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.
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.
