The QSC AcousticDesign™ AD-C4T is a 4.5" two-way ceiling loudspeaker ideally suited for a wide variety of foreground and background sound reinforcement applications which utilize 70/100V or 16Ω bypass configurations.
The AcousticDesign™ series offers integrators a premium quality installed sound solution where performance, consistent coverage, and aesthetics are paramount. Specifically designed to maintain a consistent tonal characteristic across the entire family in both ceiling or surface applications, the AcousticDesign series allows integrators seamless transitions within blended installations.
The AD-C4T features a high quality 4.5" weather treated paper cone woofer with a 1" voice coil and a 1" aluminum dome tweeter which is positioned on a DMT waveguide in front of the woofer. DMT (Directivity Matched Transition™), is QSC’s design philosophy where the high frequency waveguide is matched to the natural conical behavior of the woofer at the crossover point. The result is a coherent transition between transducers with improved off-axis power response for consistent 150° conical DMT coverage.
The accurate frequency response of the AD-C4T is maintained even in 70/100V applications by use of a low-loss, low saturation 30W transformer with selectable taps, including 16Ω bypass, using a rotary selector located under the snap-fit magnetically attached powder coat steel grille.
To retain lasting good looks, the rugged ABS baffle is further protected by using UV inhibitors that prevent discoloration and by a powder coated steel back can. The magnetic grille features a stick-on logo that can be removed blemish-free for installations where branding is not permitted.
Installers will appreciate the 3x double stepped, long travel dog-ear blind mounting system, which captures from 0" - 2.25" of ceiling thickness. A captured Phillips screw provides access to the removable conduit cover plate; also available as an accessory, as is a separate mud-ring for pre-install wiring. A locking 4-pole Euro-block connector that can accept four 18AWG pairs eliminates the termination hassles of star topology wiring designs.
Intrinsic Correction™ voicings that optimize performance and speed the install process are easily deployed via Q-SYS networked audio processing platforms, including CXD power amplifiers, as part of a complete QSC systems solution.
The AD-C4T is available in QSC standard black (RAL 9011) or white (RAL 9010) and may be painted to match any decor.
The QSC AD-C4T is a replacement for the Discontinued QSC AD-C42T, AD-Ci52T and AD-Ci52ST.
