The cone is made with nature-proof high-stiffness pressed paper featuring innovative water/humidity resistance and anti-UV treatments. The double-layer copper voice coil wound on a polyimide former ensures unparalleled power handling. New motor units are made of special Neodymium N38 H to obtain a minimum bulk and increased performance.
The provided MPG 690 grille is made of a high-resistance ABS plastic structure with a metallic finish and a protective metal mesh.
