LS50 Meta

Every note. Every word. Every detail.

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.

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. Add a capable amplifier, and savour every nuance as layer upon layer of instrumentation is delivered with exceptional acoustic accuracy throughout your space.

12th generation Uni-Q with MAT driver array for exceptional acoustic accuracy
Driver Performance Optimisation for enhanced sonic performance, less distortion and reduced coloration
Patented off-set flexible port for reduced midrange coloration with exceptional levels of depth and detail
Optimised cabinet design for best acoustic performance
Available in 4 finishes
Mounting inserts to secure on KEF S2 Floor Stands (sold separately)

A Historic Speaker

Since 1961, KEF‘s mission has been to preserve the integrity of original sound with as little intervention as possible. The goal of every KEF product is to do one thing: provide you with a revealing listening experience that is as true to the original recording as is possible within the confines of your room.

The iconic LS50 was the physical embodiment of this singular approach. A loudspeaker that took its cues from the classic LS3/5A but was quickly recognised as a modern icon in its own right. The LS50 was born out of KEF’s willingness to think outside the box, to constantly search for new materials, techniques and technologies such as the use of computer aided design and continuous enhancement of the KEF’s signature Uni-Q driver array.

That was 2011, and time and technology have moved on. Since then our engineers have been upholding KEF’s driving philosophy and searching out new technological breakthroughs. The result is an icon in waiting : the KEF LS50 Meta Standmount Speakers. Instantly recognisable as the successor of the LS50, the LS50 Meta is born of the same KEF desire for continual development and is therefore fittingly the first loudspeaker to employ Metamaterial Absorption Technology.

Revolutionary sound absorption with Metamaterial Absorption Technology

A result of joint development with the Acoustic Metamaterials Group, using Metamaterial Absorption Technology (MAT) breaks completely new ground in loudspeaker design, and once again demonstrates KEF’s unrelenting passion for developing new technologies to improve your listening experience. Metamaterials are specially developed structures that use existing materials in such a way that they exhibit new, desirable properties that are simply not found in naturally occurring substances.

A truly revolutionary tool in the KEF acoustic armoury, MAT is a highly complex maze-like structure, where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural acoustic performance.

12th Generation Uni-Q with MAT

The tweeter in question sits at the heart of our 12th generation Uni-Q with MAT driver array. The Uni-Q point source configuration delivers a more detailed, accurate and integrated three-dimensional sound image, which is dispersed so evenly throughout the room that the ‘sweet spot’ is wherever you are in the room.

Using simulation and analysis tools and decades of accumulated in-house knowledge, our engineers have developed a new iteration of KEF’s signature driver array, with a new cone neck decoupler and motor system that is precisely shaped to reduce high-frequency distortion in the mid-frequency driver.

The result is reduced coloration, less distortion and a sound that is more transparent and life-like than previously possible. The same can also be said of bass performance, where LS50 Meta completely exceeds the expectations of a modestly proportioned standmount speaker to deliver room-filling sound with deep, articulate bass.

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 Details

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.

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. On the LS50 Meta’s underside, each corner has a threaded inset allowing the speaker to lock onto the top of the new KEF S2 Floor Stand, which also boasts integrated cable management and a mass-loadable column.

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 a Royal Blue Special Edition exclusive to LS50 Meta.
