I've gleaned some basics from various websites (plus a few finer points here & there), but such seemingly disparate conclusions from two reliable sources left me wondering if I'd missed some glaringly simple horn principle. (Of course, the hit-and-miss educational system leaves much to be desired!) I know, I should download the McBean program; it'll have to wait until I can afford to add a PC-type computer.Does the throat area have anything to do with where the horn begins to beam? I've seen a few designs --mostly for 10" cones-- where the throat looked like the CD slot one would find in a 2" horn. Is this a similar diffraction technique?
