Horn loudspeaker system is the oldest design in sound reproduction. Even till today, it is the least known design in the sound industry. Most of us audiophiles don’t really know what goes on behind that protruding horn that emits sound so effortlessly. It started more than a hundred years ago, when Emil Berliner presented his gramophone to the public for the first time. The horn of the gramophone amplified the mechanical oscillations of a pin running along a groove in a disc producing a sound that could be heard by the human ear. Common knowledge tells us that horns are transforming pressure by using a sound source, which means a driver. Thus they work in principle the opposite to a human ear. The ear consists of the outer, the middle, and the inner ear. The outer ear gradually decreases in diameter via the auditory canal towards the eardrum. The pressure increases accordingly. Thus, by means of this design, we can perceive infinite pressure variations, which enables us to hear far better. Horn loudspeakers, however, are supposed to work the other way around. For this purpose, a sound emitting membrane is placed at the beginning of the horn, which means the horn throat. Compared with the human ear, the horn is used from the other side. The operational membrane has to oppose an increased pressure induced by the horn shape. Dynamic pressure amplitudes are reproduced extremely fast and the membrane very quickly reaches back its neutral position. Due to this fact, the quick suppression of post oscillations in horn loudspeakers results in an exceptionally audible resolution of infinite details. Music consists of constantly changing intensities, which means sound levels can vary in their intensity depending on the music. A loudspeaker has to follow these impulses accordingly, and should reproduce them as precisely as possible. Due to the significantly reduced membrane excursion a horn loudspeaker is extremely quick. This does not refer to its acceleration behavior, but this as well applies to its deceleration capacity, since the acoustical attenuation through the horn causes considerably reduced amplitude of post oscillations. Moreover the reduced membrane excursion and the acoustical attenuation through the horn avoid critical partial oscillations of the membrane. Thus, distortions are nearly nonexistent and dynamic compression does not occur. Horn loudspeakers are the most natural physical concept for the sound reproduction. Even today its characteristics offer indisputable advantages compared to other loudspeaker systems. Horn loudspeakers concept has the ability to transfer low electrical power into high sound levels. Horn loudspeaker pioneers designers as Gustavas, Webster, Klipsch and Voigt required decades in order to explore the laws of the horn technology. Paul Voigt submitted his first tractrix horn to the British Patent Office in 1926. Famous classics horn loudspeakers designs were “The Voice Of The Theatre” designed by Altec Lansing, the Klipschorn by Paul Klipsch, the Imperial Hyphex Horns by Jensen Manufacturing Company, the Voigt Domestic Corner Horn by Paul Voigt of Voigt Patents Ltd and Acousta and Audio-vector by Lowther. 
Avantgarde Acoustic Horn loudspeakers stands for a vision. It is the vision to bring the horn technology to its limits and create in over 10 years of development a timeless and elegant product portfolio.The symbiosis of classic and modern, of form and function, fascination and Zeitgeist. A homage to the first pioneers of the hornspeaker technology. Paul Klipsch and Paul Voigt. You can find out more about this amazing loudspeaker at Audio Note Singapore Pte Ltd.
