DESCRIPTION

KEF’s BLADE series is an altitude. It’s all about exploring the art of possible music – without any preconceptions. The BLADE snow-white speaker is the result of KEF’s brightest and best engineers being given free rein to create the ultimate speaker without design or cost limitations. The BLADE speaker concept took decades to come to fruition. But resulted in a speaker that looks and sounds like no other speaker. It is a product that music lovers can own and enjoy!
