How far away should surround speakers be?
For best results when mounting surround speakers on a rear wall, position them so that they flank the main listening area and point toward the front of the room. They should be raised to a height of approximately six feet and should ideally have a minimum space of six feet between them, as well.
Should surround speakers be on the side or behind?
In a 7.1 system the side surrounds go to the left and right of your seating position and face you. The rear speakers go behind your seats, angled in. Your surround channels should at least be at ear level, and can sound even better when elevated by a foot or two.
What is the best way to set up a surround sound system?
You should place the front left and right speakers at a 22-30-degree angle, and the subwoofer should go on the floor on either side of your screen. Ideally, you want the two front stereo channels to be at ear-level and about two to three feet away from the wall.
