Patented Omnidirectional Sound Technology by Francesco Pellisari

Technology

The Acoustic Image

An acoustic image is produced when the brain senses an acoustic wave and other environmental information. The human brain calculates where all the sound is coming from and draws its own three-dimensional image to identify the sound, its direction and volume.

Speakers designed by Francesco are the result of comprehensive study not only of the measurements of acoustic waves but also the awareness of psychoacoustics, or rather how the sound is interpreted by the human brain.

Designing a speaker, in fact, is not only about fiddling with mathematical calculations. It has more to do with undertaking a project in which the end-result is defined in terms of both science and the physiology of listening, physics and psychoacoustics. Rather than using just cold calculations, we use the harmony of sound as the basis for achieving our all-important goal: the listening experience.



Omnidirectional versus traditional directional sound technology

Omnidirectional Sound Technology

The patented omni-directional technology allows the speakers to radiate sound spherically, creating a stable sound, emitted equally in all directions. With none of the usual positioning restrictions, the mechanical resonance is reduced — producing a rich, natural and consistent sound almost everywhere on the site of installation. For example, in a church, by suspending the speakers from the ceiling, it is possible to tune them and resolve architectonic-related sound problems.

Production in Italy

The hand-crafted ceramic speakers are shaped and glazed by highly-skilled artisans and engineers in Italy. Ceramic has excellent acoustic properties, producing an astoundingly natural and pure sound.

The specific ceramics used by Francesco are tailored for producing the finest sound quality and also for their high rigidity.

In some of our sound art projects, "glazed ceramic" produced by the world-famous Ceramica Gatti 1928 have been used to provide the required artistic finish.
