The new Bowers & Wilkins CI800 Series Diamond range of custom installation speakers is engineered for discerning customers who demand great hi-fi and home cinema sound from loudspeakers that occupy minimal space. This exceptional range of in-wall and in-ceiling loudspeakers features all the key transducer technologies developed for the globally renowned 800 Series Diamond including Diamond dome tweeters, Continuum midrange drivers and Aerofoil bass cones. The result of outstanding levels of performance that once again raise the bar for custom installation speakers.


Audiophile performance
CCM8.5 D is a two-way in-ceiling loudspeaker which offers high-quality acoustics in an incredibly discreet package. It features a decoupled Diamond dome tweeter and a single 7inch bass/mid Continumm driver with anti-resonance plug. All the drive units are located in a rotatable mini-baffle which allows the user to ‘toe in’ the drive units of the loudspeakers for the best performance. For optimum discretion when installed, the Continuum cone is given a dark finish.

The quality of the CI800 Series Diamond drive units is such that we’ve been able to make speakers first-oder crossover one of the simplest – and best – we’ve ever produced. Using the same exceptional handpicked components found in the flagship 800 Series Diamond.


Diamond tweeter
All the knowledge and experience gained during the development of the revolutionary 800 Series Diamond has been transferred in to the CI800 Series Diamond. It’s the best-performing series of custom installation loudspeakers we’ve ever produced. Incredibly light, yet unbelievably rigid, diamond is the ultimate tweeter material. By distorting less than conventional materials, such as aluminium, the diamond dome pushes away the moment of first break-up from the 40kHz of the out-going range to well over 70 kHz. Delivering the most revealing, natural treble you will ever hear.

Acoustic volume
One of the biggest challenges facing Bowers & Wilkins engineers is translating the high-performance of the 800 Series Diamond to the CI800 Series Diamond range was ensuring a consistency of acoustic volume. A great deal of time has been spend optimising materials to get the stiffest possible structure, and listening to the results.

The CI800 Series Diamond features the new Continuum cone, our remarkable new midrange driver technology. The result of an eight-year research and development project, Continuum was introduced in our flagship 800 Series Diamond and delivers prestige midrange performance.

Rotating baffle
The drive units are located in a rotatable central baffle, for toeing-in the loudspeaker.

Ease of installation
CI800 Series Diamond features back boxes that are fully Matrix™ braced, for extra rigidity and improved performance. The back boxes feature bi-wirable cables that are guided to the terminal panel through tubes and connect to the baffle electronically with a multi-pin connector. Despite their dramatically enhanced performance, every new model fits into the back boxes and apertures of the outgoing CI800 Series, so owners can easily upgrade to the dramatically improved performance offered by the new range.

The back boxes also connect to the baffle electronically, with a multi-pin connector.

The back boxes feature high quality bi-wirable cables that are guided to the terminal panel through tubes.

Bowers & Wilkins CI800 Series Diamond
Each of our Custom Installation speakers has been developed with the same care and attention that we lavish on our more conventional, cabinet-based designs. Thanks to 50 years of experience in speaker development and our ongoing investment into science and technology we continue to lead the way when it comes to sound quality. Our CI800 Series Diamond is no exception.

For decades, the pioneering innovations developed at Bowers & Wilkins have influenced the way speakers are designed and built all over the world. Technological advances that can be found wherever sound quality matters, including top recording studios such as Real World Studios and Skywalker Sound Studios.
