The way I'm resetting up my HT area, my rear speakers (I have the JBL NSP1 package) will be around 3.5 feet above the ear, and pointed straight at each other across the room. They have to be that high becase of the large picture window that takes up half the wall Will that be too high? Right now I have them behind the sweet spot pointed forward, and I don't hear them as much as I did when they were on the sides, so I'm gonna be switching them back soon as I buy new wall mounts for em.. So will they be too high? I remember reading somewhere that they should be 2-3 feet above, or was it 3-4 feet above?
