The QSC AcousticDesign™ AD-P4T is a

4.5" two-way pendant-mount 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 ceiling, surface, and pendant applications, the AcousticDesign Series allows integrators seamless transitions within blended installations.

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 AD-P4T features a high quality 4.5" weather treated paper cone woofer with a 1" voice coil and a .075" aluminum dome tweeter positioned on a DMT waveguide.

The accurate frequency response of the AD-P4T is maintained even in 70/100V applications by use of a low-loss, lowsaturation 30-watt 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 enclosure is further protected by using UV inhibitors that prevent discoloration. 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 two quick-link cable assemblies and slip-lock fasteners to speed the installation. Located under a sealable input cover to prevent moisture at the terminals, a locking 4-pole Euro-block connector that can accept four 18AWG pairs eliminates the termination hassles of star topology wiring designs.

To further speed the install process while obtaining optimal results, Intrinsic Correction™ voicings are easily deployed via Q-SYS Platform and CXD Series amplifiers, as part of a complete QSC Systems solution.

The AD-P4T is available in QSC standard black (RAL 9011) or white (RAL 9010) and may be painted to match any decor.

For your system integration needs, complete EASE, CF2, CAD, and BIM files are available for download at QSC.com.
