How to figure out port.

[bad_trip 10+ year member]

I bought a pre-built ported box, and i know that you can specifically tune a box when it is built. I am wondering how i would figure out what my box is tuned to just by the raw information i have. i'm not sure on the exact dimensions of my box or port length, but that's easy to check. i would imagine that there is some kind of formula though? any help would be too cool.//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
