What customers say
Customers consistently praise the Bowers & Wilkins CWM 663 for its exceptional sonic clarity and detail, driven by its signature tweeter technology. A key highlight is the surprisingly robust and well-defined bass response, which exceeds expectations for an in-wall speaker. Reviewers value the seamless aesthetic integration, noting the magnetic grille allows the speakers to virtually disappear while delivering high-fidelity sound for both music and home theater. The build quality is universally regarded as premium and durable. While the investment is significant, the overwhelming consensus is that the uncompromising audio performance fully justifies the cost, making it a top choice for those prioritizing aesthetics alongside superior sound.
Know before you buy
The Nautilus™ tube-loading technology absorbs unwanted sound radiation from the back of the tweeter. This results in a much clearer, more detailed high-frequency performance compared to standard in-wall designs.
Yes, the CWM 663 features a three-position high-frequency switch. This allows you to fine-tune the treble output to better suit the acoustics of your specific room.
You will need a mounting depth of at least 95mm (3.7 inches) behind the wall surface. Ensure your wall cavity is deep enough to accommodate this before beginning installation.
QuickDogs™ is a spring-loaded mounting system that allows you to secure the speaker into the wall cutout without needing extra tools or complex brackets. It makes the physical installation process significantly faster and more secure.
These speakers are designed to handle up to 100 watts of amplifier power, making them well-suited for most home theater or high-fidelity stereo applications. However, they are best paired with an amplifier that can handle a nominal impedance of 8 ohms.
To ensure a proper fit, your wall cutout should measure 228mm (9 inches) in height by 153mm (6 inches) in width.
