Overview

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 (MAT™) driver array, this solid, compact loudspeaker is capable of delivering detailed sound anywhere in the room.

LS50 Meta

Every note. Every word. Every detail.

Great loudspeakers disappear, leaving just the music. LS50 Meta is such a loudspeaker. The incredibly immersive sound means 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.

Metamaterial Absorption Technology (MAT ™)

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.

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 coloration, 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. It’s 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 coloration 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.

Design

Attention to every detail

Every aspect of LS50 Meta has been considered for acoustic benefits and from a design perspective. The low-diffraction curved front baffle is subtly mirrored by the gently radiused rear panel, where both the port exit and speaker terminals have been elegantly recessed and softened visually.

Designed for performance

LS50 Meta may look sensational, but as a high-performance loudspeaker every aspect of its design is a case of form following function. From the precision modelled curved baffle to the solid, reinforced cabinet, every inch of LS50 Meta has been designed to perform.

Finished to perfection

LS50 Meta is much more than just a utilitarian loudspeaker; it is a piece of sculpture that livens up your life. This is why we offer a choice of four finishes, Carbon Black, Titanium Grey, Mineral White, and Royal Blue Special Edition.
