Uncompromised Innovation

BLADE is an attitude. It's about exploring the art of the possible, without preconceptions. Pushing boundaries.

So we gave our most talented engineers carte blanche to create the best speaker they can, with no design or cost restrictions. After years of research and testing, what they came up with looked and sounded like no other speaker: Concept BLADE. Its startling acoustic precision was so acclaimed when it first broke cover that we spent two more years refining the concept to produce an edition that serious audiophiles could own and enjoy.

The result was so well received - and scooped so many prestigious awards to prove it - that we decided to take things even further and expand the BLADE range.

Sculptural and acoustically inert, the slender parabolic enclosures are engineered never to interfere with the purity of the output. Inside, you find ingenious new venting, bracing and wave management technologies. Every component operates so comfortably within its performance envelope that you experience noticeably more precise imaging than is possible with conventional speakers.

Just as KEF's philosophy has always been to innovate in pursuit of the most accurate and realistic sound, BLADE speakers are about perfecting a groundbreaking concept to delight people who really love music. Whatever your taste, BLADE and BLADE TWO are what all great design aspires to: being the best they can possibly be.
