QSC SB-2180

Compact Cinema Subwoofer 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.

The SB-2180 features two 18" (457 mm) woofers with 4" (102 mm) voice coils for extended bandwidth low frequency reproduction. With an enclosure depth of less than 17 inches (452 mm), the SB-2180 is one of the narrowest dual-driver subwoofers available, which dramatically reduces space requirements behind the screen. A unique folded port design allows the enclosure to be extremely narrow, while maintaining full port length and volume.
