Thanks Jc.

I don't want to cut into the walls if I can help it. I would be only using the speakers for watching movies and although if I listened to the on-wall and compared it to the bookshelf speaker I might be able to hear the difference, I think for my movie watching the on-wall should work great.

I have to admit what's swaying me is the great price. The Definitive technology XTR-50 I am also looking at are $700 each, so for three I'm up to $2100 and with the M22 and VP150 combo it comes to $908, a considerable savings!
