New Filter Subwoofer Circuit

If the audio device has a bass tone quality that is less kick, to overcome that is by adding an active subwoofer/crossover filter subwoofer so that the tone other than the low frequency will not pass to the power amplifier and the sound coming out of the speaker bass tone will be more enhanced.
