I recently scored a pair of 2450H drivers with one small caveat: They came with 2360A horns attached.
What a pleasant surprise. I had no idea what to expect from these drivers, but since diaphrams for them aren't extinct I decided to give them a whirl.
Looking at them, you'd think the sound quality would be that of a PA at a football game or something. They are actually quite nice to listen to, even though I have them playing full range at a very low level, just turned the bass down.
The drivers and horns (well, throat adapters) both have consecutive serial numbers, so it looks like they've been paired up their whole life. Alas, the 2360A's can't stay. They are just overwhelming in size. Hopefully we can find a loving home for them
