Well the price difference between the EP500 and the SVS PB12-Plus is a big factor. I won't pay that much for a sub unless it also does my laundry.

I am not sure about the gloss vs standard finish... will have to check with the wife.

My major dilemma is the M22s vs the M60s and the M22s vs the CP150.

Nice pictures by the way (and how do you like your HSU sub? If they made those in wood finish they would be in the running).
