so the with the ports on the outside i get like 46hz of tuning..but it does not sound right..sort of it plays bettween 36-50 but when i get to about 50/62 ov the volume it starts to stink really bad from the sub..tried the other box works fine in full tilt.other box is tuned to 30hz tho..in this one something like a techno or dance songs sound fine but its not loud at all compared to before..i will need to play with teh portws..also would inverting the sub help?
