The AD-S4T features a high quality 100 mm
[4 in] weather treated paper cone woofer
on a 25 mm [1 in] voice coil. A carefully
selected 19 mm [.75 in] silk dome tweeter
with a 19 mm [.75 in] voice coil perfectly
matches the sensitivity and performance
of the woofer for outstanding full-range
reproduction.

with a 19 mm [.75 in] voice coil perfectly

of the woofer for outstanding full-range

Consistent and even 120° 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-S4T is maintained even in
70/100V applications by use of a low-loss,
low-saturation 30-watt transformer with
ZLSLJ[HISL[HWZPUJS\KPUNHU£I`WHZZ
To preserve weather resistance, the rotary
selector is located on the back of the
enclosure, protected by a weather grommet.

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 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.
