Clink on this link to read a thread about the 4520. The thread includes links to a bunch of different plans including upsized 18" versions .

( FWIW: The "search" engine on this site is pretty good at finding these sort of things . )

Here's a link to a German website with many LF horn designs. They have one of the better 4520 designs I've seen out there. It's metric, but there are plenty of conversion programs on the web which can be had for free (check CNET)
