Do you know the country of that horn?
It looks like 4 drivers are mounted together.

Children's toys. Now this is a subwoofer that will out sub woof all audiophile subwoofers.

Shock vibration testing equipment can be electrodynamic like this one or hydraulic. One I had an encounter with about 30 years ago, an electrodynamic model required an isolated "reaction mass," in effect a concrete slab to sit on weighing between 100,000 and 1,000,000 pounds. It was rated to put 14Gs into a test specimen from anywhere between 13 hz and 260 hz and a 14 ms impact of 20Gs as I recall. Proposed for installation in an R&D lab in an industrial park built on land fill in the South Bay area of Silicon Valley where the water table was 8 feet after 5 years without rain and they gave up looking for bedrock at 600 feet, this machine had the power to liquify the soil under a building and cause it to sink. One user who didn't understand it and bolted it to the concrete slab almost shook his entire building down around himself. Now that's what I call Titanic.

From time to time, I do some google picture searches. This is one of the interesting example:

Sorry, but the included text is all there was. I would ASSUME it was USA though being in a Popular Science mag.

I just thought it might raise a smile or two.
