Hey everybody I was wondering if you all would be able to help me with my search. I am looking to build a transmission line speaker. I have been searching the internet for a kit or plans for a nice TL design. The only one that I have found was one in the Zalytron catalog. However, the focal drivers appear to be no longer made as the project is a few years old. Has anyone come across any TL designs on the internet or elsewhere(exclude the one in Mr. Weem's speaker book). Or does anyone have an ideas on one they're building, or have built that they would like to share.
