair of speakers so that their forward radiating axis cross slightly in front of the listening position usually broadens the area in which you can sit without the stereo image collapsing into the speaker nearer to you."

These are great performing speakers for most any genre of music. We extensively tested them with our barrage of material. They were very balanced and handled power well. Probably not a speaker for every week party's, but for a great 'large' sound, you'll love them. These are in beautiful physical condition as well.
  Features include:
  
- 3-Way, Acoustic Suspension / Infinite Baffle cabinet design
- Asymmetrical / Mirror image cabinets w/ angled high-frequency baffle
- 10" Woofer with fresh foam surrounds (were re-foamed prior to their arrival to our shop. The tech utilized 'Cerwin-Vega' surrounds, which are 'red' in color, then 'blackened' them, with questionable success. Sound and perform fine, but noticeable cosmetically)
- 2" Hemispherical 'coated' silk dome midrange w/ heavy duty motor 'coupled' to tweeter plate
- 1" Hemispherical 'coated' silk dome tweeter w/ heavy duty motor 'coupled' to mid plate
- Heavy duty, Banana / Binding Post speaker input terminals
- Externally located, independent, glass fuse protection for all 3 drivers
 - Incredibly well built crossover.
 - Heavy build, 'acoustically solid' cabinets
  
  Specifications:
  
System Design:  3-Way, Infinite Baffle / Acoustic Suspension
Frequency Response:  45Hz - 20kHz ±3dB
  Crossover points: 600Hz & 6,000Hz
  Sensitivity: 87dB @ 1W, 1m
  System impedance: 6 ohm nom / 5 ohms min.
 Recommended Amplifier rating: 40 watts minimum, and were originally tested when current with 300Hz bursts at 500 watts

Our speaker tech has completely gone through and 'Certified' these. The surrounds were recently replaced with 'Cerwin Vega' 'Red' foam, that was 'stained' black, prior to arriving to us. We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator from 20-5,000Hz and feeding them with the output from our Hafler P-225 Pro Power Amp. Then further auditioned with a myriad of our difficult to reproduce 'test' CD's.

With the exception of one missing logo, the original black knit grills are in great shape and the original frames are structurally sound.
Again, these are great looking and sounding speakers and would be happy coupled with most any medium to large receiver / amp.

VINTAGE & CLASSIC STEREO SPEAKERS
BOSE 601 ORIGINAL SERIES
 DIRECT / REFLECTING
 STEREO SPEAKERS
#...0765 & 2604
Made in USA
 Circa 1977
for sale
 In our opinion, the 601 series, was probably the best overall sounding of the "Direct / Reflecting" speakers Bose ever designed. I have had them all, as far as the 'classic' models go, 301's, 501's, 601's  and yes, plenty of Bose 901's. I sold for a Bose dealer thru most of the '80's at the consumer level and 'Pro' line thru much of the '90's. I currently own 4 pair of 901's (original series, series II, series III and series V and I like the 'original series' the best for a number of reasons), and two pair of their "pro" series 800 / 802 II's now as well. While interesting in design, none of them are anything I would want to spend much time listening to except the 601's (and maybe the 301's as "back ground" music. Sorry if I'm offending you Bose fans, but you need to "get out of the house more often"). While working for Bose dealers thru the Eighties, I and most folks I have ever known that sold audio, usually considered the 601's a "pleasant exception" to the typical "Bose Sound". The 601's, have great balance and power / frequency handling characteristics.
(Side note; The 601 series II and III's are equally 'decent' sounding, HOWEVER they are a 'nightmare' to pack adequately for safe shipment. So much of a nightmare, that unless you have the ORIGINAL packaging I don't recommend it! The tweeters in the series II & III protrude out of the top of the cabinet and have to be protected in such a way that none of their packaging can be allowed to touch them in transit. If it does it is likely that the top grill frames will be destroyed. That either requires the grills and all the top components to be removed, packed and shipped separately and then re-installed upon arrival (probably not practical), or as we did on the last pair of series II's we had, custom and very expensive packaging designed so that nothing could touch the top of the speakers, even if dropped on their tops. This is NOT typically going to be something that very many packers are going to be capable of. Due to the amount of requests we get for replacement grills and tweeter mounts, I am confident that most that are shipped by 'individual' sellers or packed by folks inexperienced in packing Bose 601 Series II's and III's are damaged or destroyed. We have a few thousand dollars worth of packing materials and 15+ years of experience and it took us 6 'man hours' to pack the last pair of series II's! The Original series do NOT have these issues as the sides panels of the cabinets come all the way to the top.)
 
Our speaker tech has completely gone through and 'Certified' these. These have been completely gone through, including having the foam surrounds replaced on all 4 woofers. All tweeters in perfect working order. We also removed the lower aluminum trim that was attached with staples and reattached w/ adhesive foam to eliminate vibration. The tweeters mounts were also tightened to eliminate any acoustic anomalies. The speakers were cleaned inside and out. New driver gasketing installed to improve factory seals. Our speaker tech also re-covered the grills in black knit, as opposed to the arguably 'ugly' tweed / burlap material they orginally came with. The top panels have a very gradual, upward 'arch' to them (see photo above, right). The grills were re-attached utilizing Velcro pads, and not the original 'nails', to facilitate removal. Beautiful, real walnut wood veneer cabinets give a fresh rub down w/ lemon oil.
 Features include:
 
 - Pseudo 3-4-way, Bass-Reflex 6-Driver cabinet design
- Dual 8" Woofer Design (one front firing and one up firing)
 -4x 3" sealed frame, cone Tweeters Reflecting front and back
 -2.75" Tuned Port for extended low frequency range and response
 -Nominal Impedance 8 ohms
 - 2kHz Cross Over Point
 - Binding post style wire connections
 -Bulb-type, 'Shock Absorber' protection for tweeters
- Selector for either 'Symmetrical' or 'Asymmetrical' tweeter array

BOSE 601 'ORIGINAL SERIES' Specifications / Specs:
 
Cabinet / Speaker design:  3 / 4 -Way / 6-Driver Bass Reflex via a 'Tuned Port'
Driver Complement: Dual 8-inch, steel frame woofers, Quad 3-inch steel frame cone tweeters firing in a direct / indirect combination
 Nominal Impedance: 8Ω
Recommended Minimum Power amplifier rating:  20 watts minimum - 200 watts maximum 
 
