Bowers and Wilkins CWM-8180 Brochure
CWM 8180
See nothing, hear everything
If three-way in-wall speakers are unusual, then one with the design and performance of the CWM 8180 is rare indeed. The CWM
8180 is a genuine high technology, high performance hi-fi speaker - it just happens to mount in a wall. Its driver line-up reads just
like one of the 800 series: 200mm Rohacell® bass driver, 130mm Kevlar® cone FST midrange driver and 25mm Nautilus™ tube
loaded aluminium dome tweeter - they give the CWM 8180 a real sense of musical authority and accuracy.
