QSC Audio has announced an extension to the AcousticDesign ceiling loudspeaker range with the release of two new high-output models: the AD-C1200 and AD-C820/C821.

The AD-C1200 features 12-inch low frequency woofer, 1.75-inch diaphragm compression driver, 300-watt continuous power rating, and a 70-volt/100-volt multi-tap transformer (enabling the system to operate in distributed or low-impedance mode).

The AD-C1200 has been designed for music playback, public address and distributed audio in applications that require high output from a ceiling mounted loudspeaker.

Utilizing custom designed transducers and crossover networks, in combination with an acoustically optimized enclosure (AD-C1200BB), the AD-C1200 embraces the AD Series philosophy by bringing versatility and reliability to high-ceiling applications.

Each AD-C1200 includes the coaxial transducers, a transformer and a crossover network, factory mounted on a steel baffle. The baffle is designed to mount to the QSC enclosure or to any ~2.5 ft3 enclosure using industry standard transducer mounting dimensions. A square grille (AD-C1200SG) is available to complete the installation.

The 12-inch woofer is made with a treated paper cone on a steel frame. In the optimized enclosure the usable low frequency of the system extends to 37 Hz. 

The 1.75-inch compression driver fires through the center of the woofer and is acoustically mated to the woofer for a smooth transition at crossover.  The system achieves 85-degree axisymmetric coverage.

High-current, low tolerance network components provide smooth full-range, passive performance. The included 70-volt/100-volt custom designed transformer is optimized for low line loss as well as accurate and transparent acoustic performance.

The AD-C1200 loudspeaker system measures 93 dB sensitivity (1W/1m) and at full continuous power is capable of producing 117 dB SPL (1W/1m) output.
