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

Product Information

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. But, using the Extech dB meter, we measured 118 dB at three feet for the Soundbomb, a good showing. From “E.Z.” (August 2015): “I have a working Stebel Nautilus Compact on my NT700VA. It sounds exactly like the Denali on your .mp3 file! A high-value alternative, one that’s really handy when space is absolutely at a premium, is the DENALI SoundBomb Mini Low-Tone Horn. Far more powerful than horns on most powersports vehicles, the SoundBomb Mini sill puts out 113 decibels of attention-getting sound but fits into a space less than 3.5 inches square and 2.5 inches deep. Moreover, the Mini is quite power efficient, meaning that many vehicles can handle the needed 5-amp load without needing an external power relay. And if that’s not the case for your application, a Plug&Play harness is also available.

Motorcycle manufacturers should definitely be doing better, or they should at least sell an accessory horn that has some guts. In fact, we wouldn’t be surprised to learn that the Soundbomb is made by Stebel or by ex-Stebel designers. Fitment Note: Add our BMW wiring adapter DNL.WHS.10100 below for a plug & play installation to BMW motorcycles. Original equipment motorcycle horns are notoriously awful, with a wimpy “meeep-meeep” type being way too common.

Step 5: Test the Horn

Lexus GX470 featuring DENALI D7 LED Driving Lights, SoundBomb horn, and DialDim Universal Controller The hardest part of dealing with the Nautilus or Soundbomb is mounting it on the motorcycle. These are big horns and most motorcycles have very limited spaces underneath the fairing or around the engine for mounting such a monster.

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 Soundbomb horn has a hefty 20 Amp draw. It measures about 138 mm wide, 116 mm tall and it’s about 88 mm deep. It also comes with a relay, but as always, we used a pre-made horn relay wiring harness (review). Sound Output The first failed due to our fault — some melting damage due to our mounting experiments, while the second failed after the third short beep, just like the other Nautilus horns we have tried over the years. The Denali™ SoundBomb was designed for those who want to be heard, but still want to maintain a stylish look.

I have Clearwater Glenda lights (review) on my bike, and with a little wiring, soldering, and Clearwater’s instructions, the Glendas go to maximum power if the horn is hit. A nice feature which is standard on the larger Clearwater lights, but not the Glendas.

Designed to be a direct Plug & Play upgrade from your factory horn, requiring no additional relay or wiring harness. UPDATE (August 2015): We initially mounted the horn shown in the photo at the beginning of this review and with the aluminum bar oriented as shown in the photos above. 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.”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. Product Specs Twisted Throttle said the horn was designed to be more reliable than the Stebel version, while still providing a loud air horn sound. 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.] 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.
