QSC AD-C821R SYSTEM High-Output Ceiling Speaker

The AD-C821R SYSTEM is a fully integrated, factory-sealed version of QSC's high-output AcousticDesign ceiling speaker, acoustically identical to the AD-C820 but built as one sealed unit with a dog-ear mounting scheme instead of a separate baffle and back box. The package adds a set of tile rails, a c-ring, and a round grille, so a blind-mount install needs nothing extra.

The same 8 inch treated-paper woofer and 1.4 inch compression driver deliver 90 degree axisymmetric coverage, and the factory-mounted 70V/100V transformer is a custom low-distortion, laminated-core design. Because the enclosure ships sealed at the factory, the C821 install is faster where a separated back box isn't needed.
