Bowers & Wilkins - CT Series 12" Passive Subwoofer - Black

The CTSW12 is a passive subwoofer featuring a paper drive unit. All CT SW subwoofers have a closed-box design that makes them easy to install in cabinetry. It might seem strange to many listeners that a material like paper could have much to do with a product as solid and powerful as a Custom Theater subwoofer. Nevertheless, paper plays a vital part in what they're hearing.
