there are two settings on receiver, which one should I make 0db? the LFE level or the Sub Volume Level (speaker calibration settings). If I understand you correctly and assuming you are referring to the sub volume level, you want me to set the sub volume level to 0db and the sub gain to min and then slowly turn the gain knob to achieve the SPL 75db measurement, is this right? Well I actually tried this already, and if I can recall, the gain control only reaches one to two bars from the min(0) level. Is this normal?
