B&W CWM7.5S2

See nothing, hear everything
The CWM7.5 shares the acoustic configuration of the 707 S2 and like its sibling, it
houses a 130mm (5in) bass/mid-range Continuum cone driver plus a 25mm (1in) Carbon
Dome tweeter, coupled to a forward-firing FlowportTM for outstanding bass response
from a relatively small footprint. It has a critically formed baffle constructed from glass
reinforced ABS plus its own integrated backbox, ensuring retrofittable installation plus
optimum performance. It’s an outstanding performer when used in stereo or multi-room
installations, and is equally at home as the rear speaker in a larger theatre application.
