B&W CWM8.3

B&W CWM 8.3 is a three-way, in-wall loudspeaker, conceived to offer the very best performance for a customer requiring great sound, without seeing the source. It features a Carbon Braced Tweeter, a 5in Kevlar FST drive unit and two 7in carbon fibre reinforced Rohacell low frequency drivers. The central baffle is rotatable, so B&W CWM 8.3 can be used in either vertical or horizontal alignment.
