This is a low-pass filter. normally we use this circuit to make only bass. If we want to make the subwoofer, we need to use this circuit. This circuit only makes the bass. Other vocal or tone can’t be gotten from this circuit. We have to use this circuit as a pre-amp to our amplifier. Before the main amplifier circuit, this circuit has to be used to make the subwoofer amplifier, to get only bass.
