Dduval,

I have a Denon AVR 3311CI

I did the auto calibration but don’t remember the initial physical volume setting on the sub, it was whatever Axiom recommended. I had to keep increasing it physically on the sub to get expectable bass. My current bass channel level on the Denon is -1.5 DB and the physical control knob on the sub is at 2 o’clock. By the way the installer didn’t touch the bass or AV programming, maybe a mistake on my part.
