At the risk of straying on topic (hey, it is page 5), I'll add my observations on the M2.
I use them as dual centers for my M80s, but have listed to them in stereo a couple of times. They are impressively clear and sound every bit as good as other Axioms in the line. What they lack is bass, but a sub will take care of that.
I will agree with Johnk, 3 M2s across the front will work well in that room. Since you are using these mainly for movies and gaming, where surround sound is critical, don't cheap out here. Go with the QS4.
