2nd Gen Non-Engine/Transmission Hadley Air Horns...square or round?

[Devil Black Diesel]

I'm looking into these Hadley Air Horn kit's but I'm not sure if I should get the round horns or square horns? What's the difference? Which horns are louder?



Here's the link:

I'm looking at the kit with the 26" and 29" horns.

For those of you that have these mounted under your truck did you face them forward or backward? Did you put both horns on the same side of the truck or did you mount one horn on each side?



I imagine these will do the job and sound like a big rig?



Thanks for the info.

I had a set of round under the hood of my 98 Ram pointed to the front. They were loud enough (for awhile anyway). Then I bought a set of FIAMM 28" round trumpets and installed them where the factory fog lamps go. They were loud!. As for square or round, it is more cosmetic - go with what you like better.

Wow, that's a very clean install. How long could you pull the trigger before you would run out of air? How big was that tank?



Thanks

Just incase the page is down again

I used a shell of a fire exinguisher and machined a bushing for the top and plumbed in the pressure switch. I then purchased a set of 28" Fiamm Air Horns from Ebay and mounted them in the factory fog light holes.

im not sure which ones are louder..... where are you wanting to mount them? member TReed has a nice set of square hadley's mounted on his roof...

I'm looking to mount (hide) them underneath my truck - probably one mounted on each side underneath passenger and driver facing forward. I think the square ones will be easier to hide as long as I have a 8 1/2" wide gap to hide the square horns.
