Resonant bass boost coefficient x. Six 14-bit registers are used as the filter
coefficients to specify the bass boost characteristics. The six coefficients are k1, km,
a1, a2, b1 and b2m. A software program is available for users to generate these six
14-bit coefficients by entering the desired centre frequency, peak gain, sampling
frequency and shape factor (default flat response).
