As rock ‘n’ roll displaced vocal groups and big band music in the 1960s, more output was sought from loudspeakers. The bass reflex enclosure helped to fulfill the new demands for power, clarity, and extended bass. Oswalds Mill Audio is famous for its extremely high prices for its products – well, the Imperia speakers are no exception.
Loudspeaker Enclosures & Horns: What They Do, How They Do It
In SonoAnalyzer OE, the only models that offer auto tuning are the database-backed ones, ie. These database-backed models produce answers very quickly but are also inherently rather limited. For this reason the auto-tuning option is not available on Online FEA models - in the current state of computer technology, multiple repeated FEA analyses are not suitable for a shared environment. However this is planned for SonoAnalyzer Pro where an analysis server can be dedicated to a single user. While they may introduce some colouration to the sound, their ability to project sound powerfully and precisely makes them an excellent choice for large venues and outdoor settings. Hence, the choice between horns and tweeters ultimately depends on the specific audio needs and personal preferences of the listener.
Horn Design (How do speaker horns work?)
This requires careful consideration of the driver’s specifications (such as its diameter and frequency response) and the design parameters of the horn (like its size, shape, and flare rate). Diesis Audio recently launched the Roma speakers, uncompromising speakers weighing 115kg each. A pair of 15″ dipole woofers, a 2″ midrange compression driver and a 1″ tweeter, 98.5 dB sensitivity, frequency response from 30 to 38,000 Hz and a maximum power input of 400 watts – everything looks great. The different types of loudspeaker horns include exponential horns, conical horns, tractrix horns, and hyperbolic horns. Each type has its own design and characteristics that affect sound dispersion and frequency response. For high volume and directivity, exponential horns could be a suitable choice, though they may compromise on sound quality.

Conical horns are known for their linear frequency response and minimal distortion. Navigating through the different types of loudspeaker horns can be a complex task, especially for the uninitiated. Each type of horn boasts unique features and characteristics, influencing the quality and dispersion of sound in distinct ways. This increased efficiency is why horn speakers are often the go-to choice for large venues and outdoor settings requiring high sound levels.
How Does The Design Of A Horn Speaker Affect Its Sound Quality?
When a cone driver moves forward it provides positive pressure to the atmosphere, exhibiting excursion. If the front and rear radiated energies are not separated from each other, each will cancel the other’s output because they are 180 degrees out of phase. HornWizard is not a complete horn simulator, but uses a simplified method to produce a close estimate of directivity and frequency response. First and foremost, it’s a “reality check” to see if particular specifications can be achieved within specified constraints. It also enables the user to see how different drivers work on the horn, aiding in the driver selection process. Five years of development, almost four hundred thousand dollars of retail – all this is Tune Audio Avaton.
FEA Engineering Design
Since the beginning of the twentieth century, horn acoustic design has remained one of the main speakers for speakers that can recreate the sound “in full growth”. Make sure to always listen to the speakers before purchasing, if possible. Remember, your personal preference is the most important factor when choosing a speaker system.
A speaker diaphragm (also known as a dome) in a compression driver can have a very small radiation surface. We could make the compression driver louder by increasing the size of the diaphragm so it will move more air, however in reality, this is often not practical. To understand how horns work, we need to focus on what is happening at the diaphragm of a compression driver or loudspeaker. In very simple terms, the volume of air in the horn provides resistance to the loudspeaker driver. This has the effect of improving the speaker efficiency (i.e. loudness in this case) and limiting the excursion of the speaker diaphragm at lower frequencies. Horn designs can include a variety of horn sizes and shapes and, for many, it is a mystery what these horns are actually doing.

By placing a horn in front of the compression driver, it is creating a much larger connection (or surface area) with the surrounding air. This has the result of amplifying the sound, as the radiating surface of the air coming from the exit of the horn is much greater than the radiating surface of the air from the diaphragm on its own. A horn amplifies sound by matching the throat impedance of the loudspeaker driver.

Essentially, the horn is an extension of the speaker driver, acting as a mechanical amplifier. Conical horns, as their name implies, have a straight-sided, cone-shaped design. Low frequency horns have to be extremely large, so folding the length of the horn makes the enclosure fit into a more practical space.
The curve of the horn wall is mathematically described by an exponential function, hence the name ‘exponential horn’. In the fascinating world of Finite Element Analysis (FEA), understanding the concept of boundary conditions is crucial. Horns are needed for such loud volumes and controlling the direction of the sound to ensure that you get the most loudness for your system. In some parts of the audience, you will not hear any or at least very poor high-frequency sound and in other parts of the audience, you will be overwhelmed with high-frequency sound. In the world of PA, this is really important as in a perfect world our entire audience will hear the sound well regardless of where they are standing in the audience or listening room relative to the speaker.
In general, horns are considered louder than tweeters due to their design. Over the years, I’ve found that the more I delve into the intricacies of orn speakers, the more I’m captivated by the science and the audible differences they bring to the sound landscape. Inside a new tool for eliminating microphone bleed in live performances via a simple analog design that's controlled by the artists on stage. Bass porting (or venting as it’s often called) can be used to increase LF output, though the output from the port is not in phase with the output of the pistonic pressure from the cone. Constant uniform psycko acoustic directivity coverage angles and throat from 1" to 1.5" on demand. X-shape, comparing to OS horn, have a true loading capacity allowing low x-over.
Fibreglass and composites are also used due to their ability to be moulded into intricate shapes, which can be advantageous for complex horn designs. In simple terms, a speaker horn works by managing the transformation of electrical energy into sound energy in a more controlled and efficient manner, enhancing both the volume and directionality of the sound. Additionally, the horn’s unique shape also controls the dispersion or directionality of the sound, ensuring the sound wave spreads out in a specific pattern. Essentially, it acts as an acoustic transformer, coupling the speaker driver’s energy more effectively to the air by matching the impedance between them.
