2 different sounds

Installation Help & Advice Horn Kits
1

Ok, I thought I was imagining I had 2 different horn sounds. one seemed higher in pitch but not as loud. the other was the deeper train horn sounding. The other day i’m tired and driving down the grade and I lay into them, after a few seconds the high pitch turns into the low deep train notes. stayed like that even the next day when I just tapped it a few times. then back to the high pitched sound. I gave it a good 10 second blast and no luck in the deep notes comming back. All the hoses from the block to the horns are the same length so I know thats not a problem. do I have a bad diaphragm? its on an XL set up.

Thanks

yea seems like a common issue from the heat.

I called HB (can’t remember who I talked to but he was a great help) After work I checked all the fittings and drained the tank, just a small splash blew out but maybe it was enough in the lines. So far they are back to normal sounding.

Thanks for the Help.
