Thanks for the responses. In terms of tweaking the placement with freestanding - sure you can. But reality is, sub aside, the speakers are going to have to be in fairly specific spots - but of course there is room for a bit of movement.

What would you crossover the free standing m22's at? also, I assume the same thing stands true with the v150 on wall? Probably not as many lows going through the center channel - so maybe not as big an issue?
