The cutting edge of loudspeaker design
-When we gave our engineers free rein to create a fitting showcase for our technology leadership, they developed a revolutionary prototype that looked and performed like no other: Concept Blade, the world's first single apparent source loudspeaker.Its phenomenal sonic capabilities met with such praise that we decided to produce an edition that serious audiophiles could actually own. After two years of painstaking refinement - and in time to mark 50 years of KEF innovation - Blade is the result. Conceived from the outset to extend the boundaries of high end audio, it’s a unique synthesis of innovative engineering and groundbreaking design based on a new architecture that achieves the ideal point source to which all speakers aspire. This is because the four sophisticated new bass drivers are configured so that their combined acoustic centre occupies exactly the same point in space as that of the Uni-Q HF/MF array, so the sound appears to emanate from a single, flawlessly coherent source.Sculptural and acoustically inert, the slender parabolic enclosures are engineered never to interfere with the purity of the output. The advanced new hybrid cones are so light and rigid that their natural break-up point is never reached within the required frequency range. Inside, you find ingenious new venting, bracing and wave management technologies. Meticulously specified, super-premium components - every one operating so comfortably within its performance envelope that you experience noticeably more precise imaging than is possible with conventional speakers. What you hear sounds as if it’s live - emotionally engaging, richly musical and effortlessly natural. A revelation, pure and simple.
The Cutting Edge of Loudspeaker Design
When we gave our engineers free rein to create a fitting showcase for our technology leadership, they developed a revolutionary prototype that looked and performed like no other: Concept Blade, the world's first single apparent source loudspeaker.
Single Apparent Source
Like listening to one voice rather than many, sound from a single source is inherently clearer. Not only are the acoustic centers of the HF and MF drivers in the Blade’s Uni-Q array coincident, but the four LF drivers are mounted symmetrically equidistant from it so that their acoustic centers occupy exactly the same point in space.
Force Cancelling
To avoid dissipating the energy of such potent bass drivers in exciting the cabinet (and thereby generating resonance, especially at high volume), the large kinetic forces involved are cancelled out by mounting the LF drivers rigidly together, back-to-back. By minimizing cabinet coloration, this highly effective configuration partly accounts for the Blade’s natural-sounding and engagingly musical performance.
Discrete Bass Chambers
The twinned pairs of bass drivers are mounted in discrete chambers separated by an internal partition. By increasing the frequency of any internal standing waves to way beyond the crossover point, this reduces the need for damping material (which can otherwise impair bass quality). Nothing has been overlooked in the quest for the ultimate clarity, right across the frequency range.
Attention to detail
With a speaker as ambitious as the Blade, short cuts are out of the question. Everything has to be as right as it can possibly be.
 Terminals & terminal links
Two pairs of the finest audiophile quality WBT connectors allow bi-wiring to optimize the retrieval of low level detail in the music.
Low order crossovers
The simple low order crossovers specified for the Blade employ the best components available, carefully selected by a rigorous auditioning process so that every part of the signal path is fine-tuned for maximum clarity.
Hard wiring
The patented screw-in linking plugs are to full audiophile specification (as well as simplifying set-up by eliminating fiddly wiring links). All the crossover components are individually wired by hand rather than mounted on a conventional printed circuit board. As well as being more environment-friendly, this optimizes both reliability and sound quality by assuring the cleanest possible signal transmission.
