Nau tilu s™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.
