I'm thinking of getting the M2is to replace Infinity RS2s in a stereo-only system using an NAD C 370, a SONY DVD/CD/SACD player, and a Sunfire True Subwoofer Jr. The room is 13 x 18 x 8. Joe at Axiom has steered me toward the M22s because of concerns about getting adequate volume out of the M2is to fill the room. Although volume may be part of the issue, what I'm really looking for is better (more up front?) mid and high frequency response than I am currently getting from the RS2s. With my current system, the mid-bass and bass seem to be fine. For the record, RS2s have an 0.5-inch tweeter and a 6.5-inch woofer. What do current owners of M2is think? Will the M2is do it for me? Thanks for any feedback.
