When it comes to physical technology, LS50 Wireless II takes its lead from KEF’s LS50 Meta passive loudspeakers. A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology1 (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 sound.
- Freedom: Plays all major music services and supports all major audio formats. Wireless both from source and between the speakers
- User Centered: Intuitive on-boarding with user-centered features and personalized listening experience via KEF Connect App
- Performance: Metamaterial Absorption Technology for pure, natural sound for exceptional acoustic accuracy. Music Integrity Engine for rich, full-bodied sound.
- Design: Optimized cabinet design for best acoustic performance. Available in 4 finishes with mounting inserts to secure on KEF S2 Floor Stand (available as separate item)

LSXII delivers room-filling, natural, accurate sound from any source thanks to the knowledge and experience of KEF's talented engineers and the iconic Uni-Q driver array.

For LS60 Wireless KEF’s engineers have seamlessly combined elements of the iconic Blade’s Single Apparent Source technology, a specially designed 12th Generation Uni-Q driver array, the revolutionary Metamaterial Absorption Technology , Uni-Core bass drivers and much more besides.

The LS50 Meta has inherited its distinctive good looks from the original LS50, with its low-diffraction, curved baffle precision modelled around the Uni-Q driver array. The curved front is subtly mirrored by the gently radiused rear panel, while both the port exit and speaker terminals have been elegantly recessed and softened visually. The LS50 Meta’s extremely rigid cabinet is optimised for performance, with smooth curved surfaces that help radiate sound out across the baffle without any interference
