Koss CM-1010
Little is documented about the Koss CM-1010. What the record shows is mostly Koss's own introduction advertising. It was a full-page ad with a © 1977 Koss Corp. line, and it ran in early 1978 issues of the audio press. The ad presents the CM-1010 as a loudspeaker and "the ultimate in 2 bandpass speakers." It describes an 8-inch woofer that also handled midrange up to 3500 Hz, plus a passive radiator whose "unique alignment mass" was said to produce a maximally flat response from an f3 of 35 Hz.
The ad ran in High Fidelity (January 1978, p.30) and HI-Fi-Stereo-Buyers (January 1978, p.15), among other magazines. No independent period review has surfaced. No pricing, production years or additional specifications are documented either. The known facts, all from the ad:
- Loudspeaker, 2-bandpass design
- 8-inch woofer
