Enter Another Dimension: KEF R8 Meta Dolby Atmos Surround Speakers Can Be Wall-Mounted or Placed Atop Other R Series Models, Feature MAT Technology

Able to be wall-mounted or placed on top a pair of an R Meta Series loudspeakers, the KEF R8 Meta Dolby Atmos Flexible surround speakers help bring cutting-edge cinematic experiences to the home environment. A smart and easy way to get immersive Dolby Atmos sound, they bounce sound off the ceiling when placed atop another R Meta model — all without requiring custom installation. The presence of a 12th-generation Uni-Q driver array with Metamaterial Absorption Technology that eliminates 99% of unwanted noise from the rear of the driver gives the 9.9-pound R8 Meta the advantage over most Atmos speakers — and the ability to convey results that are positively three-dimensional. 

MAT: Breakthrough Sound Absorption
Metamaterial Absorption Technology (MAT), a revolutionary innovation that takes the performance of the 12th generation Uni-Q driver array to another level in terms of accuracy and clarity, is a hallmark of the R Meta Series. MAT is a highly complex maze-like structure, where each of the intricate channels efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of the unwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providing a purer, more natural acoustic performance.
