Bowers & Wilkins, was originally a British company that produces consumer and professional loudspeakers and headphones. It was founded in 1966 by John Bowers in Worthing, West Sussex, England.

Some key innovations of Bowers & Wilkins over years include:

The patented use of Kevlar fibres, impregnated with a stiffening resin, resulting in B&W’s distinctive yellow speaker cones started in 1974. This composite material proved to provide controlled rigidity and internal damping, minimising distortion, as Fryer determined by using laser interferometry on speaker cones.

Phase linear transmission was realised in the DM6 from 1976. In the DM6, the speakers are mounted in different vertical planes.
In 1977 the DM7 introduced a tweeter separate from the main speaker cabinet. This has been a feature of many B&W speaker designs since.
Dickie invented the ‘Matrix’ enclosure which reduces cabinet sound colouration. This bracing topology resembles a wine-case, providing multiple thin panel-braces, spaced throughout the enclosure, improving rigidity. This was in response to Celestion’s SL6000 loudspeaker that was made with Aerolam cabinet walls. Dickie’s response was to use the same concept but make it all the way through the cabinet rather than just the walls. Matrix has been used with great success by B&W ever since.

The ‘Nautilus’ speaker resulted from research commenced by Bowers into ‘perfect dipoles’. Before Bowers died, he handed this research to the young Dickie who discovered the principle of the exponential tapered tube. The Nautilus project was one of the most extensive research and development projects undertaken. Instead of open-backed drivers, it uses drivers loaded by reverse-tapered horns, or exponentially diminishing tubes, to absorb the rear radiation. The construction is based on fibre-reinforced plastic enclosures. The result of the distinct speaker shape was a near perfect response and near-zero enclosure colouration.

The ‘Flowport’ is an improvement that reduces friction in the air moving through the bass reflex vent. This is realised by covering the surface of the vent with dimples, just like a golf ball.

The diamond tweeter was developed to create the optimal ratio of tweeter dome mass and material stiffness. The tweeter is grown into shape by chemical vapour deposition.
