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.

Uncompromised Innovation

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™).

Uniquely KEF. Uniquely coherent

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.
