This results in high levels of force factor and power handling with an optimum power to weight ratio. A state-of-the-art Interleaved Sandwich Voice coil (ISV) copper wire voice coil provides high levels of thermal stability and durability. The transducer incorporates Eighteen Sound DSS technology (Double Silicon Spider), in combination with a single roll highly damped surround, that has been designed to provide symmetric large signal behaviour throughout the whole working range, providing low harmonic distortion at different excitation levels. The already low distortion and sound quality are further improved by properly positioned Single Demodulating Ring (SDR), that flattens impedance and phase curves helping a constant power transfer from the amplifier. The deep profile curvilinear cone, created from a special high strength wood pulp, has been designed to achieve the best possible linearity. The humidity repellent cone treatment significantly dampens bell mode resonances. A special coating applied to both the top and back plates makes the 12NW530 far more resistant to the corrosive effects of salts and oxidization.
