Both Kahlenberg and Airchime make comparable horns, however, I compared the
data between the two sites and at 100psi, the Airchimes put out 132db while
the Kahlenberg put out 122db. I think I was comparing similar horns. Prices
are not given. Interestingly, Kahlenberg gives a much longer audible
distance versus the Airchime. Airchime gives 900 meters while Kahlenberg
talks miles?
Perhaps tone has something has to do with it. It appears that the larger
Kahlenbergs have lower tones. Perhaps someone can give some scientific
insight?

a scuba bottle & regulator to supply air. It was very impressive.
