See: the PipeWire Wiki:

Try setting the following in ~/.config/pipewire/pipewire-pulse.conf:

stream.properties = {
    channelmix.mix-lfe    = true
    channelmix.upmix      = true
    channelmix.lfe-cutoff = 80
}

Then restart PipeWire:

systemctl --user restart pipewire pipewire-pulse pipewire-media-session
