This is a low pass filter circuit diagram to making a subwoofer. If we use this circuit in our amplifier as a preamplifier then we can get the only bass from the amplifier. If we need more bass we can use this circuit to our amplifier to making a subwoofer.
How does the subwoofer filter works.
The outputs are then connected to the final amplifiers of the battelite boxes. Opamps a6 a7 function as the lowpassfilter a8 as the output amplifier for the subwoofer signal.
