SB Series

Lowest of the Lows

Our design innovations aren’t limited to our screen channel loudspeakers.  We also offer industry-leading subwoofers and surround loudspeakers:

 

DCS subwoofers are available in a variety of single and dual 18-inch driver enclosures.

When 18-inch woofers aren’t quite enough, the ultra bottom-end is covered with the awe-inspiring 21-inch SB-15121.

Our Subwoofers bring earth-shaking realism to the cinema experience, driving home the impact of explosive soundtrack action. Our high quality MDF and plywood 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. With both single- and dual-driver models to choose from, our subwoofers excel at clean, punchy lows, delivering excitement you can feel to every seat.
