CI 800 Series Diamond

The range

A new standard for custom installation loudspeakers

CI800 Series Diamond is a range of no-compromise in-wall and in-ceiling loudspeakers aimed at the most discerning listeners.

The new Series replaces the CI800 range of loudspeakers model-for-model and the new products have been specifically developed to fit into existing apertures in walls or ceilings, so owners of the older designs can easily upgrade to the latest generation should they wish.

CI800 Series Diamond shares all the key transducer technologies found in the 800 Series Diamond range of loudspeakers. This includes:

Diamond Tweeters

The most accurate high-frequency drive unit available, the Diamond Tweeter extends the point of first break-up way beyond the audible range (up to 70kHz). This exceptionally stiff and light diaphragm ensures pure, distortion-free treble.

Continuum Cones

The CI800 Series Diamond features the new Continuum cone, our remarkable new midrange cone technology. Replacing our iconic KevlarTM cone, Continuum is the result of an eight-year research and development project and was first introduced to the world in 2015 in our flagship 800 Series Diamond loudspeakers. Its supremely low noise ensures exceptionally clean and transparent midrange performance.

Aerofoil Bass Drivers

CWM8.3 D, the three-way model in the CI800 Series Diamond range, uses twin Aerofoil cone low-frequency units. These ultra-light yet exceptionally stiff low-frequency drivers feature carbon-fibre skins encapsulating a syntactic foam in an all-new computer-optimised curved geometry. Originally developed for the 800 Series Diamond range, Aerofoil cones deliver incredible bass performance.

CCM 8.5D £2350.00 each

CCM8.5 D is a two-way in-ceiling speaker. It features a decoupled Diamond dome 25mm (1 inch) tweeter and a single 180mm (7-inch) bass/mid Continuum driver. The drivers are located in a continuously rotatable mini-baffle which allows the user to ‘toe in’ the drivers for the best performance.

CCM8.5 D is engineered to deliver high-performance sound from a relatively compact ceiling-mounted loudspeaker. It features a decoupled Diamond dome 25mm (1 inch) tweeter and a single 180mm (7-inch) bass/mid Continuum driver.

The most accurate high-frequency drive unit available, the exceptionally stiff and light Diamond diaphragm ensures pure, distortion-free treble. CCM8.5 D also includes a dark Continuum bass/mid driver for pristine midrange and low end sound. Both drivers are located in a continuously rotatable mini-baffle which allows the user to ‘toe in’ the drivers for the best performance.

CCM8.5 D’s back box is fully Matrix™ braced, for extra rigidity and improved performance. The back box also includes bi-wirable cables that are guided to the terminal panel through tubes and connect to the baffle with a multi-pin connector. CCM8.5 D has also been developed to fit into existing back boxes enabling customers who purchased the original CCM8.5 to easily upgrade.
