Black Anodised Aluminium
Ceramic-Coated Aluminium/Magnesium is a material originally developed by the aerospace industry for jet engine components. Its properties are ideal for loudspeaker cones being extremely rigid, yet light enough to yield high overall efficiency. In manufacture, aluminium/magnesium alloy undergoes a three-stage stress-relieving process to remove surface deformation and molecular weakness. Once formed, the alloy cone is subjected to a high temperature anodic coating process in which a layer of pure ceramic alumina is depleted onto its surfaces to a depth of 50 microns, producing a completely rigid sandwich of alloy and heat-dissipating ceramic material.
Conventional cones are liable to flex or twist in operation, producing a significant level of audible distortion. C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range. C-CAM tweeters and woofers share an audible consistency producing a smooth transition of frequencies and a sense of realism and cohesion in the soundstage.

Shadow with Substance
They’re great to look at, but there’s so much more to our super-skinny Shadow on-wall speakers than meets the eye. We’ve taken our best audio technologies and optimised their performance for the demands of the slimmest cabinets. This means that even though the wall-hugging Shadow speakers are a mere 40mm in depth, they generate the full frequency sound of a much larger design. Our confidence is confirmed by the latest review, from Sound and Vision magazine, which says that the Shadows play ‘loud, clean and clear’, with ‘excellent volume output for their size’, concluding that ‘the Monitor Audio Shadow series speakers play really loud and sound really good. Yeah, on-walls are still a compromise, but when you hear these, I think you’ll agree that the compromise is minimal.’
