QSC AcousticDesign AD-C42T 4" 2-Way Ceiling Speaker, Weather Resistant, 72Hz-20kHz at -6 dB Frequency Response, 70/100V Transformer, Pair, White

The QSC AcousticDesign AD-C42T 4" 2-Way White Ceiling Speaker (Pair) is rated for 40 Watts continuous power handling and able to take up to 160 Watt peaks. The 4 " woofer is equipped with a polypropylene cone for protection in humid environments. The driver features a synthetic rubber surround and in its sealed enclosure is optimized to deliver useable low frequency extension below 70 Hz. The high frequency device is a co-axial, post mounted 0.75 " dome tweeter with a titanium diaphragm and a cloth surround. The coaxial post is mounted slightly off center in relation to the low frequency driver in order to lessen the destructive interference often found with axisymmetric post mounted coaxial systems.

The conical dispersion of the AD-C42T is 100deg. and sensitivity measures 88 dB SPL. The baffle and mounting tabs are molded from high- impact polystyrene. The rear enclosure is a heavy gauge, powder coated steel. The attractive aluminum grille is backed with an acoustically transparent white cloth. On the rear of the enclosure is an input cup that features a conduit attachment point plus an additional knockout for daisy-chain wiring. Input signal connection is made with a high temperature resistant ceramic screw terminal. The AD-C42T is equipped with a 70/100 V transformer with multiple taps and an 8 Ohms bypass.
