The QSC AD-C821S SYSTEM is the square-grille variant of the AcousticDesign AD-C821, a fully integrated 8-inch coaxial in-ceiling loudspeaker. As a factory-sealed, blind-mount system it installs directly into a ceiling tile or drywall without a separate back box, making it a fast, high-output choice for retail, hospitality and worship spaces. The S designation indicates the square grille for a cleaner architectural appearance. The SYSTEM package includes the integrated loudspeaker, matching square grille, tile rails and c-ring.
