Uncompromised Innovation

When KEF gave their engineers free rein to create the best speaker they could, they came up with the revolutionary Concept Blade prototype - the world's first single apparent source loudspeaker. Its sonic capabilities were so impressive that KEF created an edition that serious audiophiles could actually own: the Blade Two.

With all of Blade’s acoustic prowess and iconic design on a slightly smaller scale, Blade Two is easier to position where space is at a premium, and where Blade’s extreme bass extension would be superfluous. Blade Two, same DNA. Same striking aesthetic. Same advanced driver technology and unique single apparent source configuration. And above all, the same lush, phenomenally realistic sound.

Blade and Blade Two share a new architecture that achieves the ideal point source, with the four sophisticated bass drivers (225mm/9-in. for Blade, 165mm/6.5-in. for Blade Two) 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. Inside, you find ingenious new venting, bracing and wave management technologies. Every component operates so comfortably within its performance envelope that you experience noticeably more precise imaging than is possible with conventional speakers.


Kent Engineering and Foundry Editions

Asserting the sophistication of the technology they contain, the stunning Blade & Blade Two cabinets are available in a palette of seductive finishes: Piano Black, Snow White, Warm Metallic Grey, Light Metallic Silver, Racing Red, along with two specially commissioned ‘Kent Engineering and Foundry’ finishes, which celebrate KEF’s unrivalled heritage of continuous innovation for over 50 years.

Frosted Blue, hinting at the blue of the original KEF logo, and Frosted Copper Black - the Kent Engineering and Foundry editions combine the latest Blade technology with an aesthetic that subtly evokes this rich pedigree.
