Description
The Bowers & Wilkins BB CWM8.5 is a purpose-built backbox engineered to optimise the acoustic performance and structural stability of the CWM8.5 in-wall loudspeaker. Designed for premium custom installation projects, this enclosure ensures controlled sound reproduction, reduced resonance and long-term reliability within a compliant wall structure.
Acoustically Tuned Enclosure
The BB CWM8.5 provides a dedicated internal volume that allows the CWM8.5 loudspeaker to perform at its full potential. The rigid backbox construction enhances bass accuracy, improves clarity and prevents unwanted vibration — essential for achieving high-fidelity audio in architectural spaces.
Secure and Precise Installation
The installation process includes mounting brackets and multiple fixing points for secure positioning between wall studs. As shown in the official diagrams (pages 2–4), the backbox is designed for a stud spacing of 1088 mm and supports proper alignment and structural reinforcement during wall construction. This ensures a stable foundation for the loudspeaker and compliance with building and wiring guidelines.
Integrated Cable Management
Cable entry points and strain-relief fittings allow safe and organised wiring. The manual highlights a recommended cable drop clearance of 600 mm (page 3), supporting clean and accessible routing during installation.
Architectural Dimensions
According to the technical drawings on page 5, the BB CWM8.5 features:
-
Height: 1088 mm
-
Width: 347 mm
-
Depth: 90 mm
-
Rear mounting aperture height: 395 mm
These precise dimensions ensure predictable integration into stud-wall cavities and alignment with the CWM8.5 front baffle.
Safety & Compliance
The BB CWM8.5 meets EU Electromagnetic Compatibility and General Product Safety directives, as outlined in the Declaration of Conformity (page 6). This guarantees long-term operational safety and adherence to industry standards.
