I think the difference between the M3s on regular vs. factory outlet stock is just a question of web site updating. The FO products are normally identical to the ones being shipped except for minor cosmetic defects. Never hurts to give Axiom a call to be sure though.

Your room size is in the range where anything from M2s to M60s would be OK although M2s would be marginal if you want to play loudly. M22s are the biggest you could "need" in that room and will be able to survive at least your first move into a slightly larger room.

M3s are still the best "value" and some people prefer their sound for many kinds of music, but for a pure movie system I would probably try for M22s if you can. There are still debates about "accurate vs. smooth" sound for music systems, but everyone seems to agree that the most accurate speakers sound best for HT.
