“KEF has taken an excellent speaker and made it even better with its innovative Metamaterial tech. The LS50 Meta are now the class leader at this level.”

A Class Leader

Great loudspeakers disappear, leaving just the music. LS50 Meta is such a loudspeaker. The incredibly immersive sound means you lose yourself in your favourite music. Savouring every nuance as layer upon layer of instrumentation is delivered with exceptional acoustic accuracy anywhere in the room.

Every spot is the sweet spot

Using advanced simulation and analysis tools, our engineers have developed the 12th generation Uni-Q with MAT™. This new driver array delivers reduced colouration, less distortion and a sound that is more transparent and life-like than previously possible, all dispersed evenly throughout the room.

Attention to every detail

Every aspect of LS50 Meta has been considered for acoustic benefits and from a design perspective. The low-diffraction curved front baffle is subtly mirrored by the gently radiused rear panel, where both the port exit and speaker terminals have been elegantly recessed and softened visually.
