Introduction
In the field of electronics, the subwoofer is like a blessing for audiophiles. It enhances the low frequency sounds that are responsible for the bass and thump. However, building a subwoofer requires a specific circuit that filters and enhances the low-frequency sound waves. And to achieve that, one of the most popular circuits nowadays is the subwoofer bass booster 4558 IC low pass filter circuit.
The subwoofer bass booster low pass filter circuit is designed using the LM4558 integrated circuit (IC). IC 4558 is a dual operational amplifier that contains two independent op amps. These op amp is used for a wide range of applications such as filters, amplifiers, oscillators, comparators, and more.

Why use LM4558 ICs?
The LM4558 ICs are preferred for subwoofer circuits because they have a higher gain bandwidth and slew rate which makes them suitable for audio applications. They have a bipolar transistor input stage and are internally frequency compensated for stable operation. The LM4558 IC is designed for low distortion, low noise, and high gain applications.
The 4558 IC subwoofer bass booster low pass filter circuit uses a combination of resistor-capacitor networks, op-amps, and inductors to filter and enhance low-frequency sounds.
The low-pass filter network filters out the high-frequency signals, leaving only the low-frequency sounds. The filtered low-frequency signal is then fed back to the input of the first op-amp through the resistor.
The potentiometer VR1 is used to adjust the gain of the amplifier. It determines the amount of bass boost that is added to the original sound signal.
