Deep Air Horn?

[Willys]

I'm thinking about getting an air horn now that I have a York OBA mounted on my truck. My brother has Grover 1600 somethings, and they're loud enough, but not nearly deep enough for my taste. What type of horn will have a deeper tone? a longer one? single horn versus double?



oops, seems I posted this in the wrong forum. How do I delete?

Just like a brass instrument, the longer the column of air that's vibrating, the lower the note.

Also the larger diameter the pipe the lower the tone as well. So for the lowest tone you need a long, large diameter trumpet, or maybe it's a tuba.

That's what I suspected. Middle school band was a looong time ago... My friend played a trombone that had a trigger to allow an octave or two lower... it made a longer column. So the next question is... what trucks/equipment would use a 30" air horn? Any big rigs have factory looooong horns? I'm trying to find a big truck junkyard in the Atlanta area too if anyone knows of one. I need a tank as well.
