Audiophile Performance

CWM8.3 D is a three-way in-wall loudspeaker, conceived to offer the very best performance for a customer requiring great sound without seeing the source. It features a decoupled Diamond dome tweeter, a 5in Continuum FST midrange drive unit and two 7in Aerofoil low-frequency drivers.

CWM8.5 D is a two-way in-wall loudspeaker. It offers exceptionally high performance from a compact loudspeaker. It features a decoupled Diamond dome tweeter and a single 7in bass/mid Continuum driver with anti-resonance plug. For optimum discretion when installed, the Continuum cone is given a dark finish.


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 pristine midrange performance.


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


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

Diamond Tweeter

All the knowledge and experience gained during the development of the revolutionary 800 Series Diamond has been transformed in to the CI800 Series Diamond. It’s the best-performing series of custom installation speakers 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 40 kHz of the out-going range to well over 70 kHz. Delivering the most revealing, natural treble you will ever hear.

Rotating Baffle

The central baffle is rotatable, so CWM8.3 D can be used in either vertical or horizontal alignment.

Ease of Installation

CWM8.3 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.
