i am new to building boxes, and i own all the tools to do the job, i currently am looking to build a ported box for my (2) 12" Jbl GTi 1200 subs that have a minimum requirement of 1.75 ft3 per sub so i am looking to build around 4ft3 box with the subs together with a little extra space for ports... i want the box to be tuned to around 35-40Hz.. could someone here give me dimenisions on the box and a web site that shows you how to build the box with the vents?
