Thanks for the posts!

I am doing a 5.1 at this time. I'll probably expand to 7.1 when there is more source material available to take advantage of it.

I'm just finishing the install of my Axiom VP100 center channel. I opted for in-wall to try and keep curious little one's from poking at them.

More than anything I've been fretting over the rear placement. I suppose I also have the Audyssey in the Denon receiver to help compensate if it's not perfect placement.
