i have a 92" screen and im at the ending stages of my basement project. i think i ran the speaker wire to high and am not sure the speakers would look good or sound good. the way it is now the speakers would be about 4 1/2 feet off the ground. if i center the speakers the speakers will be just under 4 ft from the ground. the screen is kind of low to the ground (21" from the ground) so im not sure that the speakers should be higher, lower or just centered on each side of the screen. its really a minor problem but with the drywall not tapped and mudded yet i still have time to move them around. here are some pics of what i have going so far..

The screen should be 1/3 of the screen below your eyes when seating.
For the speakers the height is not very important as long as they are directed to your ears, if they are to high you just nee to put a little angle towards the floor, directing the sound to your ear, but ideally it should be to your ear level.
