well came up with a 5" wide port 19.5" high and 26" deep tuned to 31.46, 7.77 net volume and 1.99sq ft of port area wich comes to 12.55 inches of port per foot sound good???? Anyone? lol

well thanks for the advice but i am going with the optimal ported specs on the website, the box is a little complicated but I imagine it will sound great
