KEF Blade – NEW


SKU: N/A Category:


BLADE is the top model in the range with four 225mm/9in. bass drivers and a Uni-Q MF/HF array in a 1590mm/62.5in. high cabinet.

BLADE is the world’s first Single Apparent Source loudspeaker and the production version of the cost no object Concept Blade project KEF revealed at the Munich High End Show in 2009.

KEF’s groundbreaking Uni-Q driver arrangement operates by housing a discrete tweeter in the center of the mid-range (treble/bass) unit. This allows both the entire sound field created by the speaker to originate from a single point in space, meaning every sound in the entire spectrum reaches your ears with precise alignment. This produces a truly natural sound; a sound capable of convincing the listener they are hearing a live performance. Because the audio originates from a single point, you can stand anywhere in the room and hear a performance more precise and realistic than other speakers can provide.
