Precision cast, machined and Graphene treated magnesium cone acts as a piston throughout the audible frequency band without showing any sign of midrange resonances.
Titanium voice coil former with a long copper coil winding for excellent force transfer, transient sound reproduction and large linear excursion. 
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.
Gold plated terminals mounted on a glassfibre reinforced plate to reduce contact resistance and improve reliability.