 Again if you're after a pair of "Vintage" Bose, the 601 are, in our opinion, the best sounding of the classic Bose designs. This pair especially excels on most classical and jazz styles. Again, the 'Real' wood Walnut grain veneer, cabinets in great shape as are the grills. The cabinet corners and edges all sharp and crisp. And remember, we have just replaced the foam surrounds on all 4 woofers, for trouble free service. Following the above work, we completely tested them with both recorded material, PN 20-20k and swept them with our AF generator from 20-20,000 Hz (actually all 4 woofers were independently swept after re-foaming and prior to re-installation as well the entire speaker once re-assembled) and feeding them with the output from our Hafler P-225 Pro Power Amp, looking for any vibrations or other anomalies. We then further auditioned with a myriad of our difficult to reproduce 'test' CD's. Entire cabinet has been frequency swept while being powered by our Hafler test amp. They sounded great! This is the first pair we have had in 15 years of having the web site (actually two pair came from the same owner, but I am keeping one pair for myself to add to my collection).  Cabinets measure 25.5" H x 15" W x 13" D and weigh 36 lbs each. Includes our standard 90 day limited warranty (excluding problems due to under / over powering)

CERWIN VEGA
"EVICTION NOTICE"
STEREO SPEAKERS
AT-100  AT100
 Circa 1990'S
"MILITARY / EURO-AISA" MARKET SPEAKERS
 for sale
HUGE in both size and SONICS! If you want to GET LOUD, then these Cerwin Vega, AT-100's are the ticket. 3-Way / 4-Driver, Bass Reflex cabinet design. If you want a speaker to GET LOUD and not worry about, these are about as beefy as you're going to get without going to a pro-audio, SR speaker and still get Hi-Fi detail. Plenty of top end that can be filtered / tailored to your tastes with built-in attenuator or external EQ / tone control. Also DEEP low-end due to rear porting, that still stays incredibly tight (shakes the concrete floor in our demo room). They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler power amp. I sold 'Pro-Audio' for years, and these would 'hold a candle' to much of those models of speakers for power handling characteristics, but with 'Hi-Fi' sound quality / detail. Among the top performers of the many speakers we have auditioned over the years. 
Our speaker tech has completely gone through and 'Certified' these. Both woofers, just had fresh and 'official' new foam surrounds installed for trouble-free service. Attenuators cleaned for static free sonics. We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator.
  Features: 
   
- 15" Heavy-Duty, Cast Frame Low Frequency Driver (Woofer) with fresh and official Cerwin Vega foam surrounds installed
- 2x5" Midranges
- 1" High-Compression, Radial Horn Tweeter w/ 'Microcell Polymer Dome'
- "Real" internal cross-over, not just a couple of "caps" on the mids and tweets
- Dual 'Hi' and 'Mid' frequency attenuators, using resistors, not failure prone Ni-Chrome wire, for custom tailoring sound to your tastes and listening room
 - 5" Rear Port for extended low end
- 3-Way Banana / Binding Post connectors
  
CERWIN VEGA AT-100 SPECIFICATIONS:

System: 3-Way / 4-Driver, Bass Reflex
Frequency Response: 28-28,000Hz +/- 3dB
Efficiency: 102dB 1w @ 1m
Nominal Impedance: 4Ω
Cross-over frequencies: 400Hz & 3kHz
LF Driver VC Size: 2.05"
Recommended Minimum Power Amplifier: 5 watts
Recommended MAX Power rating: 250 watts RMS with 400 watt peaks
Maximum Output Level, Pair at 3m w/ Full Power: 127dB
 
  Very nice looking wood grain, black vinyl wrap cabinets. Only cosmetic issues are some minor 'dings' to the edges and one to a rear corner (see photos above). Both grill frames and their knit cloth in fine shape with no breaks, or serious snags. Again woofers just had fresh, new and official, Cerwin Vega foam surround installed for trouble-free service. We also installed new gaskets on the mid horns. All drivers are in perfect condition, work and sound fine! Tested for all frequencies, 20-5kHz with a sweep generator with no anomalies.
Speakers look and sound GREAT! HUGE, accurate and loud sound, but also very efficient at lower powers due to their 102dB rating! If you're looking for a great performing speaker at medium to higher volume applications with that big 'Wall-O-Sound', or want to throw parties every weekend you will not be disappointed with these speakers. Each measures 36.5" tall x 19" wide x 17.5" deep and weighs 75 lbs unpacked. Includes our standard 90 day limited speaker warranty ( & excluding problems due to under / over powering)

BOSTON ACOUSTIC SPEAKERS
BOSTON ACOUSTIC A200
Circa 1979-'82
(these are actually internally dated 1981)
Made in USA
for sale
One of the rarer of the classic Boston Acoustic models. The Boston Acoustic A200 stereo speakers. The "200" was the original Boston Speaker when they had 1 (one) model of speaker. Great speaker for detail, balance and that big "wall-o-sound" presence.
Features include:

- 3-way, Bass-Reflex design
-10" Low Frequency Driver (woofer)
-4" "Ferrofluid" Cooled Mid- Range in it's own, isolated enclosure to reduce dB robbing bass reflections
-1" Soft-dome, "Ferrofluid" Cooled Tweeter
- Rear located, Mid and Tweeter protection fuses

Specs:

Frequency Response: 38-20,000Hz +- 2.5dB
(36-25kHz @ - 3dB)
Efficiency: 90dB 1w @ 1m
Nominal Impedance: 8Ω nominal / 5.5Ω minimum
Cross-over frequencies: at 450Hz & 3kHz
Recommended Power amplifier rating: 20-250 watts

Our speaker tech has completely gone through and 'Certified' these. He completely tested all drivers. He replaced the 'crushed' original foam gasketing material with new sealant to reduce any possibilities of vibration or acoustic anomalies. He improved the grill 'sandwich' construction to eliminate vibrations and sonic anomalies. The previous owner replaced the original 'skids' with some that are a bit 'beefier'. Felt feet were installed to the bottom plates. Next, as always they were tested with both recorded material, PN 20-20k and swept them with our AF generator from 1Hz-3kHz. Then came our standard, 'abusive' test recordings. Cosmetically, the grills were cleaned & the cabinets 'real wood' Walnut veneer had a fresh coat of 'Feed-n-Wax' then buffed. The cabs and grills are in great shape. Only cosmetic issue (if you can call it an issue) is slight discoloration around the dust caps on the woofer cones from the solvent reaction with the original glue during the 're-foaming' process. Many speakers will demonstrate the same discoloration to the cones. Cosmetics only, and does not affect performance. (See photos above) These speakers are ready to go!
We auditioned this pair extensively and were VERY surprised at their performance. Following the above mentioned 'barrage', our demo cuts ran the gamut from Dire Straits' "So Far Away" from their album 'Brothers in Arms', Donald Fagens, "I.G.Y." from the album "Night Fly", '24K Gold Edition of Jennifer Waren's "Famous Blue Raincoat', TLC's "Scrub" from their album 'Fan Mail' (did 'sub-bass' note @ 1'25" & 1'35" SO SOLIDLY & PROMINENTLY THAT IT SHOOK OUR CONCRETE FLOOR, Allison Kraus and Union Station's Baby, Now That I've Found You", Trapt's 'Headstrong', Don Williams' DDD version of 'Country Boy', Calvin Hampton's, "The Wedding March" from "Digital Pipes, The Splendor of the Organ" a digital recording of a cathedral pipe organ, and a few others, all digitally recorded and some 'DDD'.
Very good power handling characteristics. They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler 225 watt power amp (however, at only '9-Oclock' on the volume control, they were already INCREDIBLY LOUD!).
While these speakers are physically large, it is not without reason. Their expansive baffle board serves to reduce any "out of phase" reflections / wave anomalies from neighboring surfaces. This way the speaker can "control" it's sonic results, instead of having it's environment as the major contributor. Secondly, the 'extreme separation' between the woofer and the 'mid-tweeter' section really helps to 'open up' recordings. Prevalent on many recordings such as on Allison Krause's "Baby, Now That I've Found You" to name just one, Thirdly, the tall stature of the A200  puts the tweeter more on plane with your ears, instead of your knees.

