Bowers & Wilkins CT8 SW – Reference 15-Inch Passive Theater Subwoofer

The Bowers & Wilkins CT8 SW is a reference-grade 15-inch passive subwoofer engineered for exceptional low-frequency performance in dedicated private cinemas. Part of the prestigious CT800 Custom Theater Series, it delivers deep, controlled bass with the precision and dynamic authority required for demanding home theater installations.

Featuring a massive 15-inch Carbon Aerofoil bass driver, Matrix-reinforced cabinet, and sealed enclosure, the CT8 SW is designed to reproduce the most demanding cinematic soundtracks with exceptional accuracy and impact.

15-Inch Carbon Aerofoil Bass Driver

At the heart of the CT8 SW is a 15-inch (380mm) Carbon Aerofoil bass driver, engineered for outstanding rigidity and low distortion.

Its advanced composite cone construction maintains precise movement under demanding conditions, delivering powerful low-frequency effects without sacrificing detail or control.

Deep Bass for Reference Home Theater

The CT8 SW extends down to 18Hz (±3dB), reproducing the deep bass effects essential to a truly immersive cinematic experience.

Whether delivering the subtle atmosphere of a movie soundtrack or the full impact of an action sequence, the CT8 SW provides the scale and authority expected from a reference-level subwoofer.

Matrix Cabinet Construction

Bowers & Wilkins' Matrix cabinet bracing technology helps minimize unwanted resonance and cabinet vibration.

Combined with its rigid closed-box architecture, this construction provides controlled, articulate bass reproduction while maintaining exceptional structural stability.

Designed for Custom Theater Integration

Unlike powered subwoofers, the CT8 SW is a passive design requiring external amplification and appropriate active crossover configuration.

Its architecture allows professional installers to integrate the subwoofer with high-performance amplification, advanced bass management, and other CT800 Series loudspeakers.

Multiple CT8 SW subwoofers can be incorporated into larger theater systems to improve bass coverage and consistency throughout the listening area.
