Is it just me.? It is at 100Hz. To me it has a boomy feel. I took the parametric mid and set it at 50Hz and boosted a little and went wow that's what my passive P bass needs. I am not sure why they chose the voicing they did. I never use the bass control on that head. On my active Sadowsky I boost it at 40Hz and use the parametric mid to season as needed. End of rant.