The real Walnut wood, veneer cabinets are great shape, as are the original black knit grills. Grill frames perfect with not broken or repaired parts. Both woofer surrounds just replaced with new foam for years of trouble-free service. Great speaker for up to mid volume levels. Again, these are more "detail" oriented speakers not "Power Pounding Party" speakers. If that's what you're looking for then don't buy these. These are "definitive" classic Boston speakers.
I spent an inordinate amount of time auditioning these speakers. I tried about every genre of music, including most of the selections listed on our 'Demo Cuts' page but here are some notes I made on their post restoration 'check sheet',

 "TLC "shook the concrete floor", Jen Waren "Famous Blue Raincoat" very natural, tweeter height really makes for great separation and no 'boxy-ness', choir recordings with Carvers 'Sonic Holography' are amazing, 'brash symphonic' pieces are HUGELY reproduced and amazing to listen too,  Flute and Piano are natural and realistic,  Tyrell Allen and Friends, "Electric Jazz Ensemble" was spectacular,  most of the 'Tutti!' CD was BIG AND IN YOUR FACE!  peakers really added a 'third dimension' to Allison Krause's "Baby, Now that I've Found You", especially with carvers 'Sonic Holography' engaged.
Pipe organ was a bit 'contained'. Most of 'Sheffield Drive' and John Pattucci's CDs were fabulous. Not a great speaker for most of 'Michael Jacksons "Number Ones". Great speaker for jazz and big band. A bit 'smeared' on Nickelback at higher volumes, however 'Trapt' recording 'ROCKED'! with lots of solid punch even at fairly high volume levels, Donald Fagens I.G.Y. perfect 'as expected'. Horn sections and piano sounds VERY NATURAL. Saxophone very realistic. Upright bass natural. Percussion 'Live!!!'. For some reason they seem to overall outperform my personal pair (don't know why, but need to re-evaluate mine)"

If you're looking for "true" wide frequency response, balance and detail then these may be the speaker for you (great for most all types of recordings; R&R, POP, RAP, Jazz and new-country, acoustic guitar recordings & classical / symphonic / string music. Very accurate, detailed sound!!! (Note: the close-up of the wood side in the collage photo above, is spot on as far as the hue / color of the actual finish. It's normally very difficult to show the actual color of speakers in photos). Cabinets measure 41.5" H x 21" W x 6.5" D  and weighs a hefty 65 lbs each. Includes our standard 90 day limited warranty (excluding problems due to under / over powering).

 "TIME WINDOW / 1A"
 STEREO SPEAKERS
 #...9780 & 9792
 CIRCA 1985-94
 MADE IN THE USA
 for sale
 One of most famous of the late '80's thru the mid '90's "audiophile" level stereo speakers. The DCM "Time Window / T-1A" 'Hybrid Transmission Line' speaker. I worked at a DCM dealer for a few years while these were current. We generally sold the lesser "Time Frame 350" models, simply due to the lower price of the "Frames". Most folks only dreamt of the "Windows". I have heard Time Windows on many different amps including Crown DC-300a's, McIntosh MC-30's and 75's, Missions, GAS "Son of Amp-zilla's", just about all the Carvers, Hafler DH-500's, NAD's and many others. Rarely disappointing. I am currently running my personal pair on a Hafler 225. For placement, Time Window's generally like to be along an un-cluttered wall, but these '1A's' are very 'forgiving' and placement is not so critical. While I am not much of a fan of speaking of "critical listening" when it comes to home theater applications, these also work well as "front channel" speakers, but coupling them with most "Class-D", "gutless", modern home theater receivers / amps would be a sacrilege (sorry just had to get that out). Great speaker for detail & balance. These have been completely tested and put through exhaustive paces on our test system. All drivers in great shape and cabinets are structurally sound. One additional 'pro' about this model / pair is that they don't use the 'open cell' foam that is always in some state of deterioration. They use a heavy, black speaker grill knit. The only cosmetic issue is that there's a small hole in the top of one grill and one logo is missing (see above photos). Both just had a fresh coat of lemon oil to the solid, oak wood top and bottom plates.
 
 Features include:
 
 - 2-way, 4-Driver, Ported, Hybrid Transmission Line design
 - Elliptically shaped cabinet to reduce bass nodes / anomalies
 -Dual, 6.5" Low Frequency Drivers (woofer) arranged asymmetrically with non-deteriorating Butyl Rubber suspension (no foam to worry about years down the road)
 -Dual, .75" Philips Tweeters
 - Real Wood tops and bottom plates
 
DCM "TIME WINDOW / T1A SPECIFICATIONS:

 Frequency Response: 30-20kHz
 Efficiency: 91dB 1w @ 1m
 Nominal Impedance: 8 Ohms nominal  / 5 Ohms minimum
  Cross-over frequencies: at 2.8kHz
 Dispersion: 180 horizontal x 60 vertical
 Recommended Power amplifier rating: 10 watts with a max peak of 200 watts
 
 "Specifications do not tell the whole story, listening does. The Time Windows due to their configuration can be literally tuned to any room. That is due to their shape. This was a brilliantly executed design that has remained faithful all these years." *
 
Great speaker for up to mid-high volume levels. Again, these are more "detail" oriented speakers not "Power Pounding Party" speakers. If that's what you're looking for then don't buy these.
 These are "high definition" speakers (actually more than the previous 2 pair of Time Windows we've had, they do ROCK. Very loud, with good power handling and HUGE volume). If you're looking for "true" wide frequency response, balance and detail then these may be the speaker for you (great for most all types of recordings; R&R, POP, RAP, Jazz and new-country, acoustic guitar recordings & classical / symphonic / string music.

