Product FAQs
Q: Which is your loudest horn?
A: The Bully Series of Horns is our loudest at 130db’s (decibels). The Bully Series offers two mounting options:
- Roof Mount horns – H00910 series
- Under Hood horns – H00640 series
Q: Which Hadley horn has the deepest pitch?
A: The deepest sounding horn Hadley offers is the 37″ round bell horn (also our quietest horn at 115 db’s). For our loudest horn (at 130 db’s), choose from our Bully Series.
Tip: The pitch and loudness of an air horn varies depending on its length – longer horns have a deeper pitch and are not as loud. See our horns.
