Horn speakers, often overlooked but integral components of sound systems, play a pivotal role in projecting and controlling sound waves. Their remarkable ability to extend the frequency range and enhance sound dispersion is crucial for a captivating listening experience. However, with a plethora of horn designs available, selecting the most suitable one can be a daunting task.

Taxonomy of Horn Speakers:

Compression Drivers:

These horns utilize a diaphragm to compress the air before it exits the horn, enhancing the driver's frequency response. A special type of compression type loudspeaker is a high-frequency (HF) compression driver where the frequency response extends up to the upper limit of the audible frequency range.

Exponential Horns:

Charactedrized by their conical or parabolic reflector shape, these horns direct the sound toward the listener, minimizing unwanted reflections and ensuring uniform sound distribution.

Consider Some Things About Your Horn Speakers:

Frequency response: 

Horn loudspeakers have a controlled frequency response that is optimized for applications where high SPL is required. They are often used in PA systems, industrial applications, and other environments where a clear, undistorted sound is important.


The dispersion pattern of a horn loudspeaker varies depending on the type of horn and its design. Wide dispersion horns can provide good coverage over a wide area, while narrow dispersion horns can focus the sound in a more concentrated beam.

Power handling: 

The power handling capability of a horn loudspeaker is important for applications where high SPL is required. A horn with high-power handling can handle the powerful output of high-end amplifiers without distorting or damaging the sound.

Environmental considerations:

Weatherproof horns are designed to withstand harsh weather conditions, such as direct sunlight, rain, and snow. If you intend to use your speaker horn outdoors, it is important to choose a weatherproof model that is rated for the conditions in which you will be using it.


The prices of horn speakers vary, but they are quite reasonable, like Vantom Audio brand offers very competitive prices in the international markets.

Shape and Size are Important Factors in Your Choice of Horn Speaker:

Shape and Size Influence Speaker Horn Performance:

Rectangular horn speaker models are particularly suitable for areas where the directivity of sound is important it gives sound over long distances. Also, the size of the horn speaker is directly proportional to the area in which the sound is distributed, the dimension of the sound, and its spread.

To navigate the intricate world of horn speakers and select the ideal option, consider these crucial tips:

Determine the Purpose: 

If you are looking to purchase a horn speaker for your public address system, it is a suitable option due to its pure and clear sound quality. This makes it ideal for public speaking, such as for minarets in mosques.

Frequency Response and Dispersion: 

Prioritize horns that match the frequency range and dispersion requirements of your application.

Amplifier Compatibility:

Ensure the horn is compatible with your amplifier's power output and frequency response.

Outdoor Use: 

If intended for outdoor use, opt for weatherproof horns that can withstand the elements.

When selecting a horn speaker, it's important to consider the size of the area that needs sound coverage and the desired sound intensity within that space. To achieve this, proper standards must be followed, including checking the diameter of the horn and the power of the driver unit of the horn speaker. It's worth noting that the higher the power, the higher the sound intensity. Additionally, the shape of the horn should also be taken into account. Rectangular and circular horns have unique features and uses. Lastly, the high quality raw material used in the horn speaker should be considered, as it must be able to insulate from external factors and resist rust.
