Beep beep!
Finally the horn mod is done!
Short history: Got 1 air horn kit. 11" + 9" end to end horns 40AMP rated pump. Pump actually only draws 19A @ 13.6v. Hooked up both horns. The small horn added "meep meep" sound. Took out small one, now it sounds ok but volume was just ok. Loud but not ear piercing or truck loud. Got another kit. Now just using a pair of compressors and a pair of 11" horns. Sounds just right
If standing in front of the vehicle it is approaching the threshold of pain, so individually they probably didn’t even reach 130db.

(The MP3 of the horns was recorded in a gigantic loading dock)

Air Horn
Griot's has an all in one piece Italian style air horn for $39.95, the compressor and horns are together. I saw it in the new catalogue they sent me. Supposed to be 139 dB in front of the vehicle. I'm sure you could find it on their website. It is a complet kit with relay, wiring, compressor and horns.
Here is the link:

I think I might get it on down the road.

My kit said 140dB and we all know how advertising is
That 'Italian' horn is definitely weak, it is rated at only 10amps. It's all about pressure and number of horns after all. Dimensions are kind of small too so it must be a meep meep. The compressors can also go bad and that would be it for the whole system, while a separate unit can be replaced, even to a more powerful one down the road. When playing with the locations of the horns 90% of the loudness was attributed to placement. With horns it simply has to be line of sight! Since it's a relatively high frequency anything and everything will muffle the sound. If you decide to put the all in one outside the engine bay it would probably pick up water and not get warm in the coldest of winter.
Anybody know if same rule apply to horns... double the power and double the horns = +6db. Double the horns = +3db?

I love eBay... all of this came from there with a total cost of about $100:

There've been some changes since I did that write-up - I moved to a larger air tank and the pressure is now up to 150psi.
They're LOUD.
(yes, I have to get a recording someday)

I get the error whether I hit the link direct from the outside world, from within the page, or from within a playback app like Winamp.

That way you'd have a sound file & vid of them.
I'm pretty happy with my Highway Blasters for now.

I have a mobile recording setup (Shure SM57, decent A/D converter, laptop, etc) but I'm just to lazy to haul it all outside and set it up with a mic stand and all.

im bidding on some hadley air horns... the lanyard pull type! i have an ARB compressor already... do u think it can power the horns? does neone know how many psi the ARBs hold. i dont imagine THAT much.... ???
You can push a stream of air at 100psi, but is the stream isn't big enough, then nothing will happen. This is why I use an external air tank.
The tank is loaded to 150psi and the compressor shuts off. When I hit the horn switch on the steering wheel, that opens up an air valve and the only thing stopping the flow of air to the horns is the 1/4" tubing (which is a limit of the fitting on the horns themselves). The amount of air being pushed at that point is FAR greater than the air compressor can provide at 150psi. The ViAir 450c is rated for 0.72 CFM (Cubic Feet per Minute) at 150psi, which isn't a lot of air.
So to tie this back into your asking about the ARB compressor, in short, I'd bet that it may not even sound the horns directly. I know that my ViAir won't, and the ARB is smaller than that.
Depending on the horns, you're going to want to look at doing a setup with a compressor, air tank, limit switch, etc.
Good luck on the auction!
