Description DENALI SoundBomb Compact Dual Tone Air Horn Inconspicuous styling, obnoxiously loud – that’s a contradiction you’ll only find in SoundBomb Horns. Don’t sacrifice safety for style, because our blacked-out Horns practically disappear once installed. The unique design of the compact Horn features a rugged molded clamp that mechanically mates the compressor to the acoustic unit. This makes the SoundBomb virtually indestructible even in high vibration applications.
