MDB creates harmonics of the frequencies below the MDB highpass frequency
(MDB_HP). The variable MDB_HMC describes the ratio of the harmonics
towards the original signal.

The MDB lowpass corner frequency (range 50...300 Hz) defines the upper cor-
ner frequency of the MDB bandpass filter. Recommended values are the same
as for the MDB highpass corner frequency (MDB_HP).

The MDB highpass corner frequency defines the lower corner frequency of the
MDB bandpass filter. The highpass filter avoids loading the loudspeakers with
low frequency components that are below the speakers
cut off frequency. Rec-
ommended values for subwoofer systems are around 5 (=50 Hz), for regular TV
sets around 10 (=100 Hz).
