RageQuitForLife Posted February 6, 2015 Report Share Posted February 6, 2015 I just need some help with understanding how to tune the box to a specific frequency if my box is 36Wx22Dx16H which would make it 5.9 cubes and i want to tune the box to 30hz what do i have to do? I went on a few websites that calculate the port length, but when i put in my numbers my port length didnt make sense. For the port calculator i put the port would be 4 inch wide and 16 inches tall, and came out as a port length that is 25.7 inches long. I want to make a middle port between the subs, is the calculator using a side port and that is why my number is too big??? Please help i don't know what is wrong? thanks Link to comment Share on other sites More sharing options...
wil Posted February 6, 2015 Report Share Posted February 6, 2015 Maybe this will help you out, maybe I'm just wrong. But I would use Torres to tune your box: (Somebody let me know if I'm wrong) 2000 Ford Ranger XLT 4.0 NSB Group 34/78 SHCA Wires, Big 3 Pioneer DEH-80PRS Crescendo Symphony S1500.1 Pioneer GM-6100F SoundQubed HDS315 (2) Crescendo PWX6.5 (2) Crescendo FT1 Link to comment Share on other sites More sharing options...
hondakid1996 Posted February 6, 2015 Report Share Posted February 6, 2015 The port halves as it bends with a center port box. So each chamber would only get a 2 inch wide port. That's if you go with Wil's design. Link to comment Share on other sites More sharing options...
