Hard to imagine anyone liking horn honk but generally this "sound" is not the fault of the horn but rather the crossover.
Well a better description is that in the old days, there was no way to design a crossover other than to look up values on a table or calculation.
While the calculations are correct, they are only correct IF one has a resistor as the termination and loudspeakers, especially compression drivers are not much like a resistor.
Usually one finds that there is a peak in the response related to the impedance peak at least on older horn systems and to me, it doesn't look like there is a lot going on now scientifically with horns except for some proponents like myself.
If the problem is indeed the crossover, how about going to multiple amps and a Line Level crossover like MiniDSP?
You can impliment nearly anything you can think of AND if you are willing to wade thru the math, even an FIR filter which has NO phase shift thru the passband. That's gotta sound interesting?
Depending on the crossover removed, you might even ADD a db or so to the overall sensitivity of the system.
Too much is never enough
My thought about "why" is this: Most horns with a single source at the apex are just too damn small. The bigger the horn, the better the horn. Unless you are Tom Danley and know hot to miniaturize them properly with multiple holes in the right places NOT in the apex.
"in the old days,"
"in the old days,", horns were often horrible. That's what I said. Don't blame it on the crossover, although, they were often iffy, too.
This is exactly 100% correct. I know, I have been through it !
