I ran an M2 center for a while -- worked OK with only a tiny bit of fringing if I had it "tweeter down" on the TV. Ended up buying a VP100 rather than another M2; partly for the shielding, and partly to see whether the 2nd midrange made a difference.

Having said that, you could do a LOT worse than starting off with 3 M2s and a big honkin' sub. You need a big sub to fill that room... more than you need big mains and center.
