The midrange is where the real musical action is invariably found, and a smooth midband is an invaluable loudspeaker quality. Enter Kevlar. It’s been Bowers & Wilkins’ cone material of choice since 1974, and with good reason. The basic woven fabric is first impregnated with a stiffening resin that cures during the cone forming process. The cone is then further treated with a polymer coat, which seals the fibres and adds damping. The result is a semi-flexible cone, which exhibits a peculiar style of break-up behaviour, not found in more conventional materials, that maintains a more constant dispersion pattern at all frequencies in its range and transmits far fewer delayed, time-smearing sounds to the listener. Not only does it deliver a cleaner sound, it can do so to a wider group of listeners.
