Since 1961, KEF have been creating remarkable award-winning loudspeakers at thier UK home in Maidstone, Kent. Blade is still being designed, engineered, and handcrafted in Maidstone. The Blade, world's first Single Apparent Source speaker, now with 12th generation Uni-Q^® with MAT™. A bespoke driver array engineered to deliver pristine performance, and capable of raising Blade to new heights of performance. Featuring four 225mm (9 in.) force-cancelling bass drivers, Blade One Meta is the top model in the Blade series

A Sound Statement

A bold and striking presence, Blade pushes the boundaries of what is possible with sound. The world’s first Single Apparent Source loudspeaker now with KEF’s innovative Metamaterial Absorption Technology

The World’s First

At the heart of Blade lies Single Apparent Source technology; a unique technology that makes the Blade incredibly coherent, with noticeably more precise imaging. The latest version of Blade benefits from our latest acoustic innovation of the 12th generation Uni-Q^® with Metamaterial Absorption Technology (MAT™).

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.

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.
