Mike, I was a customer of Audio Concepts from the late 80's forward.
I purchased a pair of the huge mono subwoofers and rosewood monitor cabinets made by Clarke Specialties. If I remember right, the subs were designed by Jack Caldwell, and with the Dynaudio 30W100 woofers, it made for possibly the finest subwoofer sold anywhere at the time.
Interesting side note, Bob Clarke from Clarke Specialties, agreed to use solid Brazilian Rosewood for the side panels for an extra $300. I remember he said that it was the only pair he'd ever done that way. The monitors and subs were stunning in rosewood, and the sound was better than anything i'd ever heard in the high end shops.
You guys had all the bases covered in those days, and it was a pleasure to be able to work with you all. I remember the guy I talked to most often was Terry, who had all the answers I ever sought out.
