TESSERACT Signature represents the culmination of over 30 years of research into the subtleties of musical waveforms and the psychoacoustic perception of sounds in space. Our 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.

Our 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 us the ability to make reliable predictions regarding which physical forms will best disappear in space. Making an array that is over 7 feet tall disappear is quite a feat of practical mathematical prediction and actual form fabrication.

Sonic Holography is accomplished through meticulousness in recovery and preservation of low-level signal information which is encoded into any well-made recording. Whenever a microphone is open it is collecting phase and spatial information which is rarely fully decoded by a playback system. This fragile information may be destroyed at many stages of the recording/playback process. Our goal is to preserve as much of the truth that inhabits each recording without putting our own fingerprints on the final presentation.

Most importantly, we never apply a technique without considering the effect it will have on the emotional content of the presentation. For us, technique is always in service to the music. There must be an aesthetic or emotional result for each intellectual or technical choice we make, one that speaks to our souls.
