The speakers of the Diamond Surround Sound System include subtle illumination in the front and rear doors. Housed behind etched stainless steel, the Fibonacci patterned grille offers optimal acoustic transparency. Through the exactingly positioning of its speakers the Diamond Surround Sound System delivers a crystal clear and pure acoustic evenly spread in the whole interior, assuring a true 3D sound experience on all seats. Inspired by the Bowers & Wilkins iconic Nautilus speaker, spiralling diffusion channels soak up reflected sound from the rear of each drive unit, reducing resonance to a minimum.
