How much different does an "on wall" Axiom center sound than their stand-mounted units? I've owned the VP180 (version 3?) and a VP-100 (version 4) before and the latter better matched my main speakers. But the current equipment configuration precludes the use of any center at ear level. Therefore, I'm thinking of mounting the center on the wall above the TV. This location has the advantages of being perfectly centered for all viewers, and of providing minimum interference when listening to straight stereo.

So my options are VP-100 on wall or VP-150 on wall. I don't play movies loudly, so either should provide suitable service. I also have a good pair of subs that can pick up the slack in the bass. So recommendations?

My opinion is worth exactly what you're paying for it!
