Product Overview
The QSC AD-C1200 is a 12-inch coaxial ceiling-mount loudspeaker for music playback, public address, and distributed audio in spaces that demand high output from an in-ceiling source. It is designed for larger commercial venues that need long-throw coverage from the ceiling plane.
Product Description

The QSC AD-C1200 ceiling loudspeaker combines a 12-inch low-frequency woofer with a 1.75-inch diaphragm compression driver in a coaxial arrangement, with the transformer and crossover network factory-mounted on a steel baffle. It is rated for 300 watts continuous power handling with 600-watt peaks, and the included 70/100V multi-tap transformer allows distributed or low-impedance operation. The baffle mounts to the QSC AD-C1200BB enclosure or any roughly 2.5-cubic-foot enclosure using industry-standard transducer dimensions. Add the matching QSC AD-C1200BB enclosure and the AD-C1200SG square grille to complete the installation.
