Leslie Tyfons 300 and 425. Bigger than 20 train horns

We aren’t really sure what purpose a horn of this magnitude could possibly serve outside of being mounted to a train, but this hobbyist has his horns set up to blast on a trailer!

With the simultaneous honking a Leslie Tyfons 300 and 425, this enthusiast has what he claims to be louder than the blowing of twenty train horns all at once.

Out in the middle of nowhere, the horns blast at 106 and 64 Hz in this clip, loud enough to blow some unprotected ears out and probably shake a house to its foundation.

Check out the 800-pound setup fueled by a 120-gallon tank of compressed air that lets these babies rip! Just imagine a train horn prank using these giant noise makers!
