Bowers & Wilkins CT8 SW Closed-Box Subwoofer with 1x15" Rohacell Bass Speaker

Integral to the system’s no-compromise approach to bass management is the subwoofer, illustrated here with a pair deployed at extreme left and right for low frequencies that will push your sound envelope to the limit. The CT8 SW features a 15” driver. Like all the bass drivers in the range it features a rigid composite sandwich cone.

Bass drivers

As you might imagine, one of the secrets of developing a high performance bass driver is finding a cone material with high enough strength to keep its shape under the heaviest of strain, yet not too heavy that it loses its responsiveness. B&W’s choice is a modern carbon fibre and rigid foam sandwich construction used in car and aircraft bodies. Its outstanding mechanical properties and relatively low mass make it tailor-made for the job of turning low frequency effects into real-life sound.
