I just bought 2 Kicker L712, and I am trying to decide if I want to build a box or spend $150 and buy one. My question is how do I tune the box? The box size is 15.5H X 18.5D X 34W tuned at 38hz. I was going to make the slot 14H X 15.5 D X1.5 W and put a 7in piece on the end to make the L shape that kicker shows. I have made boxes before but not with the slotted port. I was going to put the ports in the middle of the box between the subs.
I hope you can help me if not thanks for your time.
