Denali SoundBomb™ Mini Electromagnetic Low Tone Horn 113dB Motorcycle Horn

Product Information

The Denali Soundbomb horn was made for Twisted Throttle as a replacement for the Stebel Nautilus Compact. Without getting into too much detail, we were told that TT needed to find a replacement for the Nautilus, for several reasons. At 113 decibels, the distinct low-tone sound from the DENALI SoundBomb Mini is over twice as loud as a typical 100 decibel disc horn.

The Soundbomb horn used in this review is the single unit version. There’s also a version with a separate compressor canister that can be remotely mounted. All of the Nautilus horns were mounted using a high-quality relay harness and each horn failed almost immediately. You can hear the sound of a dead Nautilus in the linked .mp3 sound file library below. Some motorcycle owners have opted for the huge Stebel Nautilus Max (review) or more likely, the Stebel Nautilus Compact (review) as their replacement horn choice.When I opened up the fairing, I saw that the tech connected the horn directly to the OEM horn wiring. When I installed the wiring kit, voila! It worked like a charm. So much for professional installation!

Sometimes, though, there’s no enough room under the hood for a one-piece horn, and that’s where the DENALI SoundBomb Split comes into its own. It’s the same basic horn as the SoundBomb Compact only with the 12-volt air compressor and the horn itself separated by a supplied durable hose. This feature allows installers to locate each component where they make the most sense, without compromising performance. Like the SoundBomb one-piece, the SoundBomb Split is available with a plug-and-play wiring harness that includes a water-resistance relay and high-quality wiring with pre-installed connectors. Motorcycle manufacturers should definitely be doing better, or they should at least sell an accessory horn that has some guts. Twisted Throttle also sells a wiring harness for it and various length/configuration coated steel attachment parts. I acquired all the kit I needed from TT, and the install went smoothly. As you can see from the photos below, the new mounting position puts the horn in the correct orientation and actually works better than the original mounting, because the wires can be semi-hidden behind the horn body.] It is recommended to not over tighten the bolt on the rear of the SoundBomb Mini. The horn should be secure, but should give way if rotated with pressure. Tighten the M6 nut to no more than 6.5 ft.-lbs. If the horn is too tight, it might not sound correctly.The SoundBomb Original is a powerhouse of a horn, producing an ear splitting 120 decibels of sound. If you want to be heard on the road or trail, this is the horn for you. Because the SoundBomb draws 20 amps of current, we suggest wiring directly to your battery using our plug-n-play wiring harness! However, Twisted Throttle (the Soundbomb distributor/retailer) sells accessory mounting kits for some motorcycles.
