The QSC AD-C.SUB is part of the

AcousticDesign ™ volume settings.

Series SUB/SAT loudspeaker line which are ideally suited for background music applications that require refined depth and clarity even at lower

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 enclosures, the AcousticDesign Series allows integrators seamless transitions within blended installations.

The AcousticDesign Series SUB/SAT loudspeakers have been specifically designed to be mix-and-match capable.

Any combination of satellites may be paired with any subwoofer in the SUB/SAT line.

The AD-C.SUB features a high quality

6.5-inch weather treated paper cone woofer on a dual voice coil for improved thermal dissipation and higher output within a small form factor.

The inputs and outputs are located behind a removable conduit cover plate with captive screws to prevent loss during installation. All in-thru and outputs are terminated to locking 4-pole Euroblock style connectors capable of 12AWG (2 mm) wire thickness.

To retain their stylish aesthetics, 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 4x double stepped, long travel dog-ear blind mounting system, which captures from 0 - 2 in of ceiling thickness.

Intrinsic Correction ™ voicings that optimize performance and speed the install process are easily deployed via the MP-M Series music and paging mixers as well as Q-SYS

Platform, including CXD-Q Series amplifiers, as part of a complete QSC systems solution.

The accurate frequency response of the

AD-C.SUB is maintained even in 70 / 100 V applications by use of a low-loss, lowsaturation 100 W transformer with selectable taps, including 4 Ω bypass, using a rotary selector located under the snap-fit magnetically attached powder coat steel grille.

The AD-C.SUB includes built-in high-pass filtered outputs for connecting up to four

AcousticDesign SUB/SAT satellite loudspeakers. This feature greatly reduces system setup, amplifier channel count, and allows for ease of wiring.

The AD-C.SUB 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.
