Just to clarify. All the speakers need to be on wall speakers except for the sub-woofer. I plan on trading in my bookshelf M22 for on wall M 22. You guys have convinced me to go to a VP 160 or 180 for the center. Which on wall speaker from your experience will sound better with this setup the M2 or M3? Again all speakers have to be on wall. I addition how far from the sidewalls should the M22s be for best sound?
As far as the Sub-woofer I am going back and forth between the EP 350 and the EP 500. It seems that for my size room the EP 500 is a better choice. Given the cost though I wonder if I could get away with the EP 350. My other option is to stick with the Klipsch sub-woofer I have and see how it sounds.
