Still searching for that small speaker!
Hello gentlemen,
After dropping in and reading your forum off & on for years now I finally had to join! I wondered if someone familiar with the CM6 and CM7 could offer some advice on what they sound like? To put it into perspective I have owned multiple pairs of the little 300's from the car speakers, L300s I think, 300i, 315i, 320i, (and one 200 box), L810's, L880's, M15's but I've never owned a 400 or 500 series. My latest purchase was the CM60. Well I was looking for a small bookshelf speaker about the size of the L400's or CM60 to use as surrounds. Pretty disappointing. I suppose not so much if you consider them a $150 speaker instead of an a/d/s but by comparison my 13-year old son has a cheap pair of HK bookshelf's which seem to do just about everything better.
So, can anyone comment on the sound of the CM6/7 with respect to the older 2-1/2" mid+1" tweeter combo or the newer M9/12/15 mid/high sound? Or perhaps recommend something you feel sounds as good or better but is easier to obtain? I would like to stay away from any of the older paper drivers & foam surrounds for obvious reasons.
As a side note I've read a fair bit about the comparison of the Unison speakers to the older L810,1090,1290,1590, etc, here and on other forums. And if I may add my humble opinion, the M12, M15, & M20's do everything better than their predecessors did. In many a/b comparisons between the L1590 & M15, the M15 (with the newer crossover) produced deeper base albeit perhaps not quite as much. And the mids effortlessly produced nuances you wouldn't even notice on the L1590 unless you heard them on the M15 first. I owned L810's from 1980 (I think!) until 1991 when I bought the M15's. I had a good friend with the L1590's which was my motivation to have a pair of the 15 series. I ran the L810s with a pair of HK Citation amps of the same vintage. If memory serves they produced somewhere around 330w each at the nominal 6ohms of the L810. I sold all of that to my brother and purchased an Atelier system along with the M15's. To be honest the electronics were a step backward except for that remote control!!! But we spent many an evening listening to all three pairs back to back and the older mid/tweeter can't even come close to producing the nuances the M15 does.
Also had the opportunity to spend quite a bit of time with the M20 (became good friends with an a/d/s dealer who owned a pair!) Seemed to me that the mid/highs were exactly the same as the M15 but seemed less forward due to the much increased bass output of the M20. Driven hard the M20 produced more bass than anything I had ever heard then with perhaps the exception of the B&W 801. But the M20 was still tight unlike the wild 801. And those were driven with a pair of Levinson mono blocks. I don't know which model as I new I could never afford them so I didn't bother to look.
Anyway, after living with the M15's for 17 years I thought I'd throw my humble opinion in there. If you find a Unison speaker they often sell cheap because few know what they are. I promise you won't be disappointed if you pick up a pair. But don't expect miracles without good electronics. I do believe my M15's sounded noticeably better on my brothers HK electronics with a bunch of power where his L810's don't seem to sound any different on my Atelier stuff.