 VINTAGE PIONEER STEREO SPEAKERS
PIONEER CS-63 / CS63
HUGE, LOUD CLASSICS!
#...0095
Circa early 1970
for sale
This model was the "Flag-Ship" of Pioneers' famous 'CS' line for this time period. These were the 'Big Brother' to the somewhat more common CS-99, and are great speakers in all aspects. This is the 'first' version of the 63's utilizing a multi-layer 'cloth' grill, which was switched mid-year to wood lattice (cloth does not 'rattle' like the wood lattice grill with it's multitude of small metal clips). You couldn't ask for better frequency response as these are rated 20Hz-22kHz! Huge 'Wall-Of-Sound' and very efficient. Probably the most efficient speaker Pioneer ever made at 99dB! Great for most power range amps / receivers, large or small and especially smaller Class A and Single-ended tube outputs (due to their increased efficiency).
Our speaker tech has completely gone through and 'Certified' these. We have completely tested all drivers. Both Mid and Top End attenuators had their contacts burnished and were cleaned internally for static-free performance. We ‘added’ gasketing material to the rear cabinet panel to reduce any possibilities of vibration or acoustic anomalies. Felt feet were installed to the bottom plates. Next, as always they were tested with both recorded material, PN 20-20k and swept them with our AF generator from 1Hz-3kHz. Then came our standard, 'abusive' test recordings. Cosmetically, the grills were cleaned & the cabinets 'real wood' Walnut veneer had a fresh coat of 'Feed-n-Wax' then buffed. The cabs and grills are in great shape, especially for being around 40 years old. These speakers are ready to go!
We auditioned this pair extensively and were VERY surprised at their performance. Following the above mentioned 'barrage', our demo cuts ran the gamut from Dire Straits' "So Far Away" from their album 'Brothers in Arms', Donald Fagens, "I.G.Y." from the album "Night Fly", '24K Gold Edition of Jennifer Waren's "Famous Blue Raincoat', TLC's "Scrub" from their album 'Fan Mail' (did 'sub-bass' note @ 1'25" & 1'35" SO SOLIDLY & PROMINENTLY THAT IT SHOOK OUR CONCRETE FLOOR, Allison Kraus and Union Station's Baby, Now That I've Found You", Trapt's 'Headstrong', Don Williams' DDD version of 'Country Boy', Calvin Hampton's, "The Wedding March" from "Digital Pipes, The Splendor of the Organ" a digital recording of a cathedral pipe organ, and a few others, all digitally recorded and some 'DDD'.
Great power handling characteristics. They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler 225 watt power amp (however, at only '9-Oclock' on the volume control, they were already INCREDIBLY LOUD!).
 Great 'balance' and reproductive detail. 'Solid', punchy and 'tight' low-end, with no 'mush'. We have had a few pair of both CS-63's and the 'supposedly' "radically improved" CS-63DX's and in our opinion they should have 'left them alone'. They didn't need to be 'improved'. These are in excellent condition as well.
 Great 'all around' speaker for that vintage stereo system. Efficient enough to make lower power units sound 'BIG', but tough enough to handle larger power amps.
 This is probably our 4th pair in 15 years.
 They usually don't hang around long.
We have completely tested them with both recorded material and swept them with our AF generator. 
They feature:
  
- 4-Way / 4-Driver, "Infinite Baffle" cabinet design
- 15" Woofer with non-deteriorating cloth suspension and 'Vented' dust cap for greater efficiency
- 6.5" Mid with non-deteriorating cloth suspension and 'Vented' dust cap for greater efficiency
- 2"x4" Tweeter / "Squawker" with / Diffusion Phase Plug
- 3" Super-Tweeter
- "Real" Internal crossover
- All Pioneer built components
- 3-Position Mid and High Frequency level attenuators
- Spring-Loaded input terminals
- Beautiful original condition real wood Walnut veneer over, very heavy and well built, 'void free plywood' cabinets
  
  Specs are as follows:
 Impedance: 8 ohms
 Efficiency: 99dB! 1w @ 1m
 Frequency Response: 20Hz-22kHz, +/- 3 dB
 Cross-over frequencies: @ 770Hz, 3.3k & 12kHz
  Power Rating: 60 watts RMS
  
If you like the "Mid-70's Lattice" look with about the 'biggest' sound possible, then these would likely be great speakers for you! Again, the Real Walnut wood veneer cabinets are in excellent and beautiful shape. The original metal framed, cloth grills PERFECT! (With these speakers you can ignore the following note we normally attach to Pioneer speakers with 'Lattice' grills, "we recommend running Pioneer 'Lattice grill' speakers with the grills removed. They used small metal clips for decoration and structural integrity, at each junction of the grill lattice waves. These can be a source of extraneous noise at different frequencies. This recommendation would be applicable to any Pioneer 'CS' series speaker with 'real' wood, lattice grills.")
Again, we have completely gone through these and they're 'Ready to Rock'. Measure 28.5"h x 19"w x 13"d and weigh 63 lbs each unpacked. Includes our standard 90 day limited warranty ( excluding problems due to under / over powering).

CS-A700
12", 3-way, Full-Range or "Multi-Amp capable speaker system"
#....1786 / 2481
  Made in Japan
  Circa 1970-72'ish
for sale 
This model was one of the Pioneer "Flag-Ships" of the 'early' famous 'CS' line featuring 'FB' cones and NO foam surrounds to deteriorate on any of the drivers. Was not a 'heavily sold' speaker as the crossover was 'potentially' more complicated than most folks needed or understood. It allows 'multi-amp' / 'Tri-Amp' use, but also standard 'Full Range' use as well (which is what most if not all folks should and would use). (Bi-amping and Tri-amping is way beyond what most folks running 'consumer grade' gear needs to do, even as an experiment, but that's for another discussion and time). These speakers are in the same 'sonic vein' as the CS-77's and CS-88's. Decent efficiency and above average power handling characteristics. Balanced well across the board.
Features include:

- Pioneers "F.B." design driver cones deliver more rigidity and lightweight performance resulting in quicker response and better mid-end with less distortion
 - 30 cm / 12" "FB"  (Free-Beating, wool impregnated pulp) Woofer w/ Non-deteriorating cloth surround

  Recommended Power Rating: 60 watt max power rating

These speaker had our full attention and service. Many 'vintage' speakers featured attenuators to tailor the top and mid-range levels. While this can be accomplished using a variety of different component choices, they are always going to be a 'service point' and will need to be cleaned to achieve consistent sound. The controls on the CS-A700 (and a few others) speakers are VERY difficult to service. To service them, we completely removed the crossover / input panel, then dissect / remove the shaft / switch components from the switch body. Once disassembled, then all copper traces and contacts can be burnished and 're-sprung'. Once reassembled, they function perfectly. It's a very time consuming process, but the only way to insure any level of performance. Otherwise, you'll only hear the woofer.
Our speaker tech has completely gone through and 'Certified' these. We further completely tested all drivers and inspected the gasketing material under all driver frames, as well as the back panel to insure they can reduce any possibilities of vibration or acoustic anomalies, then tested with both recorded material, PN 20-20k and swept them with our AF generator from 20-20kHz. Speakers cleaned inside and out. Cabinets were spruced up with a fresh coat of lemon oil. With the exception of a 'plant water circle' on the top of one, they look great. All drivers work and sound fine! Tested for all frequencies with a sweep generator. Also features a 'True', 3-way cross-over for super clean response especially in the "low end".
Both look and sound GREAT! Huge, accurate and loud 'Wall-O-Sound'. Very efficient as well. Check the spec!
The speakers are 8 ohms and rated conservatively for 60 watts. If you are looking for a 'BIG' sounding, durable, classic 'lattice grill' speaker and / or you feel the need to 'Tri-Amp', this is it.
 Each measures 26" tall x 15" wide x 12.5" deep and weigh 38 lbs each unpacked. Includes our standard 90 day limited warranty ( excluding problems due to under / over powering).

