Alsyvox was created by Daniele Coen, an Italian aerospace engineer, and Paola, an Italian interior designer. The engineering is Italian; the speakers are built in Valencia, Spain.
They make loudspeakers the difficult way: no cone woofer, no dome tweeter, no horn-loaded midrange, and no box — neither sealed nor ported. Every panel is a full-range ribbon and ribbon-planar dipole, radiating from both sides as a line source.
The diaphragm moves like a layer of air as the sound wave crosses it. That is where the transparency comes from: the music stops sounding like it is coming from the speakers and starts filling the room.
