In all subwoofers of the 600 series, the bass diaphragms are made from a rugged, thin blend of paper, Kevlar fibers, and resin, which provides the stiffness required to withstand the enormous physical forces exerted by the voice coil and the pressures inside the speaker. Distortion is minimized, while bass accuracy, power, and enjoyment are maximized.
