Giant Air Horn Made From PA Speakers
“It looks impressive and is twice as big as a 5-chime train horn,” says Dam. “I use a large propane tank for an air tank in my pickup and usually keep the pressure at 125 psi.”
All 5 air horns are made out of 3-in. dia. pvc pipe for the body and have 8-in. diaphragms made from in-floor house drains. The horn bodies measure 6, 9, 12, 18, and 24 in. long. The biggest horn has a 12-in. dia. public address speaker forming the flared end of the horn, while the smallest has an 8-in. dia. speaker. Dam made T-shaped brackets for each air horn and screwed them to a frame made from 3/4-in. dia. pipe.
The entire setup mounts on a single pipe stand. “One pipe slides over another pipe so I can rotate it in any direction,” says Dam.
