AD-S52
AcousticDesign™ Loudspeaker
The QSC AcousticDesign AD-S52 is a full range,
surface mount loudspeaker with sleek, contemporary
styling that fits perfectly into multiple environments
and applications including hotels, restaurants,
convention facilities, and multimedia environments.
The loudspeaker’s low-frequency driver is magnetically
shielded, making the AD-S52 perfect for use near
video monitors. Available in black or white, these great
sounding, weather resistant enclosures can be painted
to match any specific decor.
The AD-S52 is a high output, 2-way design
incorporating a 5.25" weatherproof, LF transducer and
a 1 " neodymium tweeter. This exceptional loudspeaker
carries the added benefit of built-in dynamic power
protection—thus ensuring system reliability in the
event of overload conditions.
The AD-S52T models are equipped with a 70/100 volt
matching transformer for distributed audio systems.
There is a transformer tap switch on the rear panel
for setting the power level of the loudspeaker. This
switch may also be set for 8 ohm operation, bypassing
the transformer completely—providing greater system
flexibility compared to most competing products.
The AD-S52 system package includes a ball mount
assembly for convenient installation of the enclosure
in a wide variety of orientations. If desired, the ball
mount adapter’s back plate can be removed, reducing
the overall depth of the assembly and the footprint of
the mount on the wall. Further, the assembly includes
a weather resistant input connection cover to protect
the 5-way binding post input terminals.
