2. Aim the speakers directly at the two main speakers, matching height to height. If the room is sparsely decorated, it may be necessary to slightly tilt the speakers down to increase sound quality. If the room is densely decorated, it may be necessary to face the speakers toward the rear wall or at the ceiling.

3. Mount the speakers up on the ceiling. Set them a few feet wide of the listeners and make sure they are facing one another, not the floor.

Obviously there are many more possible positions, so it may be necessary to simply experiment to find the right balance for your situation.

the room where you are most likely to be when

listening to your system. The rear surround and

center speakers should be adjusted to equal the

level of output from the left and right main

speakers.
