i've read all the post on tuning a port but is there a formula i'm missing. i see people getting all these numbers but no calculations. I have 2 pioneer premier ts-w5000spl and want to put them in a vented(slot ported) enclosure. the specs on the sub are:

FS: 32.2

QTS: .320

QMS 8.599

QES: .332

VAS: 1.092 cu

RMS: 9.010

MMS: 348.42

BL: 37.378

Sensitivity: 89

The box is going to be pretty small in a wedge shape 13.5 " wide, 18" deep, 18 in height in the front and 16 in the rear. with the port on the bottom in the front. Can it be done with this size box.

You see people getting "all these numbers" because they're working it up in a computer program, for the most part. You should take the next step and do the same. Start by reading the WinISD guide stickied here and following along...which includes downloading the program.

But the very first thing you need to do is be able to figure cubic feet of your box size. This site has great box calculators. You've been a member from just about day one, so I imagine you know where everything is. You'll find more calculators in the guide and in the WinISD links that are referred to there.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
