Loudspeaker designers instead came up with the idea of an infinite baffle, which is little more than a sealed box. Until recently, it seemed impossible to beat the price of Magico Ultimate or Vox Olympian, but Cessaro with their Omega I speakers broke even these barriers. Acoustics for millionaires weighs 4.5 tons (four and a half tons is not a typo), claims 116 dB of sensitivity and is equipped with eight speakers, including 16 ”woofers. Each of these materials has its own sonic characteristics, so the choice largely depends on your personal preferences and the specific requirements of your audio system. Plastics, particularly high-density ones, are lightweight, versatile, and resistant to moisture, making them suitable for outdoor or portable speakers. They typically produce a neutral sound but may not offer the same level of audio fidelity as wood or metal.
Conical Horns
The speakers are equipped with a 1.25” textile tweeter, a 6.5” AlNiCo magnetic system midrange driver (both drivers are enclosed in horn design) and a stunning 18” woofer. 98 dB sensitivity, frequency response within 19 – 30,000 Hz, as they say, the impossible is possible. The flare rate, or the rate at which the horn’s width expands from the throat (the section closest to the speaker driver) to the mouth, also plays a crucial role.
Lost In Translation? Pro Audio Has A Language All Its Own
In the realm of audio technology, the term 'speaker distortion' often conjures mixed feelings among enthusiasts and novices alike. Imagine standing in the audience at a concert where there are design problems with the speaker horns where it is “beaming”. This meant that almost all of the earliest car horns used purely mechanical means of making noise.

For the square horn design profile the sub programs exp_horn and cat_horn output dxf files for manufacturing the horns. The flat sheet fabrication plot is for manufacturing a square horn from sheet metal or plywood. The red solid line is the wide sheet for the top and bottom and the solid line is the narrower sheet for the sides.
Also known as hypex horns, hyperbolic horns are an advanced design that attempts to combine the best aspects of the other types. They have a hyperbolically increasing rate of flare, which theoretically provides an even frequency response, high efficiency, and minimal distortion. This article aims to demystify the intricacies of loudspeaker horns, delving into their function, the advantages of horn-loaded speakers, and how different designs can drastically impact sound quality. A horn will start expanding, starting from the throat and end at the mouth. The speaker will be connected at the throat of the horn, and radiate sound at the mouth of the horn.
The horn addresses this issue by collecting these initial sound waves and channelling them into a focused beam of sound. There are many horn profiles on the market and usually, when purchasing a horn, you will be given an indication of what area of sound it will cover and how well it will perform. At home, bookshelf speakers do not require such loud listening levels, therefore they do not need a horn, nor will they benefit from a horn.

The first baffles were nothing more than a flat surface for mounting the cone driver, its purpose being to isolate front radiation from rear radiation. The larger the baffle, the lower the frequency range the cone driver could reproduce (within its other limits, of course). The selection of a horn loudspeaker involves a careful assessment of several factors, such as frequency response, efficiency, directivity, material, size, aesthetics, cost, and brand reputation.
AudioHorn is a horn speaker design office and manufacturer located in France.
HornWizard has been developed to introduce systems engineers to Celestion’s horn design capabilities. In the app, users can reliably verify designs, quickly adjust them with different parameters and view the results in a matter of seconds. Worthy successor of Arai Horns and TAD TH4001, it's a fully modern new conception for 1.4" and 1.5" compression driver, optimized at the mouth, the fins and the adaptor during FEA calculation. In this article, we’ll take a look at some of today’s most impressive high-end horn loudspeakers – the 15 examples featured are truly dreamlike.
How Does The Design Of A Horn Speaker Affect Its Sound Quality?
The honest frequency response starts from 20 Hz, the sensitivity is 105 dB, and the scale of the sound canvas that the Oswalds Mill Audio Imperia can draw can hardly be compared with anything. Old-fashioned speakers with impressive performance characteristics – Destination Audio Vista reach 105 dB of sensitivity, that is, even a one-watt amplifier can turn them on. Compression tweeter, midrange driver with a phenol diaphragm, a pair of 16” woofers and up to 120 dB of sound pressure – everything is fine here.
When discussing a vibrating diaphragm in a compression driver, this diaphragm has a radiation impedance. In the world of horn design, and from a user’s point of view, the most important function of a horn is to control sound directivity. This might seem very simple on the surface, however, horn design is complex. There is an infinite combination of horn profiles and lengths available and you can juggle horn design parameters all day long only to find that you still have to compromise.
Drawing upon my experiences, this piece will also offer insights into choosing the right horn for your speaker, ensuring the best sound output for your unique audio needs. In the audio and sound systems world, the term ‘horn’ holds significant importance. Despite its prevalence, many remain unaware of the crucial role that a loudspeaker horn plays in shaping and improving the sound we hear.
Loudspeakers weighing 500 kg each have a sensitivity of 114 dB, an impedance of 16 ohms and a frequency response of 20 – 33,000 Hz. The drivers used are 1” tweeter, 6” midrange, another lower midrange, 12” mid-bass (all in horns) and a 15” woofer with its own kW amplifier. Place the enclosure in a corner, and the room walls and floor serve as the final part of the flare, thus eliminating the need of making the box huge. The enclosure is not perfect, as the progression is roughly exponential and the length is short, so internal reflections can occur. Even so, efficiency of 40% is not unlikely with a folded horn speaker design. This is much more, compared to typical infinite baffle enclosure, which has around 0.5% efficiency.
Whether horn-loaded speakers sound better is subjective and heavily reliant on personal preference. The horn amplifies the sound and improves the directionality and control of the produced sound waves. Later, fiberglass layups became the material of choice for most manufacturers (but not all). Some HF horns were constructed from machined wood, a wonderful material actually, turned on a lathe. A heavily braced, rigid enclosure will produce a smoother, better looking curve than a poorly built cabinet (see the chart directly below).
Horn speakers offer a unique listening experience characterized by high efficiency, controlled directionality, and vibrant tonal qualities. The shape and size of the horn play a critical role in determining the sound’s directionality and frequency response. Adjusting these parameters allows the sound to be optimized for different listening environments. HornWizard is a mobile and desktop application, and a portal into Celestion’s powerful horn design software. It enables the user to test a basic concept design, using just a few parameters, to determine whether particular horn specification could work in practice.
The horn’s role is to manage the impedance between the speaker driver and the air, allowing for a more efficient transfer of energy. This results in higher sound output levels for the same amount of power input, making horns typically louder than regular tweeters. Four-way stalwarts, in which horns are used at medium and mid-bass frequencies. VIVA does not disclose all the characteristics of Nuda, assuring that it will be optimal to use speakers with proprietary tube amplification, and their frequency response of 20 – 30,000 Hz has a minimum error. Judging by the demonstrations at audio exhibitions, VIVA Nuda is really capable of driving even experienced audiophiles crazy. The amazing Viking Acoustic Grande Voix is not only a tribute to the past, but also a sound with excellent macro dynamics.
