I don't know why, but ever since I found the video of the Diaphone horn in Cape May, New Jersey on Youtube (link for those who haven't seen it), I've had a huge desire to own one simply because of the cool sound it makes
I have no clue what I'd do with it if I did have one (though I can think of some things - driving the neighborhood dogs crazy, scaring squirrels... ).
I've been trying to find more info on these things, but I haven't found a whole lot about them.
Can anyone here tell me more about these things?
