Avalon Acoustics Tesseract Floorstanding Loudspeakers

The Avalon Acoustics TESSERACT represents the culmination of over 25 years of research into the subtleties of musical waveforms and the psychoacoustic perception of sounds in space. Avalon’s research into physical forms and how they react with ambient musical information has led us to two essential innovative concepts. First, it is possible to make a large full range system fully disappear sonically. Second, it is possible to create 3-dimensional images within a soundstage using conventional stereo recordings.

Avalon’s Stealth Technology, the redirecting and diffusion of ambient room energy, makes the disappearing act possible. The use of tensor field mathematics, assigning a value and direction to expanding harmonic waves, along with enormous amounts of number crunching, has given Avalion the ability to make reliable predictions regarding which physical forms will best disappear in space. Making an array which is over 7 feet tall disappear is quite a feat of practical mathematical prediction and actual form fabrication.
