Reference Custom Theatre Passive Subwoofer
Extreme depth and absolute control for dedicated cinema rooms
The B&W CT8 SW is the flagship passive subwoofer in the Custom Theatre CT8 series, designed to deliver deep, powerful, and perfectly controlled bass extension. Designed for professional-level home theater installations, it delivers extraordinary physical impact and extremely precise response even at the lowest LFE frequencies.
The sealed enclosure (Acoustic Suspension) configuration ensures fast, dry, and bass-free bass, allowing for seamless integration with the CT8 LR and CT8 CC speakers. It's the ideal choice for large dedicated theaters where you want to recreate an authentic and immersive cinematic experience.
Professional design and maximum dynamics
The CT8 SW integrates a powerful 380 mm (15") long-throw woofer , developed to handle high sound pressure levels while maintaining control and precision. The reinforced cabinet reduces unwanted vibrations and resonances, improving signal clarity and transient definition.
Designed to be paired with dedicated CT Series amplifiers, it enables multi-subwoofer configurations for even low-frequency distribution and linear response throughout the room. The B&W CT8 SW represents the ultimate solution for reference-level home theater systems.