 BOSE STEREO SPEAKERS
 501 Series IV
 #...8937R & 8937L
 DIRECT / REFLECTING
"Free Space Array"
  'Mirror Image / Matched Pair'
STEREO SPEAKERS
  Made in USA
  Circa 1984-93
  for sale
   One of the most famous speaker models ever made. The Bose 501's. These are the 4th generation, the "Series IV's". Features Bose's famous "Direct / Reflecting" cabinet design. Has front firing 10" woofer and two angled / side firing, "Reflecting" tweeters. Our speaker tech has completely gone through and 'Certified' these. These have been completely gone through, including having the foam surrounds replaced on the woofers (which is no easy task on this model due to tricky grill removal / reinstallation). The 501's are probably the most difficult of the Bose or any speaker to access the drivers as the grills are stapled on with brads). Another note on the Bose 501 and most Bose foam surrounds. It is a safe bet that there are NO Bose 501's out there that are over 15 years old (and most are) that do not need the foam replaced on the surrounds. Even if it looks good, if you can stick your finger through it, (and you will be able to) or it feels "sticky", it needs to be replaced. It won't last many songs (probably only part way thru the first one) at any decent volume if you don't.
 The difficulty in re-foaming 501's is that the grills are nailed on with about 30, well hidden brads and beyond the resource level of most people to deal with. Thus, when they test them briefly, they get some sound and sell them as "speakers work fine and as they should". WRONG!!! They all need new foam if it hasn't already been done in the past 15 years. Again, these, as with most of our speakers, have just had fresh, new foam installed on the drives if applicable. I just had to reiterate that due to all the mis-information out there, especially on the "on-line" auctions. We also checked the internal Tweeter protection lamps. All tweeters in perfect working order. All ready to play and enjoy
  Features include:
  
- 3-way, 3-Driver, Bass Reflex, "Direct-Reflecting" speaker design
- 10" Woofer
-2x 3" sealed frame, cone Tweeters in reflecting configuration with dual crossover points
- 2.75" Tuned Port for extended Low End response
- 'Spring Clip' style wire connections
- 'Shock Absorber' / Lamp tweeter protection
- Acoustic Suspension cabinet
  
 Specifications / Specs:
 
Cabinet / Speaker design:  3-Way / 3-Driver Bass Reflex via a 2.75" 'Tuned Port'
Driver Complement: One 10-inch, steel frame woofer, dual 3-inch steel frame cone tweeters firing in a direct / indirect combination
 Nominal Impedance: 8Ω
 Cross-over frequency: 1.5kHz Cross Over Point for lower freq tweeter and 2.5k for upper freq tweeter
Power rating: 115 IEC rating
 Recommended Power amplifier rating: 20 watts minimum to 230 watts max amplifier rating
 
  If you're a Bose fan, 501's are a great 'all around sounding' speaker. Great balance, solid handling of bass (improved bass over the earlist series as the series IV is a 'Bass Reflex' design), good top end detail and well suited for about every genre of music. Again if you're after a pair of "Vintage" Bose, the 501's are one of the most famous of their designs. These are in NEAR NEW cosmetic shape with the only issue being a missing logo from one of the grills. The top edge banding vinyl veneer all perfect. The cabinet corners and edges all sharp and crisp. Virtually no wear to the tops. The original grill frames solid and cloth in beautiful condition and required only minor cleaning. 
 And remember, we have just replaced the foam surrounds on all woofers, for trouble free service. Following the above work, we completely tested them with both recorded material, PN 20-20k and swept them with our AF generator from 20-5,000 Hz and feeding them with the output from our Hafler P-225 Pro Power Amp, looking for any vibrations or other anomalies. We then further auditioned with a myriad of our difficult to reproduce 'test' CD's. Entire cabinet has been frequency swept while being powered by our Hafler test amp. They sounded great! Given that the 'IV' series covers almost 10 YEARS it was obviously a successful, proven design! Cabinets measure 25" H x 16" W x 15" D  and weigh 42 lbs each. Comes with an emailed copy of the owners manual. Includes our standard 90 day limited warranty (excluding problems due to under / over powering)

KENWOOD
"EVICTION NOTICE"
SPEAKERS
         MV-7  MV7    
 Circa 1990'S
"MILITARY / EURO-AISA" MARKET SPEAKERS
 for sale
HUGE in both size and SONICS! If you want to GET LOUD, with 'SOLID' low end that hit's like a gunshot, then here you go. Kenwood MV-7, 'Military Market' speakers. 3-Way / 4-Driver, Bass Reflex cabinet design. If you want a speaker to GET LOUD and not worry about, these are about as beefy as you're going to get without going to a pro-audio, SR speaker and still get Hi-Fi detail. Plenty of top end with a lot of 'throw' (but still sound killer at shorter distances) and again, 'hard hitting' bass response. Nice, 'sharp' kick drum reproduction. They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler power amp. I sold 'Pro-Audio' for years, and these would 'hold a candle' to much of those models of speakers for power handling characteristics, but with 'Hi-Fi' sound quality / detail. Unfortunately these have been refinished by someone in the past with what appears to have been a #12 broom, so while they look decent at a distance, up close, they're not going to win any awards for finish quality. Cosmetics aside, these again are among the top performers of the many speakers we have auditioned over the years. 
We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator as well as the typical myriad of test material CD's we use here.
  Features: 
   
- 3-Way / 4-Driver, Bass Reflex Speaker system  
- 2x 12" Low Frequency Drivers (Woofers)
- 4x11.5" Midrange Horn
- 1"x4" High-Compression, Slot Horn Tweeter
- "Real" internal cross-over, not just a couple of "caps" on the mids and tweets
 - Dual 2.75" Ports for extended low end response
- 3-Way Banana / Binding Post connectors
  
Specs:

System: 3-Way / 4-Driver, Bass Reflex
Frequency Response: Great bass to plenty of top end
Efficiency: Very
Nominal Impedance: 8Ω
Cross-over frequencies: Where they should be
Recommended MAX Power rating: 550 watts peaks
Maximum Output Level, Pair at 3m w/ Full Power: ear-splitting!
 
