The precision cast, machined and Graphene treated magnesium cone acts as a piston through the working frequency band without showing any sign of midrange resonances. A titanium voice coil former with a long copper winding for excellent force transfer, transient sound reproduction and large linear excursion. A unique radial reinforced rubber surround reduces radial resonances and prevents surround break up at large excursions. This combination results in very low mechanical damping for better clarity and brings out the micro details in the music. An FEA optimised magnet system with precisely fitted copper parts for excellent linearity, high power handling and low distortion. The extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
