KEF Blade Two Loudspeaker

“The KEF Blade Two preserves all the positive qualities that made KEF’s little LS50 Stereophile’s “Product of 2013,” while adding greater dynamic range and two more octaves of bass extension… that imaging magic and its midrange clarity make the Blade Two a winner all the way.

KEF’s Blade Two offers superb measured performance that is close to the state of the art.”
– John Atkinson, Stereophile (read the review)

“There are a handful of loudspeakers I’ve encountered at the countless audio demos and shows I’ve covered for Stereophile—models from, in alphabetical order, Dynaudio, Hansen, Magico, Revel, TAD, and Wilson come immediately to mind—that I would welcome hearing again, and be thrilled to enjoy in my own listening room. To this list I would add KEF’s Blade.”
– Jason Victor Serinus, Stereophile

“KEF’s amazing Blade is a statement speaker in so many ways: as an aesthetic object; as a culmination of knowledge and experience gained over 50 yrs; as a demonstration that advanced technology can solve certain problems that brute force and exotic materials cannot – AND proof that the predicted benefits are real; and as the fruition of 5 yrs. of work that has not only met but exceeded all of its design goals. The Blade is a speaker that delivers an inordinate quantity of sonic and musical delight – no matter what you are listening to!
– Alan Taffel, The Absolute Sound

“Their combination of fit, finish and achievable performance represent exactly the sort of products not just that this industry should be making but that it must make if it wants to survive. A stunning indication of what happens when serious investment meets solid engineering and nobody applies the brakes on ambition, the KEF Blades present one of the most enjoyable and downright uplifting hi-fi experiences I have had in quite a while.”

KEF Blade Two Loudspeaker – Uncompromised Innovation

When KEF gave thier 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. This was so well received – and scooped so many prestigious awards – that KEF has now developed a second model, The Blade Two Loudspeaker.

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.

The KEF Blade Two Loudspeaker shares features a new architecture that achieves the ideal point source, with the four sophisticated bass drivers (165mm/6.5-in.) 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.

Just as KEF’s philosophy has always been to innovate in pursuit of the most accurate and realistic sound, Blade speakers are about perfecting a groundbreaking concept to delight people who really love music. Whatever your taste, the Blade Two is what all great design aspires to: being the best it can possibly be.

Kent Engineering and Foundry Editions

Asserting the sophistication of the technology they contain, the stunning 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.

Or, given time, KEF will also match any color you want. Like everything else about the KEF Blade Two Loudspeaker, it’s about getting every last detail absolutely right.
