KEF LS50 Meta Speakers

The KEF LS50 Meta Bookshelf Speakers are the first speakers to use Metamaterial Absorption Technology to eliminate 99% of high-frequency distortion and resonance for an enhanced sonic performance from any music.

The LS50 Meta speakers are the first speakers engineered with Metamaterial, breaking new ground in speaker design. Jointly developed with Acoustic Metamaterials Group, the Metamaterial Absorption Technology (MAT) uses specially developed structures that create new properties from existing materials that are not found in naturally occurring substances. MAT features a highly complex maze structure, allowing each of the channels to absorb a specific frequency. With all the channels together, MAT creates an acoustic black hole, absorbing 99% of unwanted resonant frequencies, providing a purer, natural performance without distortion.

The LS50 Meta speakers use a Uni-Q tweeter, positioned in the centre of the main driver for optimum timing. The 12th generation Uni-Q driver delivers point source detailed and accurate sound, dispersed evenly throughout the room. Enjoy your music from any seat and always be in the sweet spot. The midrange driver features a new precisely shaped decoupler and motor system designed to reduce high-frequency distortion. This results in a sound that is more transparent and life-like than the previous LS50. The bass performance exceeds expectations from the compact speaker with deep, articulate bass.

The rear port design also contributes to the clarity of the performance, with Computational Fluid Dynamics offsetting the port to prevent midrange colouration. The design enhances the detail and depth on offer from the LS50 Meta. The curved front helps radiate sound across the baffle without interference for a smooth sound reproduction. The LS50 Meta cabinet is extremely rigid for the best performance, with cross bracing to prevent vibrations.

The LS50 Meta retain the same design of the LS50 speakers, with the low-diffraction baffle and centrally aligned Uni-Q driver. On the underneath of each speaker, a thread insert is fitted, allowing you to secure the LS50 Meta to the new KEF S2 stands, for the best performance from the speakers. The LS50 Meta speakers are available in four different finishes, all silk matte, with black, white, grey and royal blue options.
