Subwoofer Low pass Filter Board

Hi, hello friends lets check another interesting article of 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 Downloads the project and use it.

LM324 IC Based Low Pass Filter Board

This subwoofer filter board is designed with LM324 operational amplifier, so the components are cheap and available in any local markets. 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.

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