The QSC AD-S.SUB is part of the
AcousticDesign™ Series SUB/SAT
loudspeaker line which are ideally suited for
background music applications that require
refined depth and clarity even at lower volume
settings.
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-S.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 accurate frequency response of the
AD-S.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 in mono mode.
The AD-S.SUB includes built-in high-pass
filtered outputs for connecting up to four
AcousticDesign Series satellite loudspeakers.
This feature greatly reduces system setup,
amplifier channel count, and allows for ease
of wiring.
The inputs and outputs are located behind
a reversible rear panel. The input panel
features convenient cable tie anchor points
to dress the installation. All in-thru and
outputs are terminated to locking 4-pole
Euroblock style connectors capable of
12AWG (2 mm) wire thickness.
Configuring the AD-S.SUB for operation is
made simple by clearly defined rotary
selectors and isolated inputs allowing for
faster and more reliable setup.
The two-piece mounting system is a slip
locking V design with minimal wall
protrusion and has a set screw to lock in
place. The wall mounting hardware is also
reversible allowing the port tubes to be
oriented in the desired direction.
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 the
Q-SYS Platforms, including CXD-Q Series
amplifiers, as part of a complete QSC
systems solution.
The AD-S.SUB is available in QSC standard
black (RAL 9011) or white (RAL 9010).
For your system integration needs,
complete EASE, CF2, CAD, and BIM files
will be available for download at QSC.com.

2) Reference plane is the plane coincident with the loudspeaker baffle plane. Reference axis is the axis perpendicular
to the reference plane and passing through the center of the baffle. Vertical plane is the plane intersecting the
reference plane at a right angle, including the reference axis and the taps selector knob. Horizontal plane is the plane
intersecting the reference plane and the vertical plane at a right angle, including the reference axis.
