Bowers & Wilkins CWM663 In-Wall Loudspeakers

The CWM663 is one of Bowers & Wilkins more adept in-wall models and utilises a high-quality blue Kevlar bass/midrange cone. This cone sits within a die-cast chassis, providing additional rigidity which in turn results in a cleaner, more dynamic bass response. The tweeter has also been thoroughly thought-out, comprising of a light, aluminium material and incorporating a Nautilus tube to absorb unwanted sonic radiation. 

A three-position high-frequency switch is integrated into the speaker itself, allowing you to adjust the sound of the speaker depending on the application or acoustic environment. It's quick and easy to install, thanks to B&W's innovative QuickDogs plug-and-play installation functionality.
