Sonos AMP (Gen 2) subwoofer WITHOUT high pass on main speakers

Hello! I tried to fit the whole question into the title, but will clarify abit.

I have a Sonos AMP Gen 2, which I have connected a 3rd party subwoofer to using the RCA LFE out on the amp. This works perfectly, but it also activates an adjustable high-pass filter for the main speakers. I wish to turn this filter off completely and have the full range signal go to my main speakers, even though I still use the sub. I cannot find this setting anywhere. Thankful for assistance!

Or the sub? Why do you want to pass on all the signal to the main speakers anyway?

Because they are full range speakers….

FYI, from the manual of a Sub that WILL work with the Sonos Amp, wired to its speaker terminals. The Sub has a variable low pass filter and a fixed high pass one applied to the speaker out terminals on the Sub.

High Pass Filter. Removes frequency content below 80 Hz from the full-range signal sent from the Sub8 outputs. This is useful if your main studio monitors do not have their own high pass filter.
Power User Tip: Leaving frequency content below 80 Hz in full-range monitors can cancel out or reinforce the highest frequencies that are reproduced by the Eris Sub8. This can make the bass response of the overall system muddy and ill-defined. By rolling off your full-range speakers, you will create a more linear frequency response between the subwoofer and full-range content.
Low Pass Filter. This control determines the upper end of the frequency range reproduced by the Eris Sub8. If you have enabled the onboard High Pass Filter, set the Low Pass Filter control to 80 Hz. Otherwise, set the Low Pass Filter control to the lowest frequency that your main monitors can reliably reproduce.

YMMV.

Hello. Thanks for response! My Sub does not take high level inputs. It only takes either RCA or Balanced XLR. My main speakers are Vestlyd V15C that go pretty straight down to 36Hz, and then smoothly rolls off below that. My speakers and the sub is the 2 best performing components in this setup, the amp is the lesser of the components, so I rather ditch the Sonos AMP for a real full featured amplifier than switching out the sub. I was just hoping to use the Sonos AMP since I already have it, and it does perform quite good for what it is. Thank you all for your time.
