CWM7.3 S2 In Wall Speaker (Each)

In-Wall system with 703 S2 Performance Levels!

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 6" Aerofoil profile bass drivers, a 4" Continuum cone FSTTM mid-range driver and a Carbon Dome 1" 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.
