New enclosure=I need help!

[wlmrs 10+ year member]

If anyone can help me I would greatly appreciate this.I got all my cuts done today for my new 5+ cu.ft. slot ported box except for 1.Since I'm an spl fanatic I will be tuning this box to 40hz,I know it's high,I know I know.External dimensions are:33.5 WX13.5 HX26 D.The only cut that was not made is the port,Does any body know how wide and long the port should be?Normally I get this information from accelerator-pedal.com but that site will hasn't worked in a couple of days.This is my last step before I start putting this bad boy together and yes I will post pictures as soon as I finish.Oh yeah I'm using 3/4" mdf.

I don't know if this is right,but this site says my port length should be 7.45 inches????http://www.carstereo.com/help2/Articles.cfm?id=31 5.33 cu.ft./40Hz/ Port will be 4" wide/12" high. 1 port.Can any tell me if this sounds right??

Yea it's pretty close, that gives me 42hz tuning in BBP6, a port that large is liable to be effected by positioning anyway so it can change slightly in the car.
