Nautilus™ treble unit, Matrix™ cabinet and Flowport™ bass tube. • The Nautilus 803 cabinet is made up of layers of ply. The graceful curves of the cabinet are skillfully moulded layer by layer which helps to eliminate the unwanted resonances caused by flexing of flat and square cabinet walls. T Technical highlights Tweeter on top: B&W's Tweeter on top technology ensures that the sound remains focused and time-sensitive and that the stereo-lmage is presented with unparalleled three dimensional accuracy. Kevlar®: B&W developed and patented the method of using Kevlar® for loudspeaker cones to reduce unwanted standing waves. DuPont originally created Kevlar® for use in bulletproof vests. Flowport™: Golf ball aerodynamics theory points the way towards lower distortion reflex ports. Dimples improve the way the air flows over the surface of any object. In the case of reflex ports, they offer a significant improvement over simply flaring the port ends in reducing air flow turbulence at each end of the port; so you get less chuffing noise and less compression at high sound levels. Matrix™: The basic construction of nearly all loudspeakers is exactly the same -panels of wood-based materials, bonded to form a rectangular box. B&W studied and evaluated how each aspect of cabinet behaviour and the efficiency of various materials and construction methods affects sound.
