But some sound energy always bounces off the dome, causing distortion. In conventional designs, this sound usually flows into the chamber behind the dome, where it is mostly absorbed by the damping material. With MAT, the speaker successfully copes with sound coming from the rear of the 25 mm aluminium tweeter dome. MAT-Metamaterial Absorption Technology is used to create a labyrinthine system, resulting in a cleaner, more natural, distortion-free sound. The thick MDF sheets, courtesy of CFD (Computational Fluid Dynamics) technology, delay turbulence and keep the midrange cleaner. The baffle is made of DMC compound, which, together with internal reinforcements, reduces internal vibration. The holes for the front baffle mounting screws have disappeared, giving the speaker a neater, tidier look. The only obvious change from previous models is the rear panel. The modern, clean look is easy to integrate into almost any style of room. The LS50 Metas are available in four colours – white, jet black, titanium grey and Royal Blue Special Edition.Ī thick, rigid speaker cabinet ensures the right stability. The rest of the two-way bass-reflex speaker cabinet is made from MDF, which is heavily braced and carefully damped to minimise resonances. The KEF LS50 Meta is the world’s first Uni-Q loudspeaker to use “Metamaterial” technology. Dimensions (height) 30.2 x 20 x 27.8 cm.Some important features of the KEF LS50 Meta: The shape and size of the cabinet is optimal and the curved front panel is made of polyester combined with fibreglass and calcium carbonate – creating an impressively rigid and well-controlled base for the Uni-Q technology, the company’s own innovation. The Meta has a matt casing, which is also an advantage because it prevents fingerprints and dust from showing. The LS50 Metas are not dissimilar to the original LS50, yet they are not exactly the same in many ways. The company’s engineers did not sit back, however, and the result is the fresh-looking LS50 Meta Speakers. These floor-standing speakers were a huge success, so much that they have continued to produce them unchanged ever since in large quantities. To celebrate its anniversary, KEF launched the original LS50 loudspeakers in 2012. ![]() The company was founded by Raymond Cooke. The KEF brand name is short for “Kent Engineering and Foundry”. The British KEF brand has been in the audio and hi-fi business since 1961. ![]() The LS50 Meta – especially when you consider its price – ticks every box for a small speaker: huge soundstage, generous bass, terrific imaging.We tested the KEF LS50 Meta bookshelf speakers and liked it! "Shocking is not a word to bandy about lightly but the gains over the original LS50 are so obvious, so immediately perceived that one can only shake one's head in disbelief that this was achieved, in part, by a passive internal tweak. " It presents a more transparent window into the recorded soundstage without compromising the ability to communicate the music's message. ![]() As with previous LS50 models, the cabinet use a grille-less design to show off the cool-looking driver array. It also features a patented offset, flexible port for reduced midrange coloration. The LS50 Meta's extremely rigid cabinet uses smooth, curved surfaces that help the sound radiate outward without distortion. The resulting sound is clear, purer, and more detailed It's a highly complex, mazelike structure that's tuned to absorb unwanted sound coming from the rear of the tweeter. This speaker gets the "Meta" part of its name from KEF's new and innovative Metamaterial Absorption Technology (MAT). With both acting as a single point source, the sound is dispersed widely and evenly throughout the listening area allowing you to experience superbly defined and perfectly balanced stereo imagery with a wide "sweet spot" Revolutionary sound absorption The LS50 Meta bookshelf loudspeaker utilizes KEF's patented 12th Generation Uni-Q driver configuration, in which the tweeter is mounted at the acoustic center of the midrange cone. ![]() Note finishes other than Black are available - please call KEF LS50 Meta Speakers 12th Generation Uni-Q Driver Array
