@unfa there is a TAP LV2 port at https://github.com/moddevices/tap-lv2/
Maybe available in AUR, not sure..

Then extra eqs:
- caps (ladspa officially, lv2 port at https://github.com/moddevices/caps-lv2, maybe in AUR?)
- eqinox (from distrho-ports / juced-plugins)
- melmatch-eq https://github.com/brummer10/MelMatchEQ.lv2/
- kuiza (from artyfx)

airwindows might have some, not sure.
and there are a few mixer-like plugins around, they may have an integrated eq.
