Loudest car horn without compressor

A horn is not only a sound-making device to call for your girlfriend while you’re waiting inside your vehicle. A horn is mainly used to warn others of the vehicle’s approach or to call attention to some hazard. Car horns are usually electric with sound levels not high enough to warn anyone in a city that uses cell phones or where people enjoy high volume music inside their cars.

Some customized automobiles use horns driven by air from a small electrical compressor to increase the sound volume. Sound levels are higher but the current consumption can lead to increase the size of the battery and additional installation costs. To overcome these problems, recently have appeared compacted horns easy to install in any type of vehicle with some special advantages:

  • No bulky air compressor/tank to mount.
  • Easy to install in all types of vehicles: one single bolt usually
  • No drilling into the roof of the vehicle.
  • Compact size, not the bulky one as the long trumpet type.
  • Low price.

Hope these benefits are enough to persuade you to install a compact horn without an external bulky compressor. Good luck. Below we present some of the best horns without compressor on the market.

Can you hear me? As the roads get busier and mood get shorter, it seems like everyone out there is trying to slaughter you. These horns are very loud when properly installed and for sure will get the attention needed in all traffic situations, with a current draw of 5.5 amp at 12V, similar than a conventional horn, but more potent. Besides, they are weather protected. Sound quality never fades, always it shows its consistency; however, some people have found that the paint could fade pretty fast if you are commuting normally on the highways.

After installing a set of Supertones, people know when they’re coming into your lane or about to pull in front of you. Not being the loudest ones on the market, they are pretty loud and a great upgrade. They fit in any type of car as long as you use the relay kit so you don’t pop a fuse.

Wolo, as their representative, guarantees the product and they will replace it in case they have a “bad” sound.

Stebel 11690019 – Nautilus Compact Mini Air Horn Black

it provides 2 great sounding tones in 1 compact tuned horn. The main feature of this horn is its breathtaking harmonized sound while being loud, at 139dB. You will have a difficult time finding a louder horn for the price. Ii has a compact size for easy installation built with a water resistant compressor that consumes only 18 amps at 12volts.

It can be installed in any vehicle with any 12-volt system (car, truck, motorcycle, golf cart, RV, bus, Rhino, Gator, ATV, boat, Hi-Lo, etc.) However, even with instructions and wiring kit, mounting this horn on a motorcycle may require some advanced skills.

When ordered the Nautilus Compact Mini Air Horn I strongly suggest you ask for the optional wiring kit which comes in the same box, unless you have at home different gauge wires and connectors.

With the cell-phone arrival, the vast majority of drivers need to “Be here now” and the Nautilus air horns are quite effective in that respect. THIS HORN IS LOUD! It does exactly what it says it does. It corrects what I believe is a major safety flaw on the most bike and some cars.

The horns are now glued together (compressor and plastic horn segment) so that separating them is impossible without destroying the plastic horn. It seems like its new marketing strategy is working as they are flooding the market due to their efficiency. A word of caution – there are a number of compact air horns on the market, obviously a cheap copy of the Stebel Nautilus but at much lower prices. In a direct comparison with the original, the copy is not as load as the original.
