its 128 sq. in. of port //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.giffor 9.05cu' tuned to 30hz and using 60sq" of port i come up with a length of 13.5...if you need to add an end correction factor (port and box share a common wall) then add 1/2 the port width to the length to get a new length of 16.5" long.
Actually...5 x 12 = 60 in^2its 128 sq. in. of port //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
