Key Features
The KEF LS50 Meta Speakers and KEF S2 Speaker Stands (Pair) package offers the same signature LS50 series voice, but provides you with an ideal platform to enhance sonic performance. Keep your sound system neat, with integrated cable management and secure mounting system. These stands correspond with the dimensions of the LS50 Wireless II and also suitable for other KEF bookshelf speakers, meaning you can expand and experiment with your KEF home audio experience.
The LS50 Meta Speakers are the first to employ KEF's Metamaterial Absorption Technology, a maze-like structure which absorbs 99 per cent of unwanted sound (distortion). This innovation, combined with the 12th generation Uni-Q driver array, ensures exceptional acoustic accuracy with minimal colouration.
A patented offset flexible port, cleverly designed using computational fluid dynamics, contributes to reduced turbulence. The rear position of this port ensures the cabinet is robust and deadens internal vibrations with the help of additional bracing. Curved cabinet surfaces help minimise interferences even further. KEF offers the LS50 Metas in four silky matte finishes, any of which will make an elegant and modern addition to your home.

"For yet another year the KEF LS50 Meta speakers remain the class leader at this level"
“These standmounters set new standards at the price”
"...KEF is on to something with the Metamaterial technology and can’t wait to see how it develops. As things stand, that tech and all the other work KEF’s engineers have put into the Uni-Q array has propelled the LS50 Metas to the head of the class at this level. Buy them with confidence."
"The KEF is able to perform feats of soundstaging, time alignment and sheer impact that are an absolute delight."
In 2011, KEF introduced the iconic LS50, a loudspeaker born from a commitment to innovation and a relentless pursuit of audio excellence. Drawing inspiration from the classic LS3/5A, the LS50 quickly became a modern icon in their own right. Then, in 2020, KEF proudly presented the LS50 Meta, the natural evolution of its predecessor. Meticulously crafted with the latest technologies and design philosophies, the LS50 Meta stands as a testament to KEF's dedication to pushing the boundaries of audio reproduction.
A groundbreaking feature of the LS50 Meta is the implementation of Metamaterial Absorption Technology (MAT). Developed in collaboration with the Acoustic Metamaterials Group, MAT transforms the landscape of loudspeaker design. This complex maze-like structure efficiently absorbs specific frequencies, acting as an acoustic black hole and eliminating unwanted sound distortion. The result is a purer, more natural acoustic performance, showcasing the abilities of this cutting-edge technology.
At the heart of the LS50 Meta is the 12th generation Uni-Q with MAT driver array. This point source configuration delivers a detailed, accurate, and integrated 3D sound image, dispersed evenly throughout the room. Through meticulous simulation, analysis, and decades of expertise, KEF engineers have refined the driver array, reducing distortion and enhancing transparency. The LS50 Meta's bass performance surpasses expectations, delivering room-filling sound with deep, articulate bass.
The LS50 Meta's patented offset flexible port, designed with Computational Fluid Dynamics (CFD), plays a crucial role in achieving exceptional clarity. Calculated to delay turbulence onset, the port's flexible walls prevent midrange colouration, resulting in improved depth and detail. The speaker's extremely rigid cabinet, engineered from advanced materials, further minimises colouration, making the LS50 Meta a standout performer in its class.
Inheriting the distinctive aesthetics of the original LS50, the LS50 Meta boasts a low-diffraction, curved baffle precisely shaped around the Uni-Q driver array. The cabinet's smooth curved surfaces, injection-moulded Dough Moulding Compound (DMC) baffle, and meticulous internal bracing contribute to the lowest colouration in its class. Available in four modern matte finishes, the LS50 Meta exudes elegance, while the matching S2 Floor Stands enhance visual appeal and functionality.
The LS50 Meta has garnered accolades from What Hi-Fi?, earning titles such as 'Best standmount speaker' in its price category as well as a glowing five-star review. This premium speaker, with its remarkable functionality and unparalleled sound quality, stands as a testament to KEF's enduring commitment to delivering an immersive and believable audio experience. As the successor to a long-celebrated lineage, the LS50 Meta continues KEF's tradition of pushing the boundaries of audio innovation and setting new standards in the world of high-fidelity sound.
The KEF S2 Speaker Stands are made for the LS50 Meta, LS50 Wireless II, and other stand-mountable speakers from KEF. Their steel and aluminium construction helps couple your speakers for sturdy and stable elevation with minimised vibration.
Not only will the S2s elevate your speakers to the optimal listening height but they'll also hide your cables from view in an integrated cable management system. To top it all off, these stands are colour-matched to the exact finish of the KEF LS50 Meta speakers!
