Ry, you didn't hear that M3 better than M22 bass stuff from me. As I've pointed out here several times, the NRC tests showed that the M22 enclosure was actually tuned about 5Hz lower than the M3. The M22 has slightly lower "real" extension(disregarding the apparent effect that the M3 "hump" gives). Yes, my findings when I used the M22 without a sub were similar to yours: sufficient bass for most music(pipe organ excepted).

Enjoy the music, not the equipment.
