The QSC AcousticDesign™ AD-S10T is a 
surface mounted 70/100V, 10” 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 versatile and 
confident install solution.
The AD-S10T features a high quality 10” 
weather treated paper cone woofer on a 2.5” 
voice coil. A carefully selected 1” exit, 1.4” 
compression driver perfectly matches the 
sensitivity and performance of the woofer 
for outstanding full-range reproduction.
Consistent and even 90° axisymmetric 
(conical) coverage is achieved through 
DMT™ (Directivity Matched Transition), a 
QSC innovation which matches the 
directivity patterns of the woofer and the 
high-frequency waveguide at the crossover 
point. The result is a coherent transition 
between transducers and improved off-axis 
response.
The even, accurate frequency response of 
the AD-S10T is aided by a 100-watt low-loss, 
low-saturation transformer with selectable 
taps, including an 8Ω bypass. To enhance 
weather resistance, the rotary selector is 
located on the back of the enclosure, 
protected by a weather grommet.
With rugged ABS enclosures, sealed input 
panel covers, and powder-coated aluminum 
grilles for weather resistance, the 
AcousticDesign™ surface mounted series 
exceed IEC60529 IP-54 ratings for dust and 
splash resistance.
Installers will appreciate the award-winning 
X-Mount™ system included with each fullrange AcousticDesign™ model. This 
ingenious mounting solution achieves 
unprecedented ease-of-installation in 
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.
The AD-S10T also includes M10 fittings for 
optional yoke mount (YMS10T) or shoulder 
eybolt (M10 Kit-C) accessories for installation 
versatility.
To further enhance performance and speed 
of install with optimum result, advanced 
voicing filter sets using QSC Intrinsic 
Correction™ techniques are obtainable using 
Q-Sys networked audio processing 
platforms, including CXD amplifiers for a 
complete QSC systems solution.
The AcousticDesign™ series feature a stylish 
appearance free of obtrusive logo 
adornments for aesthetically sensitive 
installations. 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.
