In 2009, KEF gave its engineers free rein to create a speaker showcasing the company’s innovation. The result was the Concept Blade – the world’s first Single Apparent Source loudspeaker. By 2011, Blade became a high-fidelity speaker for audiophiles. Since then, KEF continues to push the boundaries of HiFi to create loudspeakers with the best possible sound.

At the heart of Blade lies KEF's Single Apparent Source technology, a unique innovation that makes the Blade incredibly coherent, with noticeably more precise imaging. The Blade Meta models now feature KEF’s latest 12th-generation Uni-Q® driver with Metamaterial Absorption Technology (MAT™), showcasing their most advanced acoustic innovation.

Since 1961, KEF has been creating remarkable award-winning loudspeakers at their UK home in Maidstone, Kent. As KEF's flagship HiFi speakers, Blade is still being designed, engineered, and handcrafted in Maidstone.

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.

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.

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.

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.
