It can filter down to subaudio ; the variable filter response is meaningfull at all settings ; its resonance can be anything from off, to natural, to more and more generous, up to the sweet spongy/instable spot, after which it starts to oscillate/contort lively... wide... Fixed or moving, flat or full, it is a lovely instrument part !
