You just need a bigger compressor, a resevoir, and a big Buell or Stromberg
air horn from a fire engine. They're "tunable" and put out about 112-115db.
minimum. Loud enough? We took a scuba bottle, second staged it to 120psi
and put it in a canoe for Harborfest in Norfolk VA one year till the cops
ran us off. Or was it the black powder cannon that got us run off?...

I have to replace my compressor driven-12v horn. I would like to get as
much
"ship" sound as I can for 15 amps of 12volt. Any suggestions?
