Bowers & Wilkins CWM7.3 S2 (per piece)

The CWM7.3 S2 features an integrated backbox that optimises its performance, cuts down on sound transference through walls and also makes it easy to retrofit. Its design incorporates twin 150mm (6in) Aerofoil profile bass drivers, a 100mm (4in) Continuum cone FSTTM mid-range driver and a Carbon Dome 25mm (1in) tweeter, all proven technologies shared with the acclaimed 700 Series range of loudspeakers. These outstanding tranducers, when combined with high-quality, optimised, components on the crossover and a critically formed baffle constructed from glass reinforced ABS, produce a truly remarkable in-wall speaker.
