LS50 META

The World’s First Speakers with Metamaterial

LS50 Meta is a highly precise, emotionally engaging loudspeaker built on revolutionary acoustic technology. Designed around the Uni-Q 12th Generation with Metamaterial Absorption Technology driver array, this solid, compact loudspeaker is capable of delivering detailed sound anywhere in the room.

Metamaterial Absorption Technology

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

Created to eliminate 99%

Metamaterials are specially developed structures that use existing materials in such a way that they exhibit new properties. MAT’s tuned channels absorb 99% of the unwanted sound from the rear of driver, compared to around 60% absorption from loudspeakers using different approaches.

Always innovating

KEF always pushes the technological boundaries in its mission to create the best possible sound; MAT is the physical manifestation of that drive. The result of a joint development project with the Acoustic Metamaterials Group, MAT breaks completely new ground in loudspeaker design.

Every spot is the sweet spot

12th generation Uni-Q with MAT

Using advanced simulation and analysis tools, our 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.

Enhancement from legendary LS50 Lineage

Great loudspeakers disappear, leaving just the music. LS50 Meta is such a loudspeaker, and 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.

Curved for performance

LS50 Meta’s low-diffraction, curved baffle 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.

Braced for action

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.

Flexible port

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.
