My question about the VP180 was only that you propose to mount it on the ceiling?

If you are going to have good subs serving also as stands for the mains, the M60 would appear to have no advantage, and the height of the M22s would fit better.

If you have enough distance behind your listening position to the back wall(say at least 4')for a rear sound field to form, then the use of back surround speakers can be a benefit.
