Sound Advance A Truly Invisible, Extended-Bandwidth, Wide-Dispersion Loudspeaker System The extraordinary SOUND ADVANCE SA2C is a two-way, full-range planar loudspeaker system designed for application in commercial and residential installations. Its proprietary structural and engineering features make it possible to invisibly install in almost any standard wood/metal stud wall or ceiling, essentially becoming an integral part of the wall or ceiling surface. Because of the SA2C's patented Planar Diaphragm Technology™, when properly installed in a wall or ceiling, the loudspeaker system will radiate in a smooth, even coverage hemispherical pattern with more than 140° of dispersion throughout its bandwidth.
