Thanks Timbo...my second horn dose have a deeper tone 2 it...I noticed when I hooked it up 2 battery & sounded them both off @ same time. It looks pretty much same design as stebel's, it is called a "Bad Boy"....other wise :agree: with you, it wouldn't really accomplish desired result.WS - I did a write up a while ago, I'll se if I can find it... I'm too lazy to re-type the whole explanation...
I work with acoustics and audio equipment pretty much every day of my life and went to school for it, so I know a thing or two about sound/audio.
If you want to, by all means, hook up two stebel's... but, you're really not going to gain that much in actual sound output. (approx 3dB-SPL, at most... which would be barely perceptible to most people...). If you're going to do it, I suggest buying a horn with a different "tone" or frequency. At least then, you'll get some subjective advantage from the two different frequencies either helping or playing against each other...
EDIT: HERE'S ONE OF THE POSTS
Torq has 2 Stebels hooked up as well as the stock horn.I have had mine on 4 a few years now & sometimes have laid on it a bit...never had any problems like that...embarrassing that would be...guess I should pick one up & have it with me just in case.
While were on the subject...I have had another air horn 4 a while with the intention of running two[hooked it up 2 battery once & both of them together sounds awesome.
I am not sure exactly how I should wire it up proper though...want both 2 work off same switch. Anyone have the know how 2 do this the right way? Appreciated :bigthumbsup:
