wannabe

Excellent. I can't download the book, but I can read it on the site. I think I know where to find a copy. Thanks! Interesting story, I see the copy that google digitized was from U. of Michigan. I will also read the thread referenced. Do you think that PWK engineered the Belle, given the name, or another engineer that might still be around...I guess I would love to see a blog: "The Engineeering of the Belle Klipsch Loudspeaker".

Then it would be13x3 to 6x21 [39 < 126 sq in] and then 5.5x21 to 20.5x21 [115.5 < 430.5 sq in] If considered 2 horns the second compression would be 126/115.5 = 1.09. So, maybe it is just important that it is >1.0. Did Paul Klipsch describe the folded horn this way? Which papers or books are best to read? Horn A = 39/126 = 0.3095 throat to mouth ratio Horn B = 115.5/430.5 = 0.2683 throat to mouth ratio Are these ratios important? Sorry to ask such fundamental questions - haven't found the right materials yet. (also wondering about the accuracy of the drawings in this and other threads) I am considering some custom cabinets slightly scaled up from the Belle. I heard a pair of Belles in 1983 and thought they were great. I have always wanted that 'live presence', like someone is sitting there at a piano. Thanks again!

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.
