SB-7218

Part of the DCS Digital Cinema Speaker Series, QSC’s SB-5218 and SB-7218 subwoofers offer a unique solution that addresses the requirements of digital motion picture soundtracks. Featuring dual 18” lowfrequency transducers 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.

Features

• SB-5218 features dual 500 W transducers

• SB-7218 features dual 700 W transducers

• Frequency range extends to below 25 Hz when used with the correct B6 filter

• DCM and SF-3 signal processors optionally available

• Enclosures feature vandal-resistant woofer mounting bolts

• THX™ approved for professional cinema applications
