Thank you very much for your advice. I already have a calibration DVD, and I will get the sound meter as soon as possible. In the meantime, I set all the speakers to small and put the crossover range to 150. I just finished watching The Patriot and at times, it's completely obvious when the subwoofer takes over, because the sound just suddenly stops from that channel, is that normal? Also, I have the sub at just past half set at video and the phase at 0, but I can barely tell that there's a subwoofer at all. Should I crank the sub level all the way, or should I even have to do that?
