Thanks for the replies. I have another question while I wait to re-do the arrangement of my living room.

In picture #1, above the TV you can see at 8' high, there is a little ledge/overhang. Would it be worth the effort to install surround-back speakers directly underneath that overhang, pointing down?

I was thinking of putting my couch where the TV/Sub/media storage is, and moving the TV/speakers to where the couch was. This seems like my only option for Surround-Back speakers for a 7.1 layout.

Any other thoughts? It's really impossible to consider putting the TV above the fireplace, as I'd have serious issues trying to get 7.1 with the couch diagonally across the living room.
