I do not know what to tell you my friend, current EV drivers for paging horns that I found in the parts express catalog go down to about 350 hz but they do state how high they go.Than at the atlas sound site they do not make the 422 driver any more, but a 30 and a 40 watt driver, the 30 watter goes up to 3900 hz and the 40 watter hits 4100 hz, so I guess Kustom back than had no choise but to use a 5k cut off driver for a non- pro type thread on horn.
Just imagine that early kustom gain hiss coming out of a driver if it even went up to 12khz!
