[QUOTE="coolest user, post: 3552809, member: 581593"] I was looking at the PDF file for JL Audio 12W1's and I can't seem to figure out the math on the port. The port is supposed to be 33.75" long, and it has the "port extension length" listed as 14.5". The box is 17" deep. How did they come up with 14.5" for the "port extension length" ? My math tells me the "port extension length" should be longer than 14.5" though. I'm still learning, so maybe someone could explain to me how JL got their number... Here is a link to the file with the box size [URL="http://mobile.jlaudio.com/pdfs/8429.pdf"]http://mobile.jlaudio.com/pdfs/8429.pdf[/URL] . [/QUOTE]
