DCM QED


Hi, came across a pair of QEDs, which from the outer appearance, in very good condition. Because the rubber cover cannot be removed cannot tell the under the hood condition but Im assuming good also for its age but prepared for  potential issues. So a few questions, any general thoughts on this 40 year old speaker? Do you recall if the surrounds are foam or rubber, and based on the description what would you consider a very fair and not insulting to the seller price offer? This would be mated to a Yamaha cr 820. Thanks much, Dave

The surrounds are rubber and should still be good! Early versions used Philips hexagonal frame 6 inch woofers glued into the baffles. Later custom round frame woofers replaced the Philips. Tweeters remained Philips mylar domes with wave guides (response 15 kc). Ported cabinets - prism-shaped for the TW's and rectangular for the QED's.
I am presently listening to a pair of TW's (52779, 52780). My third pair! RGR 4 preamp and GAS Son of Ampzilla. Speaker wire is Q Audio Time Stream (1980's). A real nice retro system I put together from my collection of vintage gear! 
A fair price for the QED's would be about $250. Your Yamaha CR820 will work just fine, though I encourage you to eventually get a pre/power amp similar to my own setup. DCM speakers do really benefit soundwise from better quality electronics! Enjoy!
@roberjerman,  I remember Ampzilla. I didn't know he had a son
@OP, DCM is one of the speakers I still remember from my early forays into hifi stereos. They and Vandersteen are etched into my mind.
