BL ADE A BOLD AND STRIKING PRESENCE, BL ADE PUSHES THE BOUNDARIES OF WHAT IS POSSIBLE WITH SOUND. THE WORLD’S SINGLE APPARENT SOURCE LOUDSPEAKER NOW WITH KEF’S INNOVATIVE METAMATERIAL ABSORPTION TECHNOLOGY

A SOUND STATEMENT AN ICON THAT ENGAGES EVERY SENSE

UNCOMPROMISED INNOVATION Blade is an attitude. It’s about exploring the art of the possible, without preconceptions. FROM CONCEP T TO RE AL ENJOYMENT Obsessed with sound quality and The concept was further refined The latest Blade consists of two committed to bringing a superior models: Blade One Meta and Blade listening experience, KEF has been in 2011, when Blade became Two Meta. Both sharing the same pioneering innovative acoustic HiFi loudspeakers that serious audiophiles could actually own. Like same striking aesthetic, Blade Two we gave our engineers free rein the original Blade, a...

Blade set out to extend the boundaries of what high-end audio can achieve. Its exceptional acoustic integrity derives from the combination of carefully chosen components, new high performance drivers designed to behave with no break-up or resonance over their required frequency range and an inert, radically shaped cabinet engineered every to interfere with the uncompromised purity of their output. You will hear that familiar tracks sound noticeably sweeter and more involving as a result, or that the bass sounds fuller, cleaner and better controlled.

RE AL . COHERENT. IMMER SIVE . Single Apparent Source technology delivers sound from one point in space over the entire spectrum. Single source. Coherent sound. At the heart of Blade lies Single Blade is the world’s first Single Apparent Source technology. It is Apparent Source loudspeaker that an extension to the iconic Uni-Q extended the boundaries of what driver array, the building block of high-end audio can achieve. It is what makes the Blade incredibly Single Apparent Source technology coherent across the frequency aims to achieve the acoustic ideal range, with noticeably more precise...

Blade’s four powerful low frequency Nothing has been overlooked in the quest for clarity, right across the frequency range. drivers are mounted back-to-back to cancel out kinetic forces that might otherwise colour their output. By minimising cabinet coloration, this highly effective force-cancelling configuration partly accounts for the astonishing low-level resonance and the natural-sounding and In the latest Blade, the crossover engagingly musical performance. design has been enhanced to finetune the signal path for maximum clarity.
