GT, welcome. The M22s plus a good sub(which you'll be getting)form an ideal combination in my view and I've certainly found no significant limitations in my use of the M22s plus EP500. The size of the enclosure affects tuning for low bass extension and loudness, but isn't a factor above that. The thought sometimes expressed that a tower speaker "fills" a big room with louder sound has no factual support above that bass area; the drivers, not the enclosure size, determine that. The M22s have no deficiencies in that respect and are at least the equal of the M60s, if not slightly superior in the all-important mid-range because of the dual drivers. Your sub will supply excellent bass extension and loudness.

I'll also suggest using QS surrounds and not to be concerned about a nominal 4 ohm impedance rating on a speaker such as the M80, which is above 4 ohms for the majority of its frequency range
