I haven’t tested it yet. But I don’t know if it sounds good or not, because I made this box with a slotted port and I don’t think that any one has made an ABC box with slotted ports before. But I will test it in the next few days. Hope that it works.
I know that V1 is tuned to about 31.5Hz. And V2 is tuned to about 63Hz. I think that I need to tune it down some more V1 should be around 25Hz
