The CCM663 is a true high-performance ceiling-mount speaker. The tweeter has a 25mm (1in) aluminum dome and its housing pivots for an adjustable off-axis treble response. The bass/midrange driver’s die-cast chassis provides extra rigidity which results in a cleaner, faster bass, and a three-position EQ switch for a better off-axis response. The Aramid fiber cone means that the unit is well hidden behind the grille but still produces a remarkably clear and dynamic sound. Incorporating QuickDogs™ and plug-and-play functionality it is quick and easy to install.

Video Review:

Highest quality sound – from above
With speakers in studios around the world, including Abbey Road, Bowers & Wilkins have an outstanding reputation for sound quality. Featuring a Nautilus, swirl loaded, aluminum tweeter, and blue Aramid Fibre woofer, the CCM663’s speaker spec matches its top-quality cabinet speakers. The Nautilus provides exceptional detail and crisp and uncompressed response, right the way to 50,000Hz. The Aramid Fibre cone matches power and control for exceptional realism.

Tilt-adjustable tweeter for precise detail
Fitted with pivoting tweeters in both speakers, getting the perfect soundstage is easy with these Bowers & Wilkins ceiling speakers. The tweeters tilt by up to 30 degrees, letting you angle them to precisely the best spot – usually your sitting area in the room. The more directly aligned the tweeters are with your ears, the more detail you hear – simple!

Optimised EQ
Working with the adjustable tweeters, the three-position equalizer optimizes the response for superior off-axis sound. This means that, even when you’re not in the listening ‘sweet spot’, you’ll still get the best-balanced sound possible.

Unobtrusive design
Once in place, these easy-to-fit ceiling speakers look sleek and unobtrusive. The flush-fitting grilles offer an ultra-low profile against your ceiling and can be painted to harmonize with your décor.
Don’t sacrifice sound quality for convenience – with the Bowers & Wilkins CCM663 they go hand-in-hand.
