I'm considering changing my system to a flat panel TV and on wall speakers. I have QS8 surrounds currently and would like to match them with M22's in the front. I think they would do fine for movies but music might be lacking. So what if I stacked two M22 on walls on each side(4 total) along with two M22's for center's (one above and one below)? This would keep everything uniform across the front and the extra drivers should help give more midbass.

The room is large at 19 x 19 with an 11 ft ceiling. Axiom's HT calculator recommends floor models, which is what I have now (although not Axiom).

Thanks Mike
