Woofer Bass Amplifier Circuit Diagram. You ll probably find that this is the best sounding circuit. This subwoofer amplifier circuit consists of a tl072 low noise jfet dual operational amplifier ic1 and two lm1875 ic2 and ic3 power amplifiers.
Transistors q4 to q7 form the output stage. Since no ics are used the circuit is very robust and can be easily assembled on a general purpose pcb. This tda2030 amplifier can produce 14watt output and this can be increased upto 30watt by using another tda2030.

Hi friends in this video i am showing you. This is the circuit diagram of a fully transistorized sub woofer amplifier that can produce an output of 100w there are seven transistors including four in the output stage. The bass boost is basically just a low pass filter and it removes most of the noise not taken out by the decoupling capacitors. Subwoofer amplifier circuit diagram.
