The Bowers & Wilkins CWM652 are a pair of in-wall speakers for the highest level of integrated home audio requirements. These sit at the top of the Bowers & Wilkins CI600 range alongside the CWM663s & provide the best performance & quality sound as a result. Being slightly smaller than the CWM663s they require a slightly lower amp power of 100W. These are a great option for when you need the best quality power in a slightly smaller spacce. Featuring a HF switch this speaker can be fine tuned for the best possible performance for your space.
