When stereo came in, corner horns went away.

It wasn't a horn, it was a bass-reflex.

If you had ever seen one, you would know better.

Paul Klipsch was (is?) famous for his corner horns.

"The Klipschorn is the only speaker in the world that has been
in continuous production, relatively unchanged, for over 60 years."

But the most impressive corner horn demo I saw was the Cerwin-
Vega room at an AES convention in LA in the 1970s. They had
an "M" cabinet which looked like a largish column speaker. But
when positioned just right facing into the corner, it would flap your
pants legs at 20 ft. This page has a drawing of the appliation...

C-W were also showing a 12-inch(?) driver which they would
plug directly into the 120V power mains outlet in the hotel room.

There were rumors that C-W cracked some plaster and had to
pay the hotel for repairs. And other rumors that the JBL demos
in another room down the hall, were reproducing such realistic
gunshot sounds (thanks to their 075 ring radiator tweeters, aka.
the "acoustic laser") that the LAPD was called out to investigate.
