KEF is named after Kent Engineering and Foundry where our story began. Our founder Raymond Cooke was propelled by a love of music and a refusal to compromise, and he leveraged technology at every turn to ensure KEF’s position at the cutting edge of audio.
A list of breakthroughs spanning more than half a century shores up that promise; a walk to match the talk. Patents and academic papers alike testify to decades of consistent progress, from the early use of synthetic materials to our Reference Series which determines industry standards to this day. KEF’s insistence on excellence is at the heart of a virtuous circle, which attracts the world’s most gifted acoustic engineers to join us in the pursuit of good, better, best.
