The AD-C1200 High-output Ceiling Mount Loudspeaker System features 12" low frequency woofer, 1.75" 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.
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. Both models use custom designed transducers and crossover networks, in combination with an acoustically optimised enclosure (AD-C800BB), or as a fully integrated, sealed system (AD-C821).
