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….

There is no such setting in Sonos’ software, sorry.

The bypass operates as soon as there is even a blank plug inserted into the Sub out on the Amp, and this cannot be avoided.

If your Sub has high level inputs that can take speaker level signals, you can wire the speakers terminals of the Amp to it, exactly as the main speaker pair is wired to the Amp, and have the speaker pair wired to the speaker out jacks on the Sub. If the latter are not there, wire both Sub and speaker pair to the Amp speaker terminals.

    So you do not need a sub?

      I do need a sub to cover 18-45Hz and to smoothen out the bass coverage in the room. But my main speakers are 15 inch high efficiency coaxial, so I want them full range.

      The Sonos Amp can be set to pass all signals above 50Hz to the main speakers; that should allow them to deliver full value without having an overlapping low bass presence with the sub that may cause more issues than it addresses.

      Hello! I tried setting it to 50Hz, and it just cuts off too much bottom. It’s just really wierd to force you into using high pass filter just because you connect a sub. This amp is pretty much useless to me now.

      The amp is “useless” only if your Sub does not have speaker level input capability.

      I am curious: how low do those speakers go in a +3/-3 dB range?
