Voorgangers van de 805 matrix / nautilus topmonitoren. 2 Weg gesloten systeem volgens het beroemde door bowers & wilkins gepatenteerde matrix principe. Akoestisch “dode” celstructuur. Kenmerkt zich door volledig neutrale en zeer strakke weergave en vrijwel afwezige eigen resonantie. De kast is door zijn stijfheid zo dood als een pier waardoor er absoluut geen resonanties het geluid kunnen beinvloeden. Dit hoor je onmiddelijk in ongelofelijke dynamiek, snelheid en neutraliteit. In bijna alle reviews werd opmerkelijk lang stilgestaan bij de vraag hoe deze weergevers zo neutraal en exact kunnen klinken; kleuring is gewoonweg niet waarneembaar. Zeer evenwichtige klank.

The B&W Matrix loudspeaker system incorporates the first radical improvement in enclosure design for many years. Invented by Laurence Dickie (B&W Chief Electronics Engineer) it is an ingenious new type of construction, concealed within the loudspeaker cabinet. This unique construction - the B&W Matrix - virtually eliminates cabinet vibrations, which in ordinary loudspeakers add their unwanted contribution to the final sound.
This is a monitor quality loudspeaker system capable of generating extremely high sound levels. At the same time, due to its wide and balanced frequency response, it will faithfully reproduce the quieter sounds of a solo instrument requiering considerably lower sound level for a faithful reproduction of the live performance.
Quite deliberately, the B&W matrix series of loudspeaker are described as digital monitors. They have been designed for the age of the compact disc, with all the additional reqirements that this material places on the loudspeaker system - such as increased dynamic range, increased transient information, lower noise floor, etc.
B&W Matrix is, however, just as mich at home with good analogue material and essentially will faithfully reproduce whatever signals are fed to it.
The loudspeaker drive units
Having made this major breakthrough in enclosure design, B&W used their ongoing research programme to incorporate totally new drive units within the Matrix series of loudspeakers. For the bass and bass/midrange units, anew material - homopolymer polypropylene - was chosen. A ferrofluid design was employed for the high frequency transducer, giving an additional 8 dB of clear dynamic range for the increased transient signals of the compact disc.

Crossover, filter network and protection circuits
In any product, when the designer improves one module, others have to be upgraded if the whole is to be superior. Take the example of a car for which a new, improved engine is developed; better brakes and suspension must then complement the improved performance from the power unit if the car is to be a totally better product. Likewise with the B&W Matrix series of loudspeakers: having improved both the enclosure and the drive units, corresponding improvements were necessary both in the components and design of the crossover. The APOC protection circuit on which B&W hold world patents, has also been upgraded.

The B&W Matrix enclosure.
The newly invented Matrix enclosure, on which patent applications are pending throughout the world, is the heart of this loudspeaker and represents on of the few new inventions related to loudspeaker enclosures for many years. The B&W matrix or honeycomb structure which fills tha air space inside the cabinet prevents the enclosure (as opposed to the loudspeaker drive unit) from radiating sound, almost completely. This has never before been achieved.
