Tough to answer since it would depend on how loud you would be playing them. If you haven't studied the excellent SoundStage review and NRC measurements of the M2 it'd be worthwhile to do so. SoundStage has similar measurements on the M22 and M3, and the M22 does have the capability to play louder with low distortion than does the M2. Whether this would be significant for your use would again depend on the sound levels you used and can't be stated with certainty.
