Bowers & Wilkins Floor-standing Loudspeaker System 803 Specifications

Nautilus 803
™
F l o o r-standing lou dspeak er system

Product Summary

Floor-standing design with a two in one cabinet construction, which reduces sound diffraction
between the bass and midrange. 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.
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-image 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.
