QSC Expands AcousticDesign Family

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

The AD-C1200 High-output Ceiling Mount Loudspeaker System features 12-inch low frequency woofer, 1.75-inch diaphragm compression driver, 300W continuous power rating, and a 70V / 100V 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.

Each AD-C1200 includes the coaxial transducers, a transformer and a crossover network, factory mounted on a steel baffle. 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 37Hz, according to the company. 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 degrees of axisymmetric coverage.

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

The AD-C820/C821 features an 8-inch low-frequency woofer, 1.75-inch diaphragm compression driver, 200W continuous power rating, 70V / 100V multi-tap transformer (enabling the system to operate in distributed or low-impedance mode) and AD-C820 transducer/baffle assembly for separated backcan installation. The AD-C821 has been designed as a fully integrated blind-mount system.

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, says QSC. 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).

The 8-inch 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 52Hz. The 1.75-inch compression driver fires through the centre of the woofer and is acoustically mated to the woofer for a smooth transition at crossover. The system achieves 105 degrees of axisymmetric coverage.

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