The AcousticDesign™ Series of installation loudspeakers has been designed for trouble free operation and versatility. They use custom designed transducers and crossover networks, in combination with an acoustically optimized enclosure (AD-C800BB). These loudspeakers continue the AD Series philosophy of bringing natural and accurate sound quality combined with versatility and reliability to high-ceiling applications.

FEATURES

• 8" low-frequency woofer
• 1.4" diaphragm compression driver
• 200 watt continuous power rating
• 70V/100V multi-tap transformer included (system can operate in distributed or low-impedance mode)
• AD-C820 transducer/baffle assembly for separated backcan installation

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 are capable of producing 114 dB SPL (1W/1m) output.
