Just wondering what the best place is to place the surround speakers in a 5.1 setup. Is it best to place them facing each other on the sides of the listener (like dolby recomends) or to put them facing the front speakers behind the listener? My room is a rectangle at 23' x 10' and I have about 7 feet of space behind my chair so I can place them comfortably in either position. What would be the optimum height for the surround speakers? Do I want them higher than the front speakers (which I have read should have the tweater at ear level)?
