The lowest possible setting is an electrical 4th order, tuned for S12 PRO at 36 Hz, and for M-F3A FS at 55 Hz.
These filters are always enabled.
All frequency steps above the lowest option correspond to an acoustical 6th order Butterworth filter.
These additional values are:
-
S12 PRO: 48, 50, 53, 56, 60, 63, 67, 71, 75, 80, 85, 90, 95 and 100 Hz.
