Good by

Good and nice audio output. Good build quality and knobs a looking good total worth bass gain and frequency adjustment are working fine and till now I faced no complainta I'll repost it after using for few weeks or months. If you want a low pass filter for your subwoofer I prefer this actually this is not a low pass filter although you can adjust the frequency to low level so you'll get nice and clean bass.don't look at the other comments if you get a defective board there is a option for rep...
