The QSC AD-C820R SYSTEM is a high-output 8-inch coaxial in-ceiling loudspeaker package from the AcousticDesign Series, aimed at demanding installs such as large restaurants, houses of worship, atriums and cinema lobbies where high SPL and controlled coverage matter. The R designation indicates the round grille. Because it is packaged as a SYSTEM, it bundles the AD-C820 transducer/baffle assembly with the matching back-box enclosure and round grille for a complete ceiling-mount solution.
