[. . . ] AcousticDesignTM High-output Ceiling Mount Loudspeaker System Features · 12" low-frequency woofer · 1. 75" diaphragm compression driver · 300 watt continuous power rating · 70V/100V multi-tap transformer included (system can operate in distributed or low-impedance mode) AD-C1200 The AD-C1200 is designed for music playback, public address and distributed audio in applications that require high output from a ceiling mounted loudspeaker. [. . . ] In the optimized enclosure the usable low frequency of the system extends to 37 Hz. The 1. 75" compression driver fires through the center of the woofer and is acoustically mated to the woofer for a smooth transition at crossover. 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-C1200 loudspeaker system measures 93 dB sensitivity (1W/1m) and at full continuous power is capable of producing 118dB SPL (1W/1m) output.
