I think crossing the M22s over at 150hz is ridiculous. No need to exaggerate your preferred listening sound mo. I have mine crossed at 80hz and it sounds amazing.
pgans, another thing you may want to consider is dual centre channels, instead of a VP100, you can have a pair of M2s wired in parallel (one above the screen one below) for an amazing sound. (better than the VP series IMHO) and two M2s cost about the same as a VP100 (but you have to buy mounts too).
