Hey everyone. I just finish putting together my first DIY port box for my Dual Infinity Perfect 12's. But here is my problem. I designed the port thinking that I would put a plate amp on the back so I make the port to stop before it. My box is Outside dia 18"x16.25"x44" with a port of 16.5"x3"x55" so around 19~20 Hz 3/4" MDF but here is the problem. I put 3 180 degree turns in the port front firing with a front firing driver. I have put one together and the other I have not assembled yet. I am no longer using the plate amp so i could do a L-shape port now. Should I scrap the first box and buy another sheet of MDF or finish what I started with the wood already cut for the second box? I am not going to be pushing the sub very hard and from what I could figure the air speed on the port is going to be very very low, so should I even bother? Cost is a major factor so if it isn't going to be that big of a difference I am just going to finish it up the way I got it.