Again, the main issue with these speakers is the 'bad refinish'. Both grill frames and their knit cloth in decent shape with no breaks, or serious snags. Our speaker tech has completely gone through and 'Certified' these. He also added isolation material to all the driver mounting flanges. All drivers are in perfect condition, work and sound fine! Tested for all frequencies, 20-20kHz with a sweep generator with no anomalies.
Speakers look and sound GREAT! HUGE, accurate and loud sound, but also very efficient at lower powers! If you're looking for a great performing speaker at medium to higher volume applications with that big 'Wall-O-Sound', or want to throw parties every weekend you will not be disappointed with these speakers (should install tweeter protection if you're really going to use these in 'semi-pro' applications, such as 'discotheque' volume levels regularly). Each measures 23.5" tall x 27" wide x 14.5" deep and weighs 54 lbs unpacked. Includes our standard 90 day limited speaker warranty ( & excluding problems due to under / over powering)

From an original Yamaha NS-75T ad;
"The 12" woofer is made from specially developed carbon fiber material. Lightweight, yet very rigid, carbon fiber has superior sonic clarity and low-end definition. Even under the increased dynamic range and high power demands of digital audio...Both the dome midrange and the dome tweeter are made from a unique titanium-carbide composition. The result is outstanding transient response, wide sonic dispersion, and three-dimensional, transparent imaging. So you hear all the live 'in-studio' or 'on-stage' sound compact discs were recorded with."

  Again, we have completely tested these w/ AF sweep, PN 20-20k and our standard barrage of test recordings on our studio, Hafler test power amp. These are great sounding speakers. Reminiscent of many of the more 'audiophile' boxes of the late 70's and early 80's by A/D/S, Polk, Mordaunt-Short, JBL, other Yamaha 'NS series, such as the NS-690, NS-200M, NS-500M or NS-1000M' and a few others. Great balance and definition. Bass notes solid and 'hit hard'. Handles power, very well. Again, great for home audio use or would also be equally at home in a project recording studio. Each measures 27" tall x 15" wide x 13" deep and weighs 48 lbs unpacked. Includes our 90 day warranty (excluding problems due to under / over powering)

SANSUI SP-2500 SP2500 
 #...4006-4029
 Circa 1974-76 (in US. As early as ’71 in Asia)
  for sale
Great sounding, classic Lattice grill Sansui SP-2500 speakers. The little brothers to the famous and elusive SP-5500's.
Our speaker tech has completely gone through and 'Certified' these. We have completely tested all drivers. All drivers were removed and reinstalled into cabinet with ‘added’ gasketing material under their frames to further reduce any possibilities of vibration or acoustic anomalies. The same operation was done to the rear cabinet panel and the 'Tweeter Cluster' plate. Both Mid and Top End attenuators had there contacts burnished and were cleaned internally. Next, as always they were tested with both recorded material, PN 20-20k and swept them with our AF generator from 20-3kHz. Then came our standard, 'abusive' test recordings. These speakers are ready to go!

We auditioned this pair well. Following the above mentioned 'barrage', our demo cuts ran the gamut from Dire Straits, 'Brothers in Arms', TLC 'Fan Mail', Allison Kraus and Union Station, Nickelback, a digital recording of a cathedral pipe organ, and a few others, all digitally recorded and some 'DDD'.
Great power handling characteristics. They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler 225 watt power amp. Great 'balance' and reproductive detail. 'Solid', punchy and 'tight' low-end, with no 'mush'. These are in excellent condition as well.
 Great 'all around' speaker for that vintage stereo system. Efficient enough to make lower power units sound 'BIG', but tough enough to handle larger power amps.
 This is probably our 14th pair in 15 years.
 They usually don't hang around long.
  Features:
   
 - 3-Way, 5-Speaker design. 
 - 12" Non-deteriorating Cloth surround Woofer

 - Dual 2.5" tuned ports for extending low end
 - Vented Woofer dust cap for increasing low end efficiency

 Tested for all frequencies with a sweep generator. All drivers work and sound fine! Cosmetically, the speakers are fabulous, with nothing much to mention that's out of sorts. Cabinets, Grills and overall finish, all excellent. Speakers look, perform and sound GREAT!

Again, our speaker tech has completely tested and Certified these speakers as stated above.  These speakers sound huge with deep, yet tight bass and crystal top-end. Easily one of the best, biggest sounding speakers Pioneer made next to the 'upper units' in the 'HPM' series.

They are in above average cosmetic shape. One of the cabinets has a 'faded' dark, water ring on the top (see photos above). The original Walnut wood veneer finish in great shape and just had a fresh rub of Howards 'Feed-n-Wax'. The original all wood, lattice grills in good condition with no breaks, chips or missing parts, just still a bit 'dusty' beyond what our time in cleaning would be worth to add to their price. Overall they look fine. Measure 25"h x 14.5"w x 12.5"d and weigh 45 lbs each unpacked. This is your chance to own a great piece of Pioneer audio history. Includes our standard 90 day limited warranty ( & excluding problems due to under / over powering)

 VINTAGE
 ADVENT "LEGACY" SPEAKERS
10" 2-WAY
#...7989 / 8075
Circa 1986-92
Made in USA
for sale
  A later version of the famous "The Advent Loudspeaker" speakers series, the Advent "Legacy's". Great looking and sounding 2-way speakers. Very accurate!!!
 Our speaker tech has completely gone through and 'Certified' these. Speakers were entirely disassembled. Woofer surrounds just replaced with new foam for trouble-free service. Our tech has completely tested all drivers, then re-assembled with their original and adequate gasketing material under all driver frames to further reduce any possibilities of vibration or acoustic anomalies, and tested with recorded material, PN and swept them with our AF generator from 20-3kHz. Following, of course our normal barrage of 'pink noise' and an AF sweep from 3k down to 20Hz, our demo cuts ran the gamut from Dire Straits, 'Brothers in Arms', Donald Fagen's 'I.G.Y.', TLC's 'Scrub' from the CD 'Fan Mail', (they did very well at reproducing the 'sub-bass' notes at 1'33" & again at 1'44"), Allison Kraus and Union Station, our 'Usher Speaker' demo CD (no, not that Usher), Nickel Creek's Why Should the Fire Die, and a few others, all digitally recorded and some 'DDD'.
Great power handling characteristics. They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler 225 watt power amp.
Cabinets cleaned, then had a coat of Howards 'Restore-A-Finish' and 'Feed-n-Wax' rubbed into the 'real' teak wood veneer and are in great shape with minimum normal wear (see above photos). Grills including grill frames and cloth in great condition as well with only very minor knit holes and a small 'postage stamp' size discoloration (see photos above). Grill frames 'break free' and all 8 locating pins in original 'intact' condition. Overall, the speakers look and perform great!
 
