Did anyone build or buy the Corner Horn with the four internal drivers option?
How did you find it's sound?

It is spoken of in this early paper:
https://www.decware.com/DCHorn_whites.pdf

We read:
"When the horn is configured for commercial use [the 4 driver arrangement] the dynamics of how it functions are very different than when configured with the single 6.5" driver."

This makes me wonder if it sounds different.
