I am considering buying new Axiom speakers. I run a 6.1 system (110w/channel). My room is 16x16 with a cathedral ceiling that opens to a loft. I was considering the M22 for fronts, the VP 150 center and QS4's or QS8's for the three surrounds. I was also considering the EP175 sub. Would these speakers be sufficient in this room. I sit about 10 feet from the screen. I currently have a Polk RM6700. Any advise would be appreciated.
