Is there a guide out there (from the DD or DTS folks?) that shows the suggested distances b/t speakers, placement, etc? What I've done in the past is make the front L/R equidistant from the center and tried to keep the fronts of all 3 front speakers on the same plane. I.E. "straight across." Surrounds were placed about 3-4 feet above my ear level in the seated position, about 2 feet behind me. I always wondered if I got it right? *edit* DARN. Wrong forum! I thought I put this under "Tweaking." :b Mods, please move.
