Welcome to the forums odg.

From my impressions that I have read on the forum in regards to M3 vs M22 is that the M22 is more detailed and the M3's have more perceived bass when ran full range. Some users also give the M22's a increase in the bass tone controls to mimick that of the bass hump in the M3's. Both are excellent speakers, the M3's are just slightly more laid back when compared to the M22's (even though I would not call the M3's a laid back speaker).

Enjoy your Axioms!
