If I go with the m22 as a center. Where would that go? I've read it should be placed vertically not horizontally so it wouldn't be able to go below the tv and would have to go on top. That would mean the bottom of the speaker would be about 4 1/2-5 feet in the air. Isn't that too high up?

Thanks for the suggestions so far. Seems most have been stating the m22's as the fronts would work well. As for filling the room with sound I want it filled in very nicely for the viewing area and am not too concerned how it sounds 25 feet away in the back corner.

About the factory outlet option. I've read a little on that about they are small blemishes and not real noticeable. They don't ship speaker that say have a big chunk out of the corner, or a deep scratch down the side etc do they? My luck I'd get the worst speaker ever shipped from the factory outlet.
