I have owned the M3ti's for a couple of years and must concur with 2x6spds...they are great! I have never had a time where first time listeners don't ask about them; they are always impressed. Some who have spent multiples of the price for their systems come away shaking their heads. They can't believe the sound. I have powered them with a 50wpc Denon receiver and my now current Denon DRA685 (100wpc). Both receivers sounded great. My system is located in a very large basement (1600 sq. ft). Even in this large area they still play to fairly loud levels. I have found them to sound good with all types of material too (rock, jazz & classical). Live recordings especially sound good. The M3ti's can also faithfully reproduce harder rock music with force (i.e., Metallica's Black album)...and I'm NOT running a subwoofer. To say I am pleased with them is an understatement. They are, IMHO, one of the best deals in audio.
