The low filter of a Kenwood kr 9600 cuts of the frequency at 100 Hz. I would like to convert this filter to a subsonic filter. Can this be done? And if yes which resistor and capacitor should I replace and what should the new values be?
Cs3,4 (0.012u) form the hpf with the input resistance. Put a 0.1uF in parallel and it should come down to around 10Hz. This a 6dB/octave filter. Most rumble filters are higher order filters for steeper responses
