QSC AD-C42T-WH 4-in 2-way Ceiling Speaker – White

The AcousticDesign Series of installation loudspeaker products from QSC Audio expands with the AD-C42T ceiling mount loudspeaker system. Designed for background and general purpose audio playback, the AD-C42T is compact and acoustically matched to the entire AD Series. Rated for 40 watts continuous power handling and able to take up to 160 watt peaks, the compact AD-C42T is suitable for a wide variety of ceiling installations.

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 100 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 for compliance with European safety standards.

The AD-C42T is factory shipped with C-rings and tile rails for installation. New construction rings (AD-NC4) and mud rings (AD-MR4) are also available separately. The AD-C42T is equipped with a 70/100 V transformer with multiple taps and an 8 ohm bypass.
