Subwoofer Filter NE5532 Schematic PCB

On this occasion, I will share the circuit for subwoofer filters in this subwoofer filter different from the previous filter or subwoofer module. In this circuit only use 3 pieces of Op-Amp IC which we usually encounter in tone control circuit, active crossover, a filter circuit, another preamp circuit that is IC NE5532. This IC is very popular so I will apply it to this filter subwoofer circuit
