We are proud to introduce the first speaker to recreate sound from the original recording the same way nature produces sound in the recording environment. We leverage the same laws of physics that nature uses so our speakers will capture your attention and release the same physical and emotional impact of a live performance.

Ours is the first speaker system harnessing the Fourier Theorem* and Iso-Dynamic Driver Displacement*, which allows the dynamics and detail once only achieved with the world’s best headphones. Yet even better, without having to turn your speakers up to concert level volumes. We recreate in your listening room what only the best headphones can do: recreate full range phase coherence where is matters.

By reducing the functional inertia of our large drivers by 100,000 to over 250,000 times, our patented algorithm strips away mechanical sluggishness. We are leveraging the natural mathematical organization of acoustic instruments and the biological limits of human hearing to make a zero-hysteresis drive possible. The result is massive air displacement delivered with zero perceivable lag—achieving true acoustic realism thus making it possible to experience the physical impact and musical satisfaction of being at the recording studio or concert venue.

Your family and neighbors appreciation of our speaker system will be second only to your own, while you luxuriate in realism and naturalness unmatched in the industry, while being far less likely to disturb them.

Extraordinary claims require extortionary evidence so listen to our speakers, a brand-new single unit model, at our next show (Axpona 2027) or visit us in our soon to be completed show room in Seattle, Wa. In the meantime, review a little of our history and goals in the video below.

U.S. Patent No. 12,395,783

“… the Fourier sounded great—open like an omni (which is what it is) with free-floating images of extremely natural timbre …

“… the Fourier Transforms were best-of-show realistic-sounding in the mids and treble.”

The Absolute Sound - Axpona 2025: Loudspeakers

  • The scaling of the driver(s) physical surface area to the exact volumetric demands of the frequency, eliminating mechanical compression and resulting in true acoustic realism.

  • According to the Fourier theorem, a complex wave is composed of a series of sinusoidal components whose frequencies are those of the fundamental and its harmonics, each component having the proper amplitude and phase. The sequence of components that form this complex wave is called its spectrum.

“Using the Fourier theorem as a guiding light, these loudspeakers should, in their completed form, rival even the finest electrostatic or planar headphones in terms of accuracy and speed.”
