 Our speaker tech has completely gone through and 'Certified' these. One of the first things to address was the lack of internal batting material, which generally causes cabinet ring and excessive resonance. Our tech added poly-spun batting to an appropriate level, which in once everything else was done, really tightens up the low end and GREATLY improves definition. He then replaced the woofer surround with correct and fresh foam suspensions. All drivers were re-installed with the addition of gasketing material to further seal and eliminate any ‘flange to baffle’ rattles and buzzes. Attenuators 'PAINSTAKINGLY' removed and cleaned for ‘static free’ operation. Gasketing added to the attenuator plates prior to re-installation as well. All drivers were then tested with AF generator sweep, PN 20-20k and our standard, 'abusive' test recordings.

Following the above technical work, we auditioned this pair extensively, not because we had to, but because it was fun. Following, of course our normal barrage of 'pink noise' and an AF sweep from 3k down to 20Hz, our demo / testing CD's / cuts ran the gamut from....
