How to make Pre Subwoofer Stereo with Powerful Amplifier, DIY Pre Subwoofer, New Circuit at home

 

Pre-Subwoofer with 4560D

This is a low pass filter circuit diagram to making a subwoofer. if we need more bass we can use this circuit to our amplifier to making a subwoofer. it’s an active subwoofer circuit diagram. if we use this circuit in our amplifier as a pre-amplifier then we can get the only bass from the amplifier. here in this circuit, we can input the audio as audio-R and audio-L and we can get the output as audio-R and audio-L. any kinds of sound we can input but we get the output only the bass.
