    porting? is there a formula?

    anyone be able to give me something like a formula to tuning boxes. like how i would figure in the lenght,width,height, and sub freq. to come up with a port size, or length. if u need specs, say a box for my MTX 5500 thunder sub. 6.7 mount depth, and a box width 14 1/4, length 20 1/2, height 14 inches. total of around cubic ft. and 38 Hz reccomended tuning. (that internal volume, not including the 3/4 wood)
