I'm trying to decide between the M2i's and the m22ti's. My room is 300 square feet. I'm using a 70w per channel receiver (Yamaha rx-v595a). Will the m2i's be able to do the job, is the m22ti overkill for my room? It's also interesting that, based on the NRC measurements in the recent soundstage review, the m2i's have a higher efficiency rating than the m3ti's (86.5 vs 86), so I'm thinking the m2i's should do fine?
