A speaker so loud it can kill you

There are trucks with those cursed back up beepers louder than a sonic weapon outside my office.

Too funny! Thanks. I needed a chuckle.

The size, shape and conditions of the room can be a huge factor. The most earsplitting thing I ever heard was a show by the 13th Floor Elevators at the Safari Club in Baytown, Texas ca. 1968. I know that PA system could not have been so very big and powerful, but man, did it pack a punch.

If that shook my brain loose it would explain some things that have happened in subsequent years.

Rock has made ear surgeons multi-millionares on a 20 hour week month schedule (no joke).
Beloved in Rochester, MN.

There are some speakers I would rather die than own. ;)

Well, maybe that's exaggeration.
