I own a pair of M22s, gave away my M3Tis. As stand alone speakers, IMNSHO, there is no comparison ... the M3s are much more enjoyable without a sub. The M22s are excellent speakers though to my ears they sound a bit flat, sterile. The M3s on the other hand are awesome speakers ... Axiom's best in my opinion. The M22s improve greatly with a sub, however, if you intend to wait for a sub, swap those 22s for a pair of 3s.
Good luck to you and welcome.
