Dialing it back is a reasonable suggestion. The subs in sum are calibrated to 75dB using the tone from the receiver (BTW that took more work than time and phase aligning). It sounds and feels wonderful for movies and music except for the fact my ear drums feel like compressed air is being pumped into them. I guess that's what good subbage is supposed to feel and sound like. laugh

Point taken. I shall attenuate and gauge the resulting physiological and emotional responses.
