History
Hoorns zijn de oudst bekende vorm van geluidsversterking bekend bij de mens. Al toen de eerste mens een tunnel maakte met zijn handen om het geluid te versterken, was het principe van versterking door acoustische transformatie een feit.

De meeste blaas instrumenten gebruiken een hoorn om hun geluids weergave te vergroten.

Het principe werd ook al gebruikt in vroegere Bioscoop speaker systemen, welke de mensen de kriebels op hun rug bezorgden. Ze moesten een grote ruimte met geluid vullen, met gebruik van alleen vrij zwakke buizenversterker. Dus heb je goed efficiente luidsprekers  dan heb je niet meer nodig dan een eenvoudige neutrale versterker, om een verbazingwekkende weergave te realizeren.

The theory
Bass frequencies, which normally would be transformed into heat inside a speaker case, are channeled through a funnel of precisely defined hyperbolic contours, undergoing an acoustic transformation which eventually delivers impressive natural amplification - the visible opening of the horn acts like a membrane of the same size, yet, not having a mass, without all the disadvantages of moving masses.

The efficiency of conventional speakers lies somewhere around 2 percent, i.e. 98 percent of the supplied energy is transformed into heat. Typical efficiency ratings of horns vary between 10 and 12 percent. This enormous advantage allows you to use low output tube amplifiers, delivering subtle dynamics and smooth frequency response even at very low volumes. But of course, you're not limited to these levels; playback at actual concert volume is not a problem either.

Full-range drivers
Using only one full-range driver in a speaker gets as close as possible to an ideal point-like sound source. It emits the entire audible frequency spectrum, and unlike speakers with several drivers, doesn't need shunts and can be connected directly to the amp.

For multi-way speaker systems, however, the input signal must be split in the different frequency ranges, which requires significant technical efforts, bringing about a number of severe problems:

You get phase displacements. A single sonic event, that should reach the ear at a distinct point of time, is broken up into a number of discrete events, thus impairing the precision of sound reproduction.

Directional hearing requires a certain interaural time variance. If this variance is ambiguous, however, depth information and plasticity get lost. Formants are frequency ranges containing particularly strong harmonics. They have great influence on the timbre of a sound. When formants are distributed over more than one driver, the characteristic spectra of instruments and human voices are impaired.

Psychoacoustics teaches us about the recognition of instruments depending greatly from its temporal flow, especially attack and decay. If the reproduction of these events is not correct, characteristic features of instruments are mangled. The consequence: the sound seems sterile.

Full-range drivers eliminate all of these problems. The resulting homogeneity and plasticity are superior to everything you could expect from multi-way speakers. The character of the performance remains unadulterated. The music sounds deceptively real. The atmosphere of the room where the music was recorded, be it a great concert hall or an intimate jazz club, is reproduced amazingly well. You'll feel like actually being there, not like listening to a sound conserve.
