The Evolution Acoustics MMMicroOne’s are recommended for anyone who highly values music reproduction in situations where larger speakers will not work. I played them in both small rooms (10X12X9) and the main listening room (25 x 30 with high ceilings) and the MMMicroOne’s were very much at home either place. The sensitivity is rated at 87dB so have a good 60 to 100 W per channel. You don’t want to clip ceramic drivers. Maximum power is stated at 250 W per channel. Even better. We consider the Evolution MMMicroOne as a giant killing, hi-end grand larceny. But hey, what's a little felony between friends?
