...as the smartest guy in the Chicago Horn Club. In certain quarters (figurative Bavarian castles surrounded by fortified walls, which are themselves surrounded by moronic peasants with torches and pitchforks, and with an overlord Raving Over Morons Yesterday) this may seem like a back- handed compliment, but the said peasants have better things to do. So as long as you don't try bossing us around, but we could use some direction at times ; )
The phase plug in the sym looks like a bisected "Hershey's Kiss", unlike the bullet shaped plug in the original, and you did state that this was so. This was presumably done to smooth the transition of the wave front as it exits the horn mouth, which may have shown some anomalies due to the bisected bullet? So would a Hershey's Kiss shape make a better phase plug than the usual bullet shape, or was this just a convenience in the sym to remove this as a point of contention?
I had no difficulty locating the vertical frequency divisions in the polar plots of the Le Cleach horn and the conical horn examples, they are at: 100; 1000; 10,000 and 100,000 Hz. These plots would seem to address the main performance point of contention here for the difference between the conical and Le Cleach horns.
Of all the horn families, the Le Cleach horn seems most like the tractrix horn, though the curve is slightly different, and there is that round-over at the mouth with the Le Cleach horn, where the tractrix curve by comparison ends at 90 degrees to its axis. That is if I have read JML'C's website correctly.
