Im trying to find out specs or info on CM Laboratories, servo-feedback loudspeaker system model fifteen speakers. PLEASE HELP!

I have a full review of the C/M Labs CM-15 from the Winter 1975 issue of Consumer Guide Stereo and Tape Quarterly. MSRP was $1000/pair, it uses 2 dome tweeters, a 6" mid and 15" woofer, and weighs 85 lbs each.

A 15' cable was provided for the feedback to the amp.

The review was mostly favorable, except an upper treble peak that was observed by some on the review panel.

I can scan the review and send it to you if you like.

If you scan the review, how about also posting it either here or at HiFi Engine? I bet others would be interested.
The OP might also try the Bozak forum, since Wayne Chu, who was the C of CM posts there occassionally -- Bozak and CM had a cooperative arrangement for a while and then Bozak seems to have absorbed them.

That would be awesome Kirk! thanks for the info.

another question on those if anyone knows is, how do you hook them up? lol. there are 6 pins in the back that looks like a connector of some sort went to them. never seen anything like that before.

As I understand it, the request for docs has to be posted in the Digital Docs forum, and then I can send it to be posted. Correct me if that's not the case.

HiFi Engine has not been taking new docs for a while; I've tried a few times, and keep getting this message:

Upload Scans

The HiFi Engine and Vinyl Engine sites are currently undergoing a complete rewrite of the software. During this period I am unable to accept any new scans for processing. Once complete I will finish processing the scans already uploaded before reopening the upload form.

Thanks for your understanding and I hope you continue to find the site useful

Those are likely Jones cinch connectors.

Bozak was affiliated with C/M labs while Wayne was with C/M Labs, however the speakers were a development AFTER Wayne had left C/M Labs so I don't think he will have much information for you. Ed

Didn't know that. Given that I had no idea CM ever made speakers, I had no idea of the time frame. Do you know who designed them? Maybe Bob Betts or Peter Lederman (the guy now at soundsmith)?
