QSC DCS Subwoofers bring earth-shaking realism to the cinema experience, driving home the impact of explosive soundtrack action. Our high-quality MDF subwoofer enclosures feature large, fully radiused and flared ports that smooth airflow at high levels to minimize noise from port turbulence. Symmetrical spacing of ports relative to drivers creates uniform internal pressure to prevent distortion and damage. In dual-driver systems, the box is completely divided into single-woofer chambers for greater strength and rigidity, allowing each driver to function normally in the rare event that the other fails. Available drivers include two 18-inch models with 4-inch voice coils and a massive 21-inch model with a 6-inch coil. Vented pole pieces decrease power compression while keeping drivers cool for increased lifespan. With both single- and dual-driver models to choose from, DCS Subwoofers excel at clean, punchy lows, delivering excitement you can feel to every seat.
