Audio performance
- Wide soundstage
- Great clarity and detail
- Well-controlled bass
We're happy to report that the LS50 Wireless II stereo speakers continue to provide the phenomenal audio quality offered by their predecessors – and then some.
Audiophiles will be pleased with support for streaming files up to 24-bit/384kHz, as well as MQA and DSD256; but even if you eschew the wonders of Hi-Res Audio in favor of some simple Spotify streaming, you won't be disappointed by the sound.
The LS50 Wireless II sound incredibly well balanced, displaying great stereo separation and a wide enough soundstage to truly fill any room with detailed, clarified audio.
Part of that sonic prowess is down to the use of Uni-Q speakers, which KEF says allows for “three-dimensional, wonderful revealing sound” – and we agree. Each tweeter is powered by a 100W class A/B amplifier, designed to deliver a “smooth, incredibly detailed treble performance”, while the mid and bass drivers are driven by dedicated 280W class D amplifiers for a powerful sound.

We heard that audio power in action when we listened to Tears For Fears' Everybody Wants To Rule The World. Jangly guitar riffs sounded crisp and clear, while the pulsing bass was forceful without overpowering the other frequencies.
We were also impressed by their great sense of timing and dexterity, with the speakers deftly handling the driving rhythm of the track and Roland Orzabal's distinctive, reverb-heavy vocal.
This rhythmic agility is made possible by KEF's Music Integrity Engine. This uses digital signal processing (DSP) algorithms that have been optimized for the speakers' Uni-Q drivers, which KEF says helps the LS50 Wireless II to deliver “a perfectly timed performance, for better imaging and tighter sound”.
