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.
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.
RST®
The RST cone profile comprises a radial pattern of surface dimples. Our simulations and listening tests have proved that the dimples significantly increase cone rigidity allowing C-CAM/RST cones to resist mechanical bending forces, which can twist the shape of lesser cones and produce distorted sound. The strengthening effect of the RST dimples means that we can use thinner, lighter more responsive C-CAM cones, providing speed and accuracy but offering greatly reduced distortion. The RST dimples also help to displace standing waves that can propagate on the cone's surface.
