Multiactuator panels have been used as an alternative to classical loudspeakers in wave field synthesis because of their added benefits: low-visual profile and diffuse radiation. Panels consist of a thin, stiff panel with a small back volume, which vibrates by a group of mechanical exciters. Because of their diffuse pattern and omnidirectionality, individual components of the sound pressure field merge correctly to form a larger sweet spot in the reproduction space. A comprehensive review of prototype panels in many research projects reveals the relevant issues, such as spatial aliasing, room acoustics, and finite boundaries.
