LS50 Wireless II has audiophiles covered with support for streaming music files up to 24bit/384kHz, as well as MQA, DSD256, and Roon Ready (coming soon). These features mean that even the experienced HiFi enthusiast will marvel at this exceptional loudspeaker’s ability.
All aspects of the LS50 Wireless II’s performance are aided by KEF’s bespoke Music Integrity Engine. This collection of bespoke Digital Signal Processing algorithms is optimised for the Uni-Q driver, enabling it to deliver a perfectly timed performance, for better imaging and a tighter sound.
The built-in amplifiers have been developed in-house by KEF. Each tweeter is driven by a 100W class A/B amplifier that delivers a smooth, incredibly detailed treble performance. Dedicated 280W class D amplifiers power the mid/bass drivers, for room-filling, controlled sound up to 108db.
The brand-new dedicated KEF Connect app controls LS50 Wireless II on a day-to-day basis, including intuitive sound settings so you can tune the sound to your own personal tastes. You can even select your favourite source to wake up LS50 Wireless II whenever it comes on, allowing you immediate access to the best sound.
