Stebel vs. Bad Boy Air Horn

I read a bunch of threads on here about the two horns being almost identical in look and sound. The Stebel Nautilus is German made and the Bad Boy by Wolo is made in China.

I purchased the Stebel Nautilus Compact Horn and used the supplied relay and mounted it close to the master cylinder and I have to say that I was not impressed with the sound...very wimpy. I actually received a lot of negative comments from friends about it. I thought that it was probably due to the location I placed. I noticed that the Stebel website lists a Nautilus Compact for Truck and a slightly different one for Motorcycles. My Stebel looks exactly like the Bad Boy compact air horn. So, I was curious about the Bad Boy by Wolo because I had one in the past and thought I should give it a try since I could pick one up right down the street at my local Harbor Freight. The Bad Boy blew away the Stebel...no pun intended. The sound is much much louder and stronger. I even kept it in the same location.
