Bass and mid-range driver cones use RDT, a unique technology developed specifically by Monitor Audio’s engineers for the Platinum series of loudspeakers*. Designed to reduce mass and increase cone stiffness, RDT applies ultra-thin skins of C-CAM to a core of honeycomb Nomex®** material, creating a structure which is extremely light but incredibly rigid. At only 40µm thick, the C-CAM skins are half the thickness of a human hair, yet when bonded to the hexagonal honeycomb core they form an RDT cone, which is 150 times more rigid than a single layer of 200µm C-CAM alloy, but has a fraction of the overall mass. These properties allow the cone to operate as a lightning-fast piston for a clearer more natural sound. The cone’s new concave geometry has been refined by FEA analysis to provide a smooth frequency response and eradicate break-up.
