Designed for down-firing, in-ceiling use, CCM7.5 S2 can be used as the left, centre, right and rear-channel speakers in a discreet home cinema system or as a High quality Audio speaker in a conventional 2 speaker HiFi system. Its configuration includes a 25mm (1in) Carbon Dome tweeter and a 180mm (7in) Continuum cone mid/bass cone angled to the mounting surface, allowing for easy direction of the whole array towards the listener to ensure they hear the correct balance of sound. That way, dialogue is crystal clear and special effects come across accurately. Thanks to Bowers & Wilkins unique QuickDogsTM fixing method, installation is simple and if preferred, the supplied round grille can be replaced with an optional square grille.
