Qsc-audio Cinema Surround Loudspeaker SR-18 User Manual download pdf

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-18 Cinema Surround

Loudspeaker. As a member of QSC’s DCS Digital

Cinema Speaker Series, the SR-18 offers high-power

handling, excellent sensitivity, and extended bass

response in a very compact enclosure.

The SR-18 Cinema Surround Loudspeaker features a

high-power, long-throw 8" 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 100 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-18. 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.
