The LS50 Meta is a highly precise, emotionally engaging loudspeaker built on revolutionary acoustic technology. Designed around the Uni-Q 12th Generation with Metamaterial Absorption Technology driver array, this solid, compact loudspeaker is capable of delivering detailed sound anywhere in the room.

Great loudspeakers disappear, leaving just the music. LS50 Meta is such a loudspeaker, and enhancements over the legendary LS50 include Driver Performance Optimisation and patented off-set flexible port for the best acoustic performance and an incredible immersive sound.

Design

Attention to every detail

• Optimised cabinet design for best acoustic performance
  
• Available in 4 finishes
  
• Driver Performance Optimisation for enhanced sonic performance, less distortion and reduced coloration
  
• With mounting inserts to secure on KEF S2 Floor Stand (available as separate item)

The LS50 Meta's low-diffraction, curved baffle is precision modelled around the Uni-Q driver array. Its smooth curved surfaces help radiate sound out across the baffle without any interference from hard edges, which cause diffraction. The result is cleaner, more precise sound.

A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology (MAT™) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.
