Ceiling range expands with two new high-output models
QSC Audio has announced an extension to its Acoustic Design ceiling speaker range, with the release of two new high-output models – the AD-C1200 and AD-C820/C821 – at the ISE show in Amsterdam.
The AD-C1200 features a 12-inch low frequency woofer, 1.75-inch diaphragm compression driver, 300W continuous power rating, and a 70/100V multi-tap transformer (enabling the system to operate in distributed or low-impedance mode).
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 cubic-feet 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 optimised enclosure the usable low frequency of the system extends to 37Hz. 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 85-degree axisymmetric coverage.
High-current, low tolerance network components provide smooth full-range, passive performance. The included 70V / 100V custom designed transformer is optimised for low line loss as well as accurate and transparent acoustic performance.
The AD-C1200 loudspeaker system measures 93dB sensitivity (1W/1m) and at full continuous power is capable of producing 117dB SPL (1W/1m) output.
This model is complemented by the AD-C820/C821, which features an eight-inch low frequency woofer, 1.750-inch diaphragm compression driver, 200W continuous power rating, 70/100V multi-tap transformer and AD-C820 transducer/baffle assembly for separated backcan installation. The AD-C821 has been designed as a fully integrated blind-mount system.
The usable low frequency of the system extends to 52Hz and achieves 105-degree axisymmetric coverage. It measures 91dB sensitivity (1W/1m) and at full continuous power is capable of producing 114 dB SPL (1W/1m) output.
