The CWM 7.3 S2 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 transducers, when combined with high-quality, optimized, components on the crossover and a critically formed baffle constructed from glass-reinforced ABS, produce a truly remarkable in-wall speaker.
