AD-S282H

AcousticDesign™ Loudspeaker

The QSC AcousticDesign
AD-S282H is a full range, surface
mount loudspeaker with a sleek,
contemporary styling that fits
perfectly into multiple surroundings
and applications including hotels,
restaurants, convention facilities,
and multimedia environments.
The speaker incorporates the
Advanced Directivity rotatable
waveguide. Available in black or
white, these weather resistant
enclosures can be painted to
match any specific décor.

The AD-S282H is a 2-way system
housed in a ported enclosure
made from injection molded, high­impact polystyrene. This enclosure
incorporates two 8" weather
resistant, LF transducers with heavy­duty double roll cloth surrounds.
These high output versions employ
a 1" exit compression HF driver.
The HF driver is coupled with
QSC’s unique Advanced Directivity
rotatable waveguide—enabling the
loudspeaker to deliver accurately
focused sound, regardless of its
mounted orientation.
