QSC SC-2150 – 3-Way 2x15-Inch Cinema Screen Channel Loudspeaker

Product Overview

The QSC SC-2150 is a three-way screen channel loudspeaker from the DCS Digital Cinema Series, developed for professional motion-picture playback in smaller cinemas up to 55 feet (16.6 m) in length. It offers high power handling, excellent sensitivity, and extended bass response in a compact enclosure.

Configurable as a selectable passive full-range or bi-amplified system, the SC-2150 pairs a horn-loaded midrange and compression driver with dual 15-inch low-frequency drivers for articulate dialogue and solid low end.

Product Description

The SC-2150 comprises two main units: a mid-high frequency system and a dual-15-inch low-frequency enclosure. The components assemble on-site via a pan-and-tilt bracket that mounts the mid-high section atop the LF enclosure, and QSC's patented CineSight simplifies aiming the horns for proper audience coverage.

The mid-high system features a high-output, horn-loaded 6.5-inch midrange cone driver and a 1.4-inch (35.6 mm) diaphragm compression driver. The heavily braced MDF low-frequency enclosure provides extended bass response, while a shallow 14.5-inch (368 mm) depth reduces the space required behind the screen.

Advanced crossover circuitry protects the HF and MF drivers from overpowering and excessive low-frequency program material. As part of the QSC DCS ecosystem, the SC-2150 integrates with QSC cinema subwoofers, surrounds, and cinema amplifiers and processors.
