The new Bowers & Wilkins CI800 Series Diamond range of custom installationspeakers 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. Despite their dramatically enhanced performance, every new model fits into the backboxes and apertures of the outgoing CI800 Series, so owners can easily upgrade to the dramatically improved performance offered by the new range. The result is outstanding levels of performance that once again raise the bar for custom installation loudspeakers.


For the fi rst time we have incorporated Diamond dome tweeters into custom installation speakers. Exceptionally light yet unbelievably rigid, the Diamond dome delivers pure, distortion-free treble.


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 fl agship 800 Series Diamond and delivers pristine midrange performance.


First developed for the 800 Series Diamond, Aerofoil cones deliver incredible bass performance. The ultra-light yet exceptionally stiff Aerofoil design combines a computer-optimised form, carbon-fi bre outer ‘skins’ and a light syntactic foam core to ensure accurate, punchy bass.


The Diamond dome tweeters and midrange drive units in the new CI800 Series Diamond are fully decoupled from the body of each loudspeaker in a similar way to the drive units in the 800 Series Diamond. This minimises the impact of resonance through the baffl e caused by the operation of each drive unit and results in a sound that is cleaner and more accurate.
