Developed specifically for the unique requirements of
professional motion picture playback, QSC extends its
commitment to the cinema market with the introduction
of the SR-110B Cinema Surround Loudspeaker. As a
member of QSC's DCS Digital Cinema Speaker Series,
the SR-110B offers high-power handling, excellent
sensitivity, and extended bass response in a very
compact enclosure.
The SR-110B Cinema Surround Loudspeaker features
a high-power, long-throw 10" low-frequency transducer
coupled with a 1" titanium diaphragm compression
driver. The system's plywood enclosure features a
15º down angle baffle and Array Optimized Tuning
(AOT) for optimum frequency response. The 200 watt
continuous power rating and sophisticated crossover
provides absolute reliability.
The compact black enclosure with black grille blends
into any theatre decor. A new QuickMount bracket
design allows for fast, easy and secure installation. The
loudspeaker half of the bracket comes pre-installed
on each SR-110B. The QuickMount wall bracket
is purchased separately to allow shipment to the
job site ahead of the loudspeakers. A traditional
U-bracket is also available in lieu of the QuickMount
bracket system.
