QSC AD-C820R SYSTEM

QSC AD-C820R SYSTEM 8-inch 2-way, 90° conical DMT™

The AD-C820 ceiling speaker is designed for music playback, public address and distributed audio in applications that require high output from a ceiling mounted loudspeaker. It uses custom designed transducers and crossover networks, in combination with an acoustically optimized enclosure (AD-C800BB). The 8″ woofer is equipped with a treated paper cone on a steel frame. In the optimized enclosure the usable low frequency of the system extends to 52 Hz. The 1.4″ compression driver fires through the center of the woofer and is acoustically mated to the woofer for a smooth transition at crossover. High-current, low tolerance network components provide smooth full-range, passive performance. The included 70/100 V, custom designed transformer is optimized for low line loss as well as accurate and transparent acoustic performance.
