Quad Horns - Horns Only

Loud and obnoxious can be a good thing

Received my horn set packaged well and once installed they are exactly what I wanted. A good blast and everyone knows you are there.

Good Price, Good Sound

I bought just the quad horns separate, for a future install on a vehicle. First off, they sound good, but I did a quick mod, which, to my ears at least, improves it considerably. I removed the shortest bell, and plugged the hole. While I know it won't be a perfect match, to me it now sounds much like a K3L/K3H horn, which is easily my favorite train horn. To anyone planning on doing something similar, you do not need much air pressure. Around 20 psi at a low CFM rate, is enough for a beautiful tone(and still quite loud compared to any normal vehicle horn). Too much air majorly degrades the sound, and I'm sure is hard on the horn. Time will tell how it lasts for me, but after initial testing, it sure looks(and sounds) good to me. Based on my experience so far, I would definitely buy again.

Quad Horns

These horns are definitely LOUD and sound just like a diesel train's horns. I mounted them under the hood of my Ford F-150. For best results, ensure that you mount the horns so that they point downwards, allowing moisture and debris to drain or fall out. The horns are securely mounted to the frame of the truck. The relay plug and connector was sealed with RTV to reduce the effects of moisture and corrosion on the connections. These are my 3rd set of train horns and my only set of quad horns! I would recommend these horns to anyone who needs a reliable, loud warning system.
