Why you will love it
12th generation Uni-Q with MAT
KEF's Uni-Q puts the tweeter at the centre of the midrange/bass cone. KEF says this spreads sound evenly through the room, so the sweet spot is wherever you sit.
KEF calls the LS50 Meta the world's first speaker with Metamaterial Absorption Technology (MAT). It describes MAT as a maze-like structure that absorbs 99% of the unwanted sound from the rear of the tweeter.

Cabinet and port
The curved, low-diffraction baffle is modelled around the Uni-Q array. KEF makes the baffle from injection-moulded Dough Moulding Compound, with internal cross bracing and Constrained Layer Damping to reduce vibration.
The patented off-set flexible port was shaped with computational fluid dynamics. KEF says this delays turbulence and stops port walls colouring the midrange.
A family of colours
KEF lists six finishes on its Australian page: Carbon Black, Titanium Grey, Mineral White, Moss Green and Sand Shell, plus the Royal Blue Special Edition.
The speakers were designed by Simon Davies and the KEF Industrial Design Team, as a successor to the LS50.
