B&W - CWM663

The CWM663 features a 150mm (6in) blue Kevlar® bass/midrange driver housed in a die-cast chassis, providing extra rigidity for cleaner, faster bass. The speaker also incorporates a 25mm (1in) Nautilus tube-loaded aluminium dome tweeter, and a three-position high frequency switch for acoustic fine-tuning. Installation is almost effortless, thanks to our new QuickDogs™ fixing system and plug-and-play connection.
