LS50 Meta

Released in late 2020, the KEF LS50 Meta loudspeakers are the next step for their award-winning LS50 design. These compact, powerful cabinets can lay claim to being the world’s first speakers using metamaterial.

A new revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT) is a highly complex maze-like structure that absorbs 99% of unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.

LS50 Meta delivers incredibly immersive sound, meaning you lose yourself in your favourite music. Savouring every nuance as layer-upon-layer of instrumentation is delivered with exceptional acoustic accuracy, anywhere in the room.

Using advanced simulation and analysis tools, KEF engineers have developed the 12th generation Uni-Q with MAT. This new driver array delivers reduced colouration, less distortion and a sound that is more transparent and life-like than previously possible, all dispersed evenly throughout the room.

Enhancements over the legendary LS50 include Driver Performance Optimisation and patented off-set flexible port for the best acoustic performance and an incredible immersive sound.

The KEF LS50 Meta has a low-diffraction, curved baffle which is precision modelled around the Uni-Q driver array. Its smooth curved surfaces help radiate sound out across the baffle without any interference from hard edges, which cause diffraction. The result is cleaner, more precise sound.

LS50 Meta’s baffle is engineered from an injection-moulded Dough Moulding Compound (DMC), while inside the cabinet cross bracing and Constrained Layer Damping (CLD) combine to deaden internal vibrations. The result of such meticulous attention to detail is the lowest colouration of any speaker in its class.

Using Computational Fluid Dynamics (CFD), the port flare and profile of LS50 Meta’s patented off-set port is calculated to delay the onset of turbulence, and the flexible port walls prevent resonances from colouring the midrange. This leads to improved clarity, with exceptional depth and detail.

LS50 Meta is a piece of sculpture that livens up your room and your life. Available in a choice of four finishes, Carbon Black, Titanium Grey, Mineral White, and Royal Blue Special Edition.

LS50 Meta is a winner in the What Hi-Fi? Awards 2020.

Founded in 1961 by ex-BBC electrical engineer Raymond Cooke OBE, KEF was initially headquartered in a Nissen Hut on the premises of Kent Engineering & Foundry (from where the name KEF is derived), a metal-working company on the banks of the River Medway, near Maidstone in Kent.

From the very beginning, the pioneering inventiveness of KEF loudspeakers was undeniable and now for several decades, audiophiles around the world have revered KEF for their innovative, high-performance, beautiful loudspeakers.
