KleinnAir Horns 99 Dual Air Horn - Chrome-Plated Zinc Alloy

As loud goes they are the loudest ,most ear splitting at 140 psi. with a DB of over 150. If you do the math that is 1024 times louder than 120 DB. I have many other Vixen and Kleinn horns and for the price there my pick! Because of there short size the pitch is higher and penetrating .For years I have worked on protection systems for home and business, ultra high power horns are my choice by far.! Developing a perimeter or interior system triggered by a tiny remote pocket transmitter neutralize any one .PLEASE note ear protection for you and your people is a must if your are with in 500 foot . I mean good ear muffs !!!!!!! This horn is hundreds of times louder than any sold at CARQUEST or Auto Zone .Do your homework ,check the DB ratings for other horns then this one keeping in mind how to figure out DB sound levels , every 3DB higher is double so from 120 DB to 132 DB is 16times louder or from120 DB to 153 DB is 1224times louder. That my friends is the difference between this horn and most sold in auto stores .The US military currently uses high power sound on cargo ships to send pirates packing . In reading the one star comments on this product I wonder there IQ level .

ProsLOUD.Extremely annoying sound. (High Pitch)Fits in tight spaces.Made of metal.Comes with a solenoid.Can be connected to the factory horn.ConsSounds nothing like a train hornFor the price, the pros outweigh the cons in my opinion.Great little horn that should fit on just about any vehicle.I have included a video below as well with additional information.

I've seen people dump a load of brown stuff in their pants. Making cyclists take notice of their stupidity on the road with great results. Polite way to start a fight from 50 yards away with random people. Buy a pair for your mom. 120 psi gets panties wet.

These work great. Very loud. Work well with a 2 gallon tank and even work on 60 lbs or less. Will buy again when needed.

Probably great horns but there was no instructions in the box, so I couldn't figure how to hook them up. Call Kleinn they said get a compressor. Looked up compress on amazon and found one for 44.00 but found these same horns with compressor for 43.00 so I sent these back and order the one with the pump. Once again bad instruction and information on the ad.
