Dude, the VP150 is more center channel than you will ever need.. If you have doubts about coverage on the side, go with an M22..
I've had my Axioms for years now, and not one problem with the sound or lack of coverage.. If I changed anything, it would be to swap out the VP150 for the M22.. Why ? I would like to hear what it would sound like used as a center.. My guess, proabably not too bad..
Oh, I might add, my M80's and the VP150 are all hanging from the ceiling ! Yep.. And they blow the doors off anything else I have heard to date..
With the speakers clear of the floor, ceiling, and walls, not to mention hanging at an angle to all those surfaces, I get about as close to zero negative reflections as a guy has a right to..
But I dirgress.. Go with the VP 150.. Nuff said..


LFE ! The rest is just details..
