My friend Rodney did the majority of the work. He is a contractor and very skilled.
Panning to the right, you can see the surround speaker bracket on the wall, and beyond it, the computer alcove, then the rear bay (which matches the front bay where the TV lives).
So, I have been enjoying the TV and surround setup for a week or so now. The new Onkyo receiver has great sound. Rodney was given a movie night last Friday and he declared the picture and sound was just like at a theatre, which is the whole idea.
