Can anyone recommend some good websites or even books that would give me a great primer on horns? I am a complete agnostic when it comes to them & it's high time that I start to learn more about them. Thanks.
here you are, Mr. M.
While not exactly what you might be looking for I bet the biography of Paul Klipsch would probably be interesting.
Try the klipsch website and especially the forums. A lot of knowledgable hornies there.
