at 70 degrees my stock horns sound good. The colder it gets, the worse it sounds. At 18 degrees this AM it has only a pitiful sound that sounds like someone strangling a cat (not that I have done that). I know when it warms up, it will return. What gives????? Do they all do that? I have a set of air horns, but they are so loud I do not want to use them in day-to-day traffic.

 

I never check if the horns get weaker in the cold but can imagine they do because the diaphragm is probably frozen. Lay on them for a while and see if the vibration doesn’t loosen them up.

 

I already tried that, it blew a fuse. When the temp gets back to about 40, they will honk again instead of squeeeeeeek! I have thought about going to the junk yard and getting a set of caddy horns (now there is a honk!)

 

If you knew they were loud and obnoxious when you got them in the first place...what's the deal w/ using them in day-to-day traffic...like Emeril says..."Kick it up a notch"

As for the horn question, not that know what's in there, but it definately has something to do with how the metallic parts are contracting w/ cold weather, it could be that some of the gaps/seals open up a bit resulting in sound getting scattered rather than channeled through the horn trumpet...

There are 4 of the air horns from 14" to 19" with a 5" bell. They sound like a train when they blow. If you are standing outside, your ears feel the pressure of the sound. I would not want to use them in traffic, but they are fun.

 

You're just a nice guy I was driving down the street the other day and heard a train horn and I was like...they don't have RR trax for miles from here...then I saw a jaloppie caddie roll up on side of me and give the great american one handed salute to some old lady as she pulled into a gas station...he must have been a good 100 yards away from me when I heard it the first time...
