The second time I ordered this board. After a small mod, the sound is very good. Thank you seller.
The delivery was fast. The filter itself is not as good as described. The lows are not deep, very much mid bass. I prefer the filter I used before. Is much warmer sounding and drives deeper. Very disappointing, expected a much better filter board.
After changing two resistors from the HP filter to 68 k, the sound improved massif.
