SoundBomb™ Split Dual-Tone Air Horn

DENALI SoundBomb Split Horn — Loud, Rugged, and Built to Be Heard

The DENALI SoundBomb Split Horn is made for riders who want serious sound without sacrificing clean installation. Producing a massive 120 dB at 3 feet, it is 4 times louder than a standard motorcycle horn and twice as loud as a typical car horn — giving your bike the authority it needs when traffic gets too close.

The compact blacked-out design keeps the look clean and discreet once installed, while the powerful dual-tone blast makes sure you are heard when it matters most.

Flexible Two-Piece Design

Unlike a one-piece horn, the SoundBomb Split separates the compressor from the acoustic unit. This makes installation much easier on motorcycles with limited space, allowing the components to be mounted in different locations behind body panels, under fairings, or inside protected areas of the bike.

A 48-inch heat-resistant air hose connects the two components, so you get full sound output without being forced into one mounting position.
