Just recently upgraded from on older ProLogic receiver to a new one with "the works". Anyway I've noticed that while watching my digital (downmixed to prologic - no digital output) cable in ProLogic or ProLogic II movie mode I don't get much output from the subwoofer. I ran the auto calibration on the receiver and it seems to have done a respectible job. Movies sound great in DTS or Dolby Digital. The sub crossover is set to 80Hz and front speakers are set to small. Now with my older receiver, I'm not sure at what level it ran signal to the sub but it did have more emphasis. Of course I had no control over speaker settings, etc... Is it just the lack of LFE signal in normal broadcasts that I have noticed my difference?? Just looking for some suggestions.
