We probably don’t need to tell you what a horn does, but getting familiar with how it works and what makes the horns sound different from each other will help you in choosing the right horn for you.
There are two main types of horns in our kits: train horns and air horns. Train horns are classified by their low and deep harmonic tone as well as their typically higher volume. They also will always consist of at least 3 notes. Air horns, on the other hand, are generally higher in pitch and not quite as loud as some of our train horns get. Air horns can still be incredibly loud and some can be louder than some train horns, so it really comes down to personal preference on the tone to determine which one is better for you.
There are many factors that determine how a horn will sound, such as the shape and length of the bell, the material and components that it is made out of, as well as the amount of air pressure it is receiving. Many horns have multiple bells and are tuned to form a specific chord. Generally, the larger the horn and the more bells it has, the louder it will be. There are exceptions to the rule, such as our Shocker XL Horns that are compact but provide the volume of huge cast-metal train horns. This mainly comes down to the design of the sound chamber and the use of stainless steel internals. That's why it is imperative to get a horn made with quality materials and components.
The horns themselves are generally maintenance-free, but keeping your air system free of moisture and debris will ensure your horn maintains the intended pitch and volume. No matter what you do, your air tank is going to develop moisture, so draining your air tank on a regular basis will ensure that your horn sounds right every time you honk it.
