When it comes to speaker design, there are few concepts as fascinating and widely debated as the tapped horn. This innovative design approach has been gaining popularity among audio enthusiasts and professionals alike, promising unparalleled sound quality and efficiency. But what exactly is a tapped horn, and how does it work its magic?
Understanding the Basics of Horn-Loaded Speakers
To fully appreciate the tapped horn concept, it’s essential to understand the fundamental principles of horn-loaded speakers. In traditional speaker design, a driver (such as a woofer or tweeter) is mounted in an enclosure, which is typically a box-shaped cabinet. The driver produces sound waves, which then radiate from the enclosure into the surrounding air.
Horn-loaded speakers, on the other hand, use a different approach. Instead of a traditional enclosure, the driver is mounted at the narrow end of a flared horn-shaped tube. This horn serves as an acoustic impedance matcher, gradually increasing the area of the sound wave’s propagation path. This allows the sound wave to transition from the high-pressure, high-velocity environment near the driver to the low-pressure, low-velocity environment of the open air.
The horn’s flared shape achieves several key benefits:
- It increases the efficiency of the driver by reducing the back-pressure and allowing the driver to produce more sound pressure level (SPL) with less power.
- It helps to couple the sound wave to the air more effectively, reducing losses and increasing the overall sound quality.
- It provides a more even dispersion of sound waves, reducing the impact of room reflections and resonances.
The Tapped Horn: A Game-Changing Innovation
The tapped horn takes the traditional horn-loaded design to the next level by introducing a secondary opening, or “tap,” along the length of the horn. This tap is typically located near the midpoint of the horn and serves as an additional outlet for the sound wave.
The key benefit of the tapped horn design is its ability to reduce the overall length of the horn while maintaining its performance. This is achieved by allowing the sound wave to exit the horn through the tap, reducing the distance it needs to travel before being released into the open air.
The tapped horn design offers several advantages over traditional horn-loaded speakers:
- Compact size: The reduced length of the horn makes the tapped horn design more suitable for smaller rooms or applications where space is limited.
- Improved efficiency: The tapped horn can achieve the same level of performance as a longer traditional horn, but with less power and reduced losses.
- Enhanced sound quality: The additional outlet for the sound wave helps to reduce resonances and coloration, resulting in a more accurate and detailed sound reproduction.
The Science Behind the Tapped Horn
To fully understand how the tapped horn works, it’s essential to delve into the world of acoustic impedance and wave propagation.
When a sound wave is produced by a driver, it travels through the horn as a pressure wave. The horn’s flared shape serves as an impedance matcher, gradually increasing the area of the sound wave’s propagation path. However, as the sound wave approaches the end of the horn, it begins to experience a significant increase in back-pressure, which can lead to losses and reduced efficiency.
The tapped horn design addresses this issue by providing an additional outlet for the sound wave. As the sound wave approaches the tap, it is partly diverted through the tap, reducing the back-pressure and allowing the sound wave to exit the horn more efficiently.
This diversion of the sound wave has a profound impact on the acoustic impedance of the system. By reducing the back-pressure, the tapped horn design creates a more even impedance curve, which allows the driver to operate more efficiently and produce a higher SPL with less power.
Tapped Horn vs. Traditional Horn Design: A Comparison
When comparing the tapped horn design to traditional horn-loaded speakers, there are several key differences to consider:
- Length and size: Tapped horns are generally shorter and more compact than traditional horns, making them more suitable for smaller rooms or applications.
- Efficiency and power handling: Tapped horns can achieve the same level of performance as traditional horns, but with less power and reduced losses.
- Sound quality and accuracy: Tapped horns are designed to reduce resonances and coloration, resulting in a more accurate and detailed sound reproduction.

One of the most exciting applications of the tapped horn design is in the field of subwoofer design. Tapped horn subwoofers have gained popularity in recent years, offering an unparalleled level of performance and efficiency in a compact package.
By using a tapped horn design, subwoofer manufacturers can achieve a number of benefits, including:
- Increased efficiency: Tapped horn subwoofers can produce the same level of SPL as larger, more traditional subwoofers, but with less power and reduced losses.
- Improved sound quality: The tapped horn design helps to reduce resonances and coloration, resulting in a more accurate and detailed low-end response.
- Compact size: Tapped horn subwoofers are often smaller and more compact than traditional subwoofers, making them ideal for smaller rooms or applications.
