I do have a 120 in" screen, which i currently watch from about around the same distance that I have it laid out for the new floor plan.

The surround sound is definitely the biggest point of interest that I am curious about.... I could take me rear surrounds all the way to the back of the room and give them a bit of volume, and then the could actually be facing the center of the room a bit closer together, but they would be fairly far back. I also do have an extra set of speakers that I could add to my surround sound amp and give a wide sound stage for the rear surrounds... not sure exactly how that would work out.

I understand that having one wall along one side, and no wall along another can cause a bit of of unbalance. however in my current setup the left side only has a half wall bar, and I can really sense any difference. How much of a difference does it really make to have a back wall or higher ceilings? Will the main problem be echoing and sound direction confusion?