  Features include:
  
- 2-Way, Acoustic Suspension cabinet design
- 10" High Excursion, ribbed paper cone woofer with fresh foam suspension installed
- 1" Mylar, Soft-Dome Tweeter
 - "Real" internal crossover
 
 Specs:
 
 Frequency Response: 42Hz - 23kHz, +/- 3 dB
 Efficiency: 90dB 1w @ 1m
 Impedance (nominal): 6 ohms (minimum): 4 ohms
 Cross-over frequencies: at 2kHz
 Recommended Power amplifier rating: 20-100 watts
 
  Solid Oak top cap and bottom front plate make for a super quality look. Cabinets in great shape as are the original knit grill cloth. Very accurate speakers. 'Pin-point' accuracy. Great for really 'analyzing' a recording. Not 'fatiguing' to listen to for extended periods (something that's actually harder to find than you might think). These are among the best sounding of the vintage speaker models you will hear! Cabinets measures 28.5" high x 16" wide x 10" deep and weighs a heavy 43 lbs each. Includes our standard 90 day limited warranty (excluding problems due to under / over powering.)

VINTAGE EPI STEREO SPEAKERS
EPI MAGNUS A12 SPEAKERS (aka EPI MAGNUS A1200)
#...6113 & 6114
Circa 1985-86
MADE IN USA
 for sale
The 'Magnus' line, from EPI, hit the market in the mid '80's. They were designed with generally  larger woofers than had traditionally been offered in EPI's main line-up. These are the EPI, Magnus A12's (same speaker as the model known as the A1200)
Our speaker tech has completely gone through and 'Certified' these. We have completely tested all drivers. Surrounds on both woofers and both mids, just replaced with fresh, new foam for trouble-free service. Also, by design, these speakers had NO internal batting. We installed correct, Poly Spun batting internally to reduce cabinet 'ring' and tighten up the low-end considerably. All drivers were reinstalled into cabinet with ‘added’ gasketing material under their frames to further reduce any possibilities of vibration or acoustic anomalies.
Next, as always they were tested with both recorded material, PN 20-20k and swept them with our AF generator from 20-3kHz. Then came our standard, 'abusive' test recordings. Following the technical restoration / tests, they were detailed cosmetically. New acoustically transparent grill cloth was installed to the grill frames. Wood grain, vinyl wrapped finish in great shape with very little visible wear. These speakers look and sound great and are ready to go!

We auditioned this pair well. Following the above mentioned 'barrage', our demo cuts ran the gamut from Dire Straits, 'Brothers in Arms', Donald Fagens, 'I.G.Y. from the Night Fly album', Allison Kraus and Union Station (SOUNDS AMAZING ON THESE SPEAKERS), Trapt's 'Headstrong' (had great 'punch' and the speakers handled the upper power levels well), and a few others, all digitally recorded and some 'DDD'.

Fine sounding EPI A12, 12" 3-way, 'Bass Reflex', bookshelf speakers. Accurate, and 'punchy' sound reproduction. Great balance and detail oriented speakers. Great speaker for up to 'medium loud' volume levels. While these do get reasonably 'loud' and handle power WELL, they are more "detail" oriented speakers not "Power Pounding, Party" speakers (yes they get loud, but that's not their "forte"). As we alluded to earlier, the bass is huge, solid and deep at the same time. Just great 'all around' speakers for most listening situations and systems.

 Features:
  
- 3-Way, Bass Reflex design
- 12" Pulp Woofer
- 6" Pulp Midrange
- 3" x 5" CD Horn Tweeter
- Real Crossover (not just a filter cap)
- 1 7/8" Tuned Port for extended low end
- Dual Attenuators for Mid and High end tailoring
- Spring loaded, 'push clip' inputs
  
  Original EPI A12 / A1200 Specifications:
  
- Overall Freq Range: 35-20kHz
- System Impedance: 4 Ohms
- Sensitivity: 93 dB
- Crossover points: 500Hz & 4,000Hz
- Recommended amp range: 10 to 150 watts
  
Again, as stated earlier, our speaker tech has completely refurbished them, then they were tested them including sweeping them with an audio generator looking for any acoustical anomalies or extraneous noises or sounds. Also tested with our extensive CD library of "audiophile" test CD's. They work and sound great! These speakers also function best with little or no tone control and are best, not used with much equalization. 'Loudness' control would likely be 'over-kill'. Each measures 26" high x 15.25" wide x 11.5" deep and weighs 32 lbs. Includes our standard 90 day limited warranty (excluding problems due to under / over powering).

 FISHER SPEAKERS
      MODEL ST-750 ST750
#...0744 / 0745
 Circa Early 1980's
'Military / European' market speaker
 Made in Chatsworth, California, USA
 for sale
 Big sounding Fisher 3-way, 4-driver speaker system. The Fisher ST-750. This is a rare model in the states, as it was sold only in Europe and Asia and for the Military markets. Nice, big, 'Wall-O-Sound" experience. Very efficient. These have 2-position attenuators for the Highs and Mids, which will be handy as they are not lacking on either. Especially good for someone who is deficient in those frequencies. For the rest of us, they excel with the attenuators set on '-3dB'.
We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator.
 Features include:
 
 - 3-Way, 4-Driver, Bass-Reflex cabinet design
 - 12" Fisher 12101 Woofer with fresh, surrounds / suspension installed
 - Dual 5" Fisher 502 Cone midrange
 - 3" Fisher 351 radial horn tweeters
- Dual 3-Position attenuators for Treble Brilliance  & Midrange Presence control for tailoring mid and top-end
- 5" x 2.5" Tuned port for extended low end
 - A "Real" internal crossover, not just a cap on the tweeter, so the woofer gets "just lows"!
 - Circuit breaker for tweeter protection

Specs:

Frequency Response: 40-20,000Hz +/- 3dB
Efficiency: ~94dB 1w @ 1m
Nominal Impedance: 8Ω each
Cross-over frequencies: at 1kHz & 5kHz
Recommended Power amplifier rating: 20-100 watts

 Our speaker tech has completely gone through and 'Certified' these. We have completely disassembled these speakers prior to restoration. Fresh, new foam surrounds installed on the 12" woofers. We also installed fresh sealing compound on all the drivers and bezel rings prior to re-installing for maximum seal and to eliminate any sonic anomalies from driver flange to baffle board. Our technician also installed new foam tape on the woofer bezel / 'beauty ring' to eliminate any sympathetic anomalies. Only issues are cosmetic and they are that the midrange grills are missing on one of the speakers (cosmetics only and does not affect sound) and there's the obligatory snags to the knit grill cloth and the 'Fisher' logos are missing from the grills. Original grill frames and attachment pins all good with no breaks. We have completely tested all drivers. Tested for all frequencies from 20-20,000Hz with a sweep generator. Wood grain vinyl wrapped cabinets in great condition with a few normal scuffs and have been thoroughly cleaned. Great "all around" sound and get very loud! Each measures 27.25" high x 18" wide x 13.5" deep and weighs 45 lbs each. Includes our standard speaker warranty (excluding problems due to under / over powering).

