Subwoofer booster circuit is used to enanching or boosting or increase the subwoofer amplifier, but it also can improve the quality of the bass sound on an amplifier or High Power Amplifier. Subwoofer booster circui / bass enhancer circuit based on the IC 4558 and TL074 or commonly known as IC op-amp , its suitable to be an boosting in subwoofer system, which together with some components.
For this subwoofer booster / enhancher circuit using voltage of 12 V + , 12V - , and ground. To be in accordance with the power of the speakers and amplifiers , the Subwoofer booster circuit / subwoofer enhancer is also equipped with a subwoofer volume setting on the R9 and R12 use 20 K ohm trimpot. Issued a circuit of subwoofer output is quite high , making it suitable for some speakers.
