BLADE TWO


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.

 

FEATURES

 

Uncompromised Innovation

Like the original BLADE, BLADE TWO is based on the advanced materials and innovative technologies KEF developed to replicate the shattering performance of the prototype, and the same method of forming the sensuous parabolic cabinets. The drivers on both models share the sophisticated enhancements responsible for the concept’s magical acoustics.

It’s a spectacularly warm and expansive sound, wherever you sit. Seamless. Totally natural, even when played loud. Effortlessly accurate in every tiny detail, and as emotionally true as a live performance.

If you’re into your music, you’ll soon see that they years it took to make the dream a reality were well worth it.

 

BLADE & 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.

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, BLADE and BLADE TWO are what all great design aspires to: being the best they can possibly be.

 

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.

Given time, we’ll also match any colour you want. Like everything else about BLADE and BLADE TWO, it’s about getting every last detail absolutely right.

Technology

 

Single apparent source

Like listening to one voice rather than many, sound from a single source is inherently clearer. Not only are the acoustic centres of the HF and MF drivers in the Blade & Blade Two Uni-Q array coincident, but the four LF drivers, (225mm/9-in. for Blade, or 165mm/6.5-in. for Blade Two) are mounted symmetrically equidistant from it so that their acoustic centres occupy exactly the same point in space.

This single apparent source configuration is what makes the Blade & Blade Two so gratifyingly coherent across the frequency range, with noticeably more precise imaging than is possible from any conventional speaker.

What you hear sounds as if it’s being performed live right in front of you.

 

 

Design and Designer

The challenge was to design an acoustically efficient enclosure for a sizeable speaker whose driver configuration demanded large capacity at the upper portion, without looking at all bulky.
 
Initially, our team worked alongside Eric Chan of New York-based ECCO Design to create a distinctive visual identity for a speaker of such towering performance capabilities. As functional as they are beautiful, the resulting cabinets are like works of art in their own right – indeed, their form was inspired by Brancusi’s seminal Modernist masterpiece ‘Bird in Space’. Tapering gracefully from top to bottom and from front to rear, the slim proportions made possible by the orientation of the bass drivers give the Blade & Blade Two a sculptural presence in their own right, with a single continuous keyline describing a taut, seamless curve along the back edge and over the top.
