The ORUS is an omni-directional, non-coherence, sound wave speaker which was patented in 1996. This artistic sound sculpture was produced and installed by Francesco Pellisari and NacSound www.francescopellisari.com.
Vitra Museum, Berlin
The oval geometric shape has very high resonance modes and the reflective walls had inadequate acoustics for a conference room. The use of a single hyperdirectional central speaker and sound-absorbing armchairs solved the problem. The stereo effect was created via two direct speakers filtered in low and medium frequencies.
Radisson Hotel, Rome
This hotel in the centre of Rome was a special project to increase the quality of the acoustics within the area. Because the walls were made from reflective materials, metal and glass, the project was difficult to solve. The solution was a stunning Freewheeler speaker, an aluminum omni-directional speaker and several ZEMI and OMNI. Architects: King Roselli
