The World's First Speakers with Metamaterial

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.

Both LS50 Meta and LS50 Wireless II feature a 12th Generation Uni-Q driver array featuring an industry first - Metamaterial Absorption Technology (MAT). This particular Uni-Q driver, whilst being inspired by that of the R Series, has been engineered with regards to the overall system design. Firstly, the addition of MAT has necessitated considerable redesign of the driver structure, allowing KEF engineers to further refine technologies such as the tweeter gap damper. Secondly, where R Series features 3-way designs, LS50 Meta is a 2-way loudspeaker, meaning the midrange driver must cover a much wider bandwidth, down into bass frequencies. Whilst excellent for integration, this does provide challenges in regards to performance. With this in mind, KEF engineers made a number of changes to the motor system, suspension, surround and cone of the midrange driver to deliver as smooth a performance as possible.
