Posted in the sub forum. Thanks!I believe you might have better luck asking on the subwoofer forum. As far as I know, you only adjust the sub settings via the back panel (on the sub itself) not in the AVR. The only setting you adjust on the AVR for the sub as far as I know is the channel level once it has been calibrated, but that is if you want to rub the subwoofer HOT. Like say, the MCACC calibrates your subwoofer trim level to -10, you can adjust it to -6 to run it 4db hot.
Just remember that the subwoofer might have a different response in your room vs someone else's room, so it will depend on the in-room gain.
And if you have multiple subs you might be better off adjusting/integrating both with a MiniDSP , but again you would get a much better answer/informative response on the Subwoofer forum section. Good luck!
