The KEF LS50 Meta Speakers are the first to employ KEFs Metamaterial Absorption Technology a maze-like structure at the rear of the driver which absorbs 99 per cent of unwanted sound (distortion). This innovation combined with the 12th generation Uni-Q driver array ensures exceptional acoustic accuracy with minimal colouration. A patented offset flexible port cleverly designed using computational fluid dynamics contributes to reduced turbulence. The rear position of this port ensures the cabinet is robust & deadens internal vibrations with the help of additional bracing. Curved cabinet surfaces help minimise interferences even further. KEF offers the LS50 Metas in four silky matte finishes any of which will make an elegant & modern addition to your home.