 STEREO SPEAKERS
 EPI 140C
 #...3071 / 3077
 Circa 1979-1981
Made in Newburyport, MA. - USA
 for sale
 First pair of 140C's we have had in 15 years. Great sounding EPI 140C, stereo speakers. Very accurate 2-way / pseudo 3-way design reproduces very nice detail coupled with great 'balance' and surprisingly good power handling. Not a particularly efficient speaker (84dB), so will actually be happier with some medium to larger power amps / receivers (probably something above 30 wpc 'old school').
 Features include:
 
 - 2-way / 3-way, Passive Radiator design
 -6" Low Frequency Driver (woofer)
- 8" Passive Radiator w/ non-deteriorating Butyl rubber surround
 -1" Inverted, Hard-Dome "Air-Spring" Tweeter
 - Real internal crossover
- Tweeter Level Control
 - Very heavy, solidly built cabinets
 
 Specs:
 
 Frequency Response: 38-20,000Hz +/- 3dB
 Efficiency: 84dB 1w @ 1m
 Nominal Impedance: 8Ω nominal
 Cross-over frequencies: 1.8kHz
 Recommended Minimum Power amplifier rating: 25 watts minimum  (I would recommend no less than a 35 watt amp)
 
 From some original EPI literature, "Rather than making outlandish claims backed up by dubiously acquired specifications, EPI is quite reasonable in stating the frequency limits of the system. The actual sound is excellent with bass response remaining crisp and tight to the lower response limit. The treble response is clear and airy. Overall this is an excellent speaker and a very good value in it's price range".
 Our speaker tech has completely gone through and 'Certified' these. We have just installed fresh, new foam surrounds on the woofers for trouble-free service. We also added gasket material under the drivers to improve seal and reduce vibrations / sonic anomalies. We completely tested them including sweeping them with PN 20-20k and an audio generator looking for any acoustical anomalies or extraneous noises or sounds. Cabinets are REAL Walnut wood veneer and are in fabulous condition. Just had a fresh coat of 'Feed-n-Wax' and look near new. The original grills and grill cloth also in GREAT condition. These are great, 'all around' sounding speakers. Great examples of the classic 1960's thru 80's 'New England' sound. Each measures 24" x 13.5" x 9" and weighs 28 lbs unpacked.

 STEREO SPEAKERS
           YST-A755 YSTA755
 #...2277 / #...2305
 Circa ~1999
 for sale
 We aren't typically very interested in A/V speakers, but these Yamaha YST-A755's can hold their own in our 2-channel system. This speaker is large enough, that even though it is a modern, A/V cabinet, it sounds great on an "old skool", 2-channel amp!  Great speaker for detail, balance and that big "wall-o-sound" presence. Handles power VERY WELL!
We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator.
 Features include:
 
 - 2-way, Bass-Reflex design
 - 8", Polypropylene, Low Frequency Drivers (woofer)
 -1" Soft Dome, coated cloth Tweeter
- 2.25" tuned port for extended low end
- "Real" internal crossover (not just a cap on the tweeters)
- All original Yamaha made drivers
 
 Specs:
 Efficiency: ~88-89 dB 1w @ 1m
 Nominal Impedance: 8Ω each
 Recommended Minimum Power amplifier rating: 10 watts
 Max power rating: 160 watts
 
 
 While these speakers are not our typical fare, they are great sounding 2-channel speakers (yes, of course they would sound great in a theater / surround system) By nature, the "tall" stature of the Yamaha YST-A755 puts the tweeter more on plane with your ears, instead of your knees.
 
These are some what "cosmetically challenged" up close, but nothing too distracting. One of the cabinets had some wall mounting brackets bolted in to it so it has a few small holes and both speakers have a few minor scuffs to the satin black, wood grain finish. The original black knit grills are in good shape with a few very minor snags and one is missing the "Yamaha" logo (see far right photos above. The photos were taken at close range with a flash and make the blemishes look very much more noticeable then they are in reality). Grill frames perfect with no broken or repaired parts.

 Again, both woofer surrounds freshly replaced for  years of trouble-free service. Great speaker for up to fairly high volume levels. These are "detail" oriented speakers that can also get loud and fill a room. Great for about any type of music. We tested them extensively and have temporarily added them to our audition line-up because we were so impressed. If you're looking for "true" wide frequency response, balance and detail and a speaker that can handle power well too, then these may be the speaker for you. They ROCK!!! This would be a great speaker for a room with limited  space, but you need to get loud as the cabinet has a lot of cubic volume, but with a small "foot print".  Cabinets measure 33" H x 10" W x 11"D and weigh a hefty 39 lbs each. Includes our standard 90 day limited warranty (excluding problems due to under / over powering).

STEREO SPEAKERS
       CS-53 CS53
Circa 1970-76
MIJ
  Early versions of Pioneer's CS series. Solidly built of plywood (most speakers, except Klipsch use particle board), simple 2-way speaker. These speakers were one of the most surprising we listened to in a while. Given their lack of internal sophistication, we did not expect much, but were more than pleasantly surprised. They handled some of our most difficult test cuts fabulously. Great low end punch with out being mushy, just enough hi's and mids (without any EQ) and very pleasing overall. Handled our Hafler power amp fine, would really shine on a low powered tube amp or where you need an efficient speaker for that vintage lower wattage solid state, receiver such as a Marantz 2210-2230, Sansui 221, 331, 441, 250, Kenwood KR-2400-3600 or similar.
 Our speaker tech has completely gone through and 'Certified' these. We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator.
 Features:
  
- 2-Way, Bass Reflex design
- 12" Low Frequency Driver (woofer) and Non-deteriorating cloth surround
- 3.7" Non-deteriorating paper surrounded, tweeter
- 1/4" phono and "Binding Post" input jacks
- "Real" internal crossover for accurate distribution of frequencies
- 1" x 8" Bass Port
 - Plywood cabinets with real Walnut wood veneer finish
 
 Specifications are:
 
 Impedance: 8 Ω 
 Frequency response: 45Hz-20kHz
 Efficiency: 94dB 1w @ 1m
 X-over point: 3,000Hz
 Power handling: 40 watts 
  
  Unfortunately these speakers are fairly cosmetically challenged with numerous "battle scars" to the real walnut wood veneer cabinets. Nothing independently too distracting, just numerous scuffs and dings and some de-laming on one top (see photos above).
 These are very "live" sounding speakers with great punch and bottom end definition. Nice "Wall-o-sound" sonics and very efficient. Original cloth grills in great shape. All the drivers are in perfect working and cosmetic condition! Cabinets, while dinged have just had a fresh, hand-rubbed coat of bees wax and lemon oil. Each measures 22.75" tall x 16.5" wide x 11.75" deep and weigh 28 lbs unpacked. Includes our standard 90 day limited warranty (excluding problems due to under / over powering)
