QSC AD-C1200 AcousticDesign Ceiling Mount Speaker

Get trouble-free operation in various applications with the AD-C1200 ceiling speaker from QSC. Ideal for music playback, public address, & distributed audio.

Designed for music playback, public address, and distributed audio in applications that demand high output from a ceiling-mounted loudspeaker, the QSC AD-C1200 ceiling-mount speaker offers trouble-free operation and versatility. Part of the AcousticDesign™ Series of installation loudspeakers, the AD-C1200 uses custom-designed transducers, crossover networks, and an acoustically optimized enclosure, all working together to offer a versatile and reliable high-ceiling solution.

Included with the AD-C1200 are coaxial transducers, a transformer, and a crossover network factory mounted on a steel baffle. The baffle can be mounted to the QSC enclosure or any ~2.5 ft3 enclosure using industry-standard transducer mounting dimensions. To finish the installation, a square grille (AD-C1200SG) is available).

Optimal sound quality is ensured in the construction of the AD-C1200. A treated paper cone on a steel frame is used to make the 12” woofer. Within the optimized enclosure the usable low frequency for the system extends down to an impressive 37 Hz. A smooth transition at crossover is provided since the 1.75” compression driver fires through the center of the woofer and is acoustically mated to the woofer. Overall, the system offers axisymmetric coverage of 85 degrees.

Enjoy smooth, full-range, passive performance with the high-current, low-tolerance network components within the AD-C1200. The 70V/100V custom-designed transformer is optimized to deliver accurate and transparent acoustic performance along with low line loss.

Get impressive SPL and sensitivity for a ceiling system: the AD-C1200 measures 93dB sensitivity and can produce 118dB SPL at full continuous power.
