Bowers & Wilkins CT8SW Subwoofer

Yes, the CT8 SW is a passive subwoofer, meaning it does not have a built-in power source. You will need to pair it with a compatible external amplifier to drive the 15-inch driver effectively.

While it is specifically engineered to integrate seamlessly with the CT8 LR speakers for a cohesive home theater setup, it can be used in other high-end custom installations. However, you will need to ensure your processor and amplification are calibrated correctly to match the subwoofer's performance characteristics.

Rohacell is a high-strength, lightweight foam material used in aerospace applications. In this subwoofer, it creates a rigid composite sandwich cone that resists bending under pressure, allowing for precise, distortion-free bass even at high volumes.

The Matrix bracing system acts like an internal skeleton for the cabinet, significantly increasing its rigidity. This minimizes unwanted cabinet vibrations and resonance, ensuring that the sound you hear is pure, tight bass rather than rattling or coloration from the enclosure itself.

The CT8 SW is designed for custom in-wall integration, but because of its 70-liter enclosure and robust build, it requires a dedicated space within your wall structure. We recommend consulting with a professional installer to ensure your wall can support the weight and that the cavity is properly prepared for the enclosure.

The CT8 SW is capable of extending bass response down to 13Hz. This is well below the range of human hearing, providing a physical, tactile experience that you feel in the room as much as you hear.
