BLADE
BLADE, the world's first Single Apparent Source loudspeaker, is the production version of the famous Concept Blade project KEF revealed at the Munich High End Show in 2009.Features
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
