The area that I am in the process of developing into my HT is a basement room that is divided with the HT on one side and a wetbar game-table area on the other. Each area is about 15x20 sharing an open border. I don't know if the open area to the left of the HT area matters, but with all of this talk of "moving air" with the speakers, it seems that it would have some impact.
