Uniquely KEF. Uniquely coherent.

At the heart of Blade lies Single Apparent Source technology; a unique technology that aims to achieve the acoustic ideal of a point source, where low, mid and high frequencies radiate from one point. It is what makes the Blade incredibly coherent, with noticeably more precise imaging.

So pure. So KEF.

The latest version of Blade benefits from our latest acoustic innovation: Metamaterial Absorption Technology (MAT™).  MAT™ is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.

Sit anywhere, hear every detail

Refined through iterations, the Uni-Q®driver array for the latest Blade is the 12th generation Uni-Q®with MAT™. Uni-Q®acts as a single point source to disperse sound more evenly throughout the room. The result is the elimination of the limited ‘sweet spot’, therefore allowing everybody sitting at different spots in the room to experience and enjoy the same natural, detailed sound.

Performance by design

With the philosophy of innovating in pursuit of the most accurate and realistic sound, Blade is about perfecting a groundbreaking concept to delight people with the ultimate listening experience.

Power in control

Blade’s four powerful low frequency drivers are mounted back-to-back to cancel out kinetic forces that might otherwise colour their output. The result is cleaner, purer sound, and astonishing low-level resonance

Cutting edge sound

Blade’s four powerful vented bass drivers are perfectly integrated with the 12th generation Uni-Q®with MAT™ to deliver clean, immaculately controlled bass. The crossover design in the latest Blade has been enhanced to fine-tune the signal path for maximum clarity.

Discrete chambers for pure sound

On Blade, each pair of low frequency drivers is located in its own chamber. This approach reduces the potential for interference between the drive units, while also reducing the need for damping, which can impair bass quality
