. . . Some theaters are already running 7 discrete channels, but they are left, left-center, center, right-center, right, surround-left, and surround-right. That makes more sense because the screen is so large.
Hi ClubNeon,
I think that what you are refering here to is Sony's format for commercial movie theatre called SDDS -
http://sdds.com/.Dolby's 7.1: According to an article in Widescreen Review . . . An interesting point is that even the rear speakers should be located on the side walls not the rear wall . . .
" The optimum 7.1-channel surround format for home theatres is to position the "two added" channel loudspeakers to the sides, not to the back of the listening area."
