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.

803 specifications

The Bowers & Wilkins 803 loudspeaker is a prime example of high-end audio engineering, renowned for its exceptional performance and elegant design. Part of the 800 Series, which has been celebrated by audiophiles and music professionals alike, the 803 combines advanced technologies with a refined aesthetic.

One of the most notable features of the Bowers & Wilkins 803 is its innovative driver technology. It utilizes a 30mm Carbon Dome tweeter that provides clear and detailed high frequencies, ensuring that even the subtlest nuances in music are preserved. This tweeter is positioned above the mid-range drivers in a unique design known as the "tweeter-on-top" configuration, which minimizes distortion and ensures an accurate soundstage.

The mid-range drivers in the 803 are crafted from a proprietary material called Continuum, which offers improved response and lower coloration compared to traditional materials. This allows the speaker to deliver a rich and warm sound while maintaining clarity and precision across a broad range of frequencies. The bass performance is powered by dual 8-inch Aerofoil woofers, designed with a variable thickness profile to reduce distortion and provide powerful, articulate low-end reproduction.

Another significant technological advancement in the Bowers & Wilkins 803 is its use of Flowport bass reflex design. This feature enhances airflow and reduces turbulence, resulting in deeper, more controlled bass that enriches the listening experience. The cabinet construction also plays a crucial role in sound quality. The 803's enclosure is rigid and carefully braced, minimizing resonance and vibrations that can detract from audio performance.

Aesthetically, the Bowers & Wilkins 803 is stunning. Available in various finishes, including rosenut, walnut, and gloss black, it is designed to seamlessly blend into any environment while making a bold statement. The speaker's sleek lines and premium materials exude sophistication, making it a statement piece in any home.

In terms of connectivity, the Bowers & Wilkins 803 is versatile, allowing it to be used with a variety of audio setups and equipment. Whether you're a casual listener or a dedicated audiophile, the 803 delivers an immersive experience that brings music to life with astonishing realism and depth. With its combination of innovative technology, premium materials, and stunning aesthetics, the Bowers & Wilkins 803 sets a new standard for high-end loudspeakers.
