My first setup was M60's with a VP 150. It was good, but the center could sound a bit boxy to me off axis. It was the best I could get at the time. The soundstage was close but not seamless. Waiting on my VP160 (delayed by the ceiling speakers) to compare, but with the same driver array as the M60's it has to be better.

Someone mentioned the crossover, I was actually wondering if letting the VP160 do some of the 60-80hz stuff might sound tighter than letting the sub do it. It'd be interesting to A/B it.

Let us know how the 180 stacks up.
