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.
Ls50 meta vs ls50 driver#
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.
