KEF Blade One Meta

The world’s first Single Apparent Source speaker

The 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.

Uncompromised Innovation

Obsessed with sound quality and committed to bringing a superior listening experience, our engineers created the revolutionary Concept Blade to showcase KEF’s technology leadership and powers of innovation with no preconceptions and restrictions. Since then, we keep pushing the boundaries of HiFi to create the loudspeaker with the best possible sound.

Uniquely KEF. Uniquely coherent.

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™).

Engineered and handcrafted in UK

Since 1961, we have been creating remarkable award-winning loudspeakers at our UK home in Maidstone, Kent. As our flagship HiFi speakers, Blade is still being designed, engineered, and handcrafted in Maidstone.
