The QSC AD-C821R SYSTEM is a fully integrated 8-inch coaxial in-ceiling loudspeaker from the AcousticDesign Series with a round grille. Unlike the AD-C820, the AD-C821 is a factory-sealed, blind-mount system that installs directly into a ceiling tile or drywall without a separate back-box assembly, speeding installation in retail, hospitality and worship spaces that still demand high output. The R designation indicates the round grille, and the SYSTEM package includes the integrated loudspeaker, matching grille, tile rails and c-ring.
