And I even looked first too. Well, my wife does say I can't find my nose.

But wow. I would never have even considered M2s for that size room.
That's roughly 2500 sq; I have M80s in a 2000 primary (LR), 3500 total area (+DR+kitchen); albeit just stereo, no sub. Maybe I've been over-compensating.

So when would you use M5s, what's the cut-over? (Room size, use, something else?)
