I have a 6.1 system by pioneer on my 65 HDTV and am curious about speaker height. I have the wires run in the attic and the speakers are on brackets that are directly off the ceiling. I have 8 foot ceilings so i'm guessing the speakers are 7 1/2 feet off the ground. From reading the Dolby page, It seems as if I have them too high; however, I have them angled downwards towards the listening area. Is this a good enough format to remedy the situation. In addition. my center speaker is a good 2 or 3 feet lower than the fronts, should I leave it and lower the firing level of the fronts as well or make a shelf for the center? I figured a shelf would make the speaker too high. at least the other speakers are firing downward.
