Channel routing and per channel equalizer on linux

Hello, I recently switched from windows to fedora kde. Everything goes smooth so far but I have a problem I am yet to solve. I am using 5.1 audio setup but unfortunately my reciever dont upmix stereo content to able to play on sound on subwoofer so I lack bass on every day content (music, video playback etc.). So, what I did on windows was on Peace GUI I just used channel routing on effect tab to route all channels to also play on subwoofer and I cut frequencies above bass range specifically for subwoofer so it doesn't play anything other than bass. But so far I am unable to find anything can achieve the same effect.

TLDR: I need a something to route all channels to subwoofer so it plays bass and I need per channel equalizer.
