I used my CM-30's for the first time today at a gig. The room was 30x50 with about 50 people in attendance. I asked them for a show of hands if they thought the sound was better than usual. They all raised their hands and applauded.
The volume was at 2:00 o'clock and a little on the loud side in the back of the room even. The big difference was how chrystal clear the instruments and vocals were. I was afraid of the bass being lacking. I shouldn't have. I had them literally rocking on the dance floor.
Having said that, my sub on my other system pumped more air, but too much. In a way, it is not a fair comparison, as my Z2200 cost less than half of two CM-30's.
It may not be right for everyone, but I love them , and so do my regulars.
