LS50 MK2 Wireless Speakers

At the heart of the LS50 Wireless MKII is a new wireless platform, giving you access to all your favourite music through Spotify, TIDAL, Amazon Music and more, all with fantastic sound quality.

The LS50 Wireless MK2 speakers take their speaker technology from the LS50 Meta, the first speakers engineered with Metamaterial, breaking new ground in speaker design. Jointly developed with Acoustic Metamaterials Group, the Metamaterial Absorption Technology (MAT) features a highly complex maze structure, creating an acoustic black hole, absorbing 99% of unwanted resonant frequencies, providing a purer, natural performance without distortion.

The LS50 Wireless MK2 speakers use a Uni-Q tweeter, positioned in the centre of the main driver for optimum timing. The 12th generation Uni-Q driver delivers point source detailed and accurate sound, dispersed evenly throughout the room. Enjoy your music from any seat and always be in the sweet spot.
