i think im gonna make my own, and i used a calculator online, and i got the dimensions so that with the ports, i have about 1.8 cubic feet per woofer
The easiest would be to do a common chamber single slot port. Go to http://www.reaudio.com and use their box calculator. For two 12's with 1.8 cubes each, you'd want around 45-50 sq. in of port area and then fiddle with the dimensions until you get 3.4 cubic feet (net) with a port that's around 50 sq in. area tuned to your listening preference, anywhere between 32 and 38 Hz will be great on music.
