KEF META DRIVER
KEF META SERIES

Even Maria Pihl's listening test standard 'Malvina', a title that misses its effect when performed weakly, retained a solid foundation via the new LS50, above which the spectrum of brooding synthesizer swathes piled up, while the singer stood realistically outlined and as if fixated right between the speakers.Īs a result, the little KEF speakers really did play as holistically and coherently as the Uni-Q promises. It was less the fullness than the precise punch that created the effect of increased conciseness in the lower registers.Ībove that, the middle and high frequencies connect seamlessly. This is where its predecessor already surprised with and which the new one even slightly improves upon. In our listening test, the Meta-LS50 didn't cause any problems, but played – once set up correctly – just as committed and clear as well as surprisingly profound, in view of its compact dimensions. Together with the new Meta speakers, a matching 'S2' stand is available in the respective color, on which the little box, weighing approximately eight kilograms, can be fixed fall-proof. In view of this innovation, it is almost pointless to mention that the LS50 Meta naturally retains its traditional qualities: the multi-layered, double-stiffened housing and the easy-grip clamps in the single-wire terminal as a few examples. Its designers calculated specific channels for different frequencies and their wavelengths, the combination of which is intended to achieve maximum absorption in the smallest possible space because the sounds in them die out or can no longer return by reflection. The synthetic material is the result of a joint development initiative with specialists from the 'Acoustic Metamaterials Group' in Hong Kong, who are known for their scientific expertise.Īnother important aspect in this context is the maze-like surface structure of the damping disc. Similar to a plug, a round, cleverly designed cover closes the rear outlet opening of the Uni-Q and is supposed to absorb 99 percent of its energy like a 'black hole for sound' and in this way reduce distortions and overlapping – according to Oclee-Brown, other solutions would have achieved a maximum of 60 percent. But hardly anyone does this as effectively as KEF.Īt the heart of this is the 'Metamaterial Absorption Technology', or 'MAT' for short. This is why a number of manufacturers found individual solutions to divert these sounds and make them harmless. However, these components can lead to discoloration, as they get out through the rear bass reflex port, for example. To avoid congestion and reflections, its dome exhales freely through a sound guide to the rear. This became necessary because the drive of the tweeter is significantly more powerful.

Compared to the driver previously used in the LS50, there is a damping element in the sound guiding that reduces unwanted vibrations, for example.

He used the twelfth-generation Uni-Q, which has already been optimized in many respects and is used in the ambitious R series from the British manufacturer, as a basis. He has tested and analyzed the successful model 'on its meta-level' both in theory and in the laboratory very carefully and then improved it in many ways.

Most of it might be credited to KEF's young and immensely knowledgeable head of development Dr. Now, however, the LS50 Meta evolved out of the elder specimen in a completely new form – at least as far as the sophisticated technology is concerned.

The loudspeaker seemed thus infinitely versatile.
