Holophones loudspeaker system was designed in 1999 by composer Michelangelo Lupone and realized at CRM – Centro Ricerche Musicali in Rome, in order to realize a specific sound spatialization defined as "wavefront sculpture".[1] The parabolic reflector of the Holophones system emits plane waves.[2][3] Each unit of the Holophones system consists of a parabolic dish with a limited band loudspeaker at its focal point, with controllable radiation angle. The dynamic controls for sculpturing the wavefront are managed by a computer.[4]
