QSC Cinema DCS-SB-7118

Description

Part of the DCS Digital Cinema Speaker Series, QSC’s SB-5118 and SB-7118 subwoofers offer a unique solution that addresses the requirements of digital motion picture soundtracks. Featuring a high excursion, 18” low-frequency transducer mounted in ported enclosures, these systems extend response to the lowest audible frequency. The two custom 18” transducers were developed especially for cinema use. The woofers feature 4” voice coils and vented pole pieces to ensure cool operation, even at high power levels. Cooler temperatures increase driver lifespan and decrease power compression at high drive levels. Undercut pole pieces provide a symmetrical magnetic gap, reducing second harmonic distortion. Enclosures are constructed heavily-braced high-quality MDF Panels.
