Dual-trumpet black Nautilus air horn from Stebel.
Stebel's Nautilus is an innovative signal horn! It has the advantages of an
electromagnetic horn with the nostalgia of an air horn, with two separate dual trumpets! This horn is economical,
practical and easy to install like an electric horn, yet features the
power, reliability and uniquely pleasant tone of an dual air horn. It has a
modern and aesthetically pleasant design which gives origin to its name.
In addition, this design will be highly appreciated as an 'open view'
accessory. It is an easy to install air-horn which is
compact and LOUD!
In few words: powerful, practical, compact,
Stebel's Nautilus has its dual trumpets side by side pointing down and is 1" deeper than the Nautilus Compact and Nautilus Compact Tuning.
The NAUTILUS horn features compact
space-saving engineering that no other
twin tone air horn in the world can offer. It is very fast and easy to
install because it requires only ONE fixing point (and a single
electrical connection). NO TUBES are necessary! The excellent sound
output is INSTANT thanks to an incorporated perfectly balanced air jet
system. Its incredibly reliable motor withstands more than 50.000
continuous action cycles!
The Nautilus has a beautiful "DESIGN IN ITALY" design which makes it
perfect for openly visible applications.
If you need a slightly smaller horn then you may want to consider the Nautilus Compact series. The trumpets on this standard Nautilus point straight down.
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.
No wires, fuses, or bike-specific mounting brackets are included.
You may want to purchase the pre-made wiring kit.
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.
