Just wanted to follow up on Jason's recommendation of getting an M22 as a center...

I measured and from the bottom of my screen to the floor is 35" so in fact I do have room for an M22. Due to floor space issues I plan on going in-wall/on-wall, that configuration of the M22 is 20" high. Whether I go M2 or M22 for the center either way the tweeter will be at ear-height, just wondering what I'd be loosing by going with the M2 over the M22 for the center and would it be noticeable? To recap, my HT room is about 12X17 and I'll be sitting about 16' away from the screen.

Appreciate any input.

Bob
