Can someone please explain to a noob the math for the Belle folded horn? I know this thread is a bit old, but seems like a good place to ask about the dimensions calculations.
In particular, I don't understand why the horn constricts to 2.75in after the throat is 13x3in, but maybe I am not calculating the volume or crosssection correctly - or, more likely, I just don't have a clue. Also, it seems like the compression ratio with a K33 is about 4:1, that seems high.
Maybe I just need pointed to a primer. Y'all seem to have a great community here and I have always admired Klipsch, the man, the company, and the speakers. Thanks for all your posts.
