Kevlar is a synthetic aramid fibre, manufactured by DuPont, and probably best known for its use in bulletproof vests. Indeed, those same mechanical properties of strength and the ability to dissipate the energy of a bullet also have benefits for speaker cones. Bowers & Wilkins first started using Kevlar as a cone material in 1976.

This is a good thing for we will be watching Iron Man 2 on the big screen tonight. On B&W speakers. With Kevlar cones.
