The QSC AcousticDesign™ AD-S6T is a
surface mounted 70/100V, 6.5" two-way
loudspeaker system, ideally suited for a
wide variety of foreground and background
sound reinforcement applications.
AcousticDesign™ series offers integrators a
premium quality installed sound solution
where performance, coverage, and
aesthetics are paramount. Combined with
unprecedented ease-of-installation and high
weather resistance, the AcousticDesign™
Series provides integrators a versitile and
confident response.
The AD-S6T features a high quality 6.5"
weather treated paper cone woofer on a
1.5” voice coil. A carefully selected 1” silk
dome tweeter with a 1” voice coil perfectly
matches the sensitivity and performance of
the woofer for outstanding full range
reproduction.
Consistent and even 105° axisymmetric
(conical) coverage is realized by means
of DMT™ (Directivity Matched Transition).
This innovation matches the high frequency
wavegide to the woofer coverage at the
crossover point, resulting in a coherent
transducer transition and improved off
axis response.
To maintain this frequency response, the
AD-S6T utilizes a variable tap 60 watt low
saturation and low loss 70/100V
transformer with 8Ω bypass, accessible via
a rotary selector located on the enclosure
back under a weather grommet for
improved weather resistance.
All AcousticDesign™ Series surface-mount
loudspeakers are housed in rugged ABS
enclosures for long-term durability. Sealed
input panel covers and powder coated
aluminum grilles add weather resistance,
exceeding IEC60529 IP-54 for dust and
splash resistance.
Installers will appreciate the award winning
X-Mount™ system, included with each full
range AcousticDesign™ model. This
ingenious mounting solution achieves
unprecedented ease-of-installation in either
horizontal, vertical, wall, or ceiling
deployments. Knurled surfaces at the pivot
planes ensure the load will not drift or sag
over time. Articulation marks allow
preconfiguration of the X-Mount™ while on
the ground with no special tools required.
Once secure, the loudspeaker installs in
seconds, allowing the installer to work safer,
smarter, and faster with repeatable results.
To further enhance performance and speed
of install with optimum result, advanced
voicing filter sets using QSC Intrinsic
Correction™ techniques are obtainable
using the Q-SYS Platform including CXD
Series amplifiers for a complete QSC
systems solution.
Sensitive to aesthetic demand, the
AcousticDesign™ Series feature a stylish
appearance free of obtrusive logo
adornments. Complimenting adjacent
product families, AcousticDesign™ surface
loudspeakers are available in QSC standard
black (RAL 9011) or white (RAL 9010) and
may be painted to match any decor.
To assist in successful systems integration,
complete EASE, CAD, and BIM files are
available for online download at QSC.com.
