Did you see these cast horns?

[Old Guy]

Cerwin Vega, and frankly a step above junk. CV bought Heppner's assets, the Heppner drivers didn't handle much power, so just use two. These don't have an accurate horn flare and beam. 511 is 10x better horn. CV made these horns in about 4 versions, most had single throats, early ones had dividers like Altec. they went to a single divider then none.

Here's an early one in a Kustom cabinet.
