deficiencies in the listening environment. The Punch Bass allows a
narrow band adjustment at 45Hz to help reproduce full range sound

Butterworth filter with a crossover point variable from 50Hz to 210Hz.
The crossover can be set to Low-Pass (LP) or it can be bypassed by
setting it to Full Range (FULL).
