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

Product Information

Fitment Note: Add our BMW wiring adapter DNL.WHS.10100 below for a plug & play installation to BMW motorcycles.

Producing a massive 113 decibels of sound, the SoundBomb can be over twice as loud as a standard motorcycle horn! One main difference is that the compressor on the Soundbomb is attached with a clamp with two bolts. On the Nautilus, the horn or trumpet section appears to be glued to the compressor. The instructions note that “the horn should be mounted so that the cylinder is vertical with the horn facing down. There should be no more than a 25 degree variance from the vertical position.” Designed to be a direct Plug & Play upgrade from your factory horn, requiring no additional relay or wiring harness.

Step 3: Mount the DENALI SoundBomb Mini

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. But a webBikeWorld visitor who read the instructions more carefully than us (!) wrote to let us know we made a mistake. There’s nothing like going through all the trouble of mounting a big Nautilus — no easy task — and having it fail before you get the bike out of the garage. Oh well…

The horn has a higher pitch “European sports car” sound than the Stebel Nautilus horns or the Fiamm Freeway Blasters (review) or the Stebel Magnum horns (review) now mounted on the 2014 Suzuki V-Strom 1000 ABS (Blog), which sound like a loud car horn. Denali Soundbomb .mp3 The clamp is said to be more resistant to vibrations, which helps to improve overall reliability of the horn. Original equipment motorcycle horns are notoriously awful, with a wimpy “meeep-meeep” type being way too common. Although the Soundbomb looks very similar to the Nautilus, the construction appears to have more plastic than the Nautilus. But, so far it has proven to be much more reliable than the Nautilus in our experience. In other words, it works. So we cut a longer (18 cm) length of aluminum, drilled the two holes as noted below and re-installed the horn, this time in the correct orientation.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. The two of us spent quite a bit of time trying to find a good location to mount the Soundbomb horn on the BMW F 800 S. We tried to mount the horn behind the fairing and also in front of the exhaust pipes, on the side of the engine and even towards the rear, but nothing worked. Lexus GX470 featuring DENALI D7 LED Driving Lights, SoundBomb horn, and DialDim Universal Controller Some motorcycles horn circuits are not capable of powering this 5 amp horn. If your horn circuits' max amperage is less than 5 amps, or if you are unsure, simply add our plug-n-play harness to bypass the horn circuit and draw power directly from your battery. Also, add our standard relay as this is not included with the horn harnesses.
