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.
