CWM7.5 S2

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 Flowport™ for an
outstanding bass response from a relatively small footprint. It has a
critically formed baffle constructed from glass-reinforced ABS plus its own
integrated back box, 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.
