Use of two rather than one back surround is suggested both to take advantage of a possible left back/right back difference and to avoid a psychoacoustic "reversal" effect in which a center back sound is instead heard as being center front.



I think this is the biggest reason 7.1 came to be over 6.1. Your ears are designed with better sensitivity toward the front. When we have more content with the rear surround channels it will become more commonplace and certainly of greater value.
