With 1/2 way Gain mark on the sub is set, my Audyssey MultiEQ - XT is performed. After calibration I have to turn the Gain down to 9 o'clock, for best performance, for my ears/room. My HT room is 8 X 12. I forgot what the original calibration level is, and probably -12. No big deal, in my case. DD movies do not miss a beat. Internet Music is good, too. Nothing to worry about with -12.
