Details

The AD-C820 and AD-C821 are acoustically identical and designed for music playback public address and distributed audio in applications that require high output from a ceiling mounted loudspeaker. The AcousticDesign™ Series of installation loudspeakers has been designed for trouble free operation and versatility. Both models use custom designed transducers and crossover networks in combination with an acoustically optimized enclosure (AD-C800BB) or as a fully integrated sealed system (AD-C821). These loudspeakers continue the AD Series philosophy of bringing natural and accurate sound quality combined with versatility and reliability to high-ceiling applications.

Each AD-C820 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 (AD-C800BB).

The AD-C821 is a fully integrated factory sealed system using a "dog-ear" style mounting scheme. To better blend with the facility architecture either speaker may be installed with your choice of a round (AD-C800RG) or square (AD-C800SG) grille (offered separately).

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. The system achieves 90 degree axisymmetric coverage.

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

The AD-C820/C821 loudspeakers measure 91dB sensitivity (1W/1m) and at full continuous power is capable of producing 114 dB SPL (1W/1m) output.
