Jason,

Thanks for the response. Yea when I had the wall unit built, I thought I was thinking ahead, but turns out I didn't consider some stuff, like the space for the floor standing speakers.

I have a 10 year old set of Mission bookshelve speakers now for the fronts and rears, and a B&W center with no subwoofer, so no matter what I decide, it's gonna be a big improvement.
