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.
