I have Cox HDTV/DVR service and I have noticed that both my surround speakers LS&RS seem def unless I crank up the fader to the max 12db's. When I pop in a DVD the RS&LS are so loud that I have to turn them way down to 3&4 db's, my fronts are @ 0db's. I have a Denon AVR 5700 140watts X5, with my front speakers @ 4ohms and rear's @ 8ohms and am using fiber for sound, have tried coax no change. I give a huge breathing room for my Denon as the temp. sessitive fan only turns on when I really crank it up but I don't do that very often. My signals are perfect as my internet speeds are 12-16 megs, signals are: Ds SNR32.9, RX 1.9, TX 42.1. SO WHATS UP???
