Movie Theater 7.1 surround is used in larger sized theaters. Two extra speaker channels are added to the front mix: one between the left front and center front, and one between the right front and center front. However this would be impractical in your house because most home theater rooms are much smaller.
So for home theater 7.1 the two extra speaker channels are placed at the side of the listener, halfway between the front and rear speakers. For easy identification purposes we’ve labeled the two channels for movie 7.1 as Left Center and Right Center and for home theater 7.1 as Left Side and Right Side. Each channel contains audio that’s specifically from that area of the sound field for a perfect match.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
