Bowers & Wilkins CWM663 (pair)


Bowers & Wilkins CWM663 In-Wall Speaker

The Bowers & Wilkins CWM663 features a 150mm (6in) blue Kevlar® bass/midrange driver housed in a die-cast chassis which provides the extra rigidity to provide a cleaner, faster bass.

An aluminium tweeter incorporates a Nautilus™ tube to absorb unwanted sonic radiation. The CWM663 also utilises a three-position high frequency switch to fine tune the sound. The incredibly easy to install frame includes QuickDogs™ and plug-and-play functionality.

The larger 6" Kevlar driver in the CWM663 makes it ideal for medium to large sized rooms where high quality, discrete sound is required. High sensitity means the CWM663's are easy to drive, making them an ideal match for the likes of Sonos, Bose and other multi-room audio systems as well as more traditional separate component systems.
