Evolution of an Icon
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.
Metamaterial Absorption Technology (MAT)
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.
12th Generation Uni-Q
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.
Patented Off-Set Flexible Port
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.
Meticulous Attention to Detail
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. Browse the S2 Floor Stands here.
Recognised For Excellence
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.
