LM324 IC Based Subwoofer Low pass Filter Board

sub woofer low pass filter board on a black table surface — Subwoofer Low Pass Filter Board

Hi, hello friends lets check another interesting article of the Subwoofer Low Pass Filter Board circuit and its PCB layout. The complete project is available in the local markets. So i decided to reproduce the the PCB layout and built this low-pass filter board again.

So i spend some time with this board to get the PCB layout and components list. The complete project details are free to use. You can easily Download the project and use it.

LM324 IC Based Low Pass Filter Board

This subwoofer filter board is designed with an LM324 operational amplifier, so the components are cheap and available in any local market. The working voltage of this circuit is about 27V Dual supply. so you can use this low-pass filter board in high-voltage power supply amplifier boards.

There is two 104 Preset pots is mounted on the circuit board, This will control the bass of the subwoofer amplifier. Adjust both sections to control both Left and Right channel bass. In output section box type capacitors are used, this will achieve good audio quality in the output section. Use original LM324 for better result of this low pass filtering. All resistors are 1/4 wattage.
