C-CAM® Drivers
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.
IDC®
The in-ceiling and in-wall LCR models employ a unique pivoting Inverted Dual Concentric midrange/tweeter module offering up to 18 degrees of play. This allows for the speakers to be discreetly positioned and the sound to be directed toward the listening zone by pivoting the IDC driver module to maximize performance. With the IDC module installed, these architectural speakers become true 3-way designs, offering superior performance and flexibility over typical 2-way or fixed angle speakers.
Within the proprietary IDC module an inverted 4" midrange driver provides superior dispersion while enabling the midrange cone and tweeter dome assembly to be set as far forward as possible, allowing a clear acoustic 'sighting' of the desired listening zone and reducing undesirable diffraction effects. It's impossible to avoid diffraction effects from conventional two-way designs, which locate the bass driver 75mm (3") to 150mm (6") behind the speaker grille.
Gold Dome C-CAM®
The gold dome tweeter is formed from a ceramic-coated aluminium/magnesium alloy, gold anodised to a specific thickness for ideal stiffness and damping characteristics. Its new profile and surround geometry have been developed using advanced modelling tools, to provide the optimum qualities for accurate sound reproduction. The new design moves the first order of breakup to beyond 35kHz, producing a linear response way beyond audibility, which matches the wide frequency bandwidth available from HD music and cinema sound formats.
The gold dome is thinner, lighter, more rigid and therefore more efficient than domes made from other materials which are prone to distortion in the audio band.
