My physical gain knob is @ 3.25 out of 10
Avr is Denon avr-x1400h
0db speaker level (setting , speakers ,manual setup, level)
-10db subwoofer trim (settings , audio, subwoofer level)
I don't like running my subwoofers hot .
At -12db (sub trim) it almost disappears at -10db the bass has a tiny bit of meat on it .
This is all temporary, I'm waiting for an spl mic
And will most likely use REW down the road with a USB mic (future project)
