Dual-tone black Nautilus Compact Tuning air horn from Stebel.
Loud enough to convince other drivers that there's a derailed freight train barreling down on them. Don't press the horn button in the garage, it hurts! At 139dB it can be heard for almost 3 city blocks!
This is the WATER TIGHT version of the Nautilus Compact and is better suited for open operation on motorcycles.
The horn is specifically designed and
manufactured for custom tuning of medium and large motorcycles or on
automobiles (particularly suited for visible mountings). It has a sleek
- the visible face is completely black with a professional high
quality OEM finish able to resist 400 hours of salt and fog exposure.
The product is more water tight than the standard Nautilus Compact, in order to
better resist high water pressure spray washes and inclement weather.
The metal parts are powder painted black. It is supplied with a 90 degree female connector and a black rubber
tube (optional) to use for installations which particularly expose the horn to dust . Extremely compact (one single unit) therefore easy to install.
High and Low tone harmonized sound. 139 dB High Powered
Sound, more than 3 times (+10db) the power of a typical single tone OEM
factory horn. High audibility and sound attractiveness that only well manufactured air horns can
This is NOT a knock-off horn! This is a true STEBEL......... DON'T BE FOOLED BY IMITATIONS!
Includes a single M8 mounting bolt and nut, as well as a relay for providing a direct, high current attachment to the motorcycle's battery.
Per the manufacturer, this horn should be mounted so that the cylinder is vertical (with the horn facing down). There should be no more than a 15 degree variance from the vertical position. If it is not mounted per these specifications, then the horn may cease to function after a period of time.
If you own a 2003-2005 Harley Davidson motorcycle and horn relays are repeatedly failing, please visit your local dealership to upgrade your horn button under the Harley recall.
No wires, fuses, or bike-specific mounting brackets are included.
You may want to purchase the pre-made wiring kit & brackets.
Keep this in mind: sound energy doubles for every 3 points you go up in the decibel scale. It means that the Stebel Nautilus horn, which produces 139 dB of sound, puts out a LOT more sound than these popular horns:
- 800% of the sound energy of the more expensive 130dB FIAMM Freeway Blaster;
- 600% louder than the $140, 130 dB Pro Pad Mini Beast horn;
- 650% louder than the $179, 128dB Rivco dual trumpet horn.
You will not be disappointed - just make sure you wire the included relay properly, as replacement horns used without a relay don't get enough electrical current to be fully effective.
