Bowers & Wilkins CCM7.5 S2 In-Wall Speakers

-- See nothing, hear everything --

The CWM7.5 S2 share 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 B&W trademarked forward-firing Flowport for outstanding bass response from a relatively small footprint. It has a critically formed baffle constructed from glass reinforced ABS plus its own integrated and expandable back-box, ensuring retro-fittable installation plus optimum performance. It's an outstanding performer when using in stereo or multi-room installations, and is equally at home as the rear speaker in a larger theater application.
