Mojo is spot on. So many people still have the misconception that the center channel just does dialog. That is far from the truth any more. My center channel, the VP180, is really big, even compared to my left/right mains (M60s) and when I go through calibration (automatic, manual, or just listening to scenes in movies), there is a large amount of sound energy coming from the center channel. It is actually used almost non-stop during all movies, even when nobody is talking. I definitely would not skimp on the center.
Either the VP160 HP version or the VP180 should be on your list of considerations.
