Hey, I have a box which exteranal measurements are 18 deep, 16 high 30.75 long with a port 14.5 high, 2 wide and 13.25 deep. I am an idiot with the tuning programs so can anyone tell me about what that would be tuned to, the subs are edk 12s.

well get the internal measurements and figure the volume of the box ((lxwxd)/1728) = volume of box....w/ that u can then to go a site like www.the12volt.com and use their port calulator and enter in the volume, the freq. u plan to tune it to, and the diameter of the port u wanna use and it will give u the port length

I already know the port length, 13.25...

I had to shorten my box by 1 1/2 inches so it thew my port calculations(that I got from trixter) off. My original port was 14.5 H x 2 w x14 deep the tuning with the box I had was 32 hz with that port. By shortening my box it threw that tuning outta whack, so I shortened the port a little bit, and now was wondering what the tuning would be, same height and width, just shortened to 13.25 with a different volume...again the box measurements this time internal are 29.25 l x 14.5 h x 16.5 D...thanks
