What do you all think of the VP 150 center channel? I've read both positive and negative views on it. If I go bookshelf instead of floorstanding speakers I gather it is a better match than it's big brothers.
I would stick with the VP-160 or 180 if you are going with a horizontal center. Have you considered vertical center? If so you're best option is simply get 3 M60's or 3 M80's for your LCR if you have the room.
Otherwise I wholly agree with the praise for the QS8's as surrounds. It was the quest for a better surround speaker that 1st led me to Axiom several years ago now. Good luck!
