I've found it better, at least for my situation, to be a few feet further back then my 80's are apart, or even my 60's when I had them. They are about 11ft apart, and I sit back about 13ft for the main seat, however, the sound is even great for the rear seats as well.

I would not spend to much time dwelling on be exact.
