KEF LS50 Wireless II features new meta material, KEF Connect app platform and HDMI for better sound from your movies and gaming experience.

KEF LS50 Wireless II is more than a high-performance loudspeaker; it’s the perfect all-in-one speaker system, streaming from any source thanks to wireless compatibility with AirPlay 2, Chromecast and more, plus wired connections for your TV, games console and turntable.

This fully active wireless speaker delivers signature KEF sound coupled with great usability and wireless functionality. Based on the LS50 Meta speakers, the new wireless platform has been engineered from scratch. It sets a new benchmark of class-leading acoustics thanks to its active electronics, DSP, wireless streaming platform and new KEF Connect app.

LS50 Wireless II vs LS50 Wireless

KEF LS50 Wireless II features new meta material that absorbs 99% of rearward driver sound while the original LS50 Wireless absorbed 60% using vented tweeters. The result is a 40% smoother frequency response, extremely low distortion of 0.07% (compared to 0.1% on the original) and increased SPL from 106dB to 108dB.

Like the original, KEF LS50 Wireless II has direct access to Spotify and Tidal but also adds support for Airplay 2, Roon Ready, Apple Music, Amazon Music, Qobuz, Internet Radio, Chromecast and Bluetooth. The eARC HDMI input enables use with a screen to compliment video streaming services such as Netflix, Amazon Prime or for gaming.

It also no longer requires a cable between speakers and now supports a max res of 384kHz/32bit (MQA, DSD256). Built in amplifier power has been increased from 460W to 760W. Multiroom streaming is now possible as the speaker uses KEF's brand new app platform. It is available in carbon black, mineral white or titanium grey matte finishes as well as a special edition crimson red high gloss finish.

Playback Freedom

The new wireless platform of the LS50 Wireless II ensures minimal fuss and fantastic sound quality no matter how you like to listen to your music. Tune in to Internet Radio Stations and catch up on latest podcasts through the KEF Connect app.

Wired connections are included for TV, turntable, CD player and games console via the HDMI, analogue and digital inputs LS50 Wireless II streams audio files up to 24bit/384kHz as well as MAQ, DSD256 and is Roon Ready; Discerning hifi enthusiasts will marvel at this exceptional ability.

User-Centred Design

Beyond a flawless performance, LS50 Wireless II is easy to set up and use and offers OTA firmware updates bringing you new and improved features with minimum fuss. Connect the speakers with the supplied cable (24bit/192kHz res) or wirelessly (with 24bit/96kHz res) for a clutter-free set up.

You can even select your favourite source to wake up LS50 Wireless II whenever it comes on. Stream to multiple speakers using AirPlay 2, Chromecast or Roon and enjoy music throughout your home. The KEF Connect app walks you through set-up and controls the system with intuitive sound settings to tune LS50W 2 to your own personal tastes.

Accurate and immersive sound

LS50 Wireless II draws on the LS50 Meta speaker employing Metamaterial Absorption Technology (MAT); a maze-like structure where each channel efficiently absorbs a specific frequency. When combined, the channels act as an acoustic black hole absorbing 99% of the unwanted sound from the rear of the tweeter and eliminating the resulting distortion for a purer, more natural sound.

KEF's Uni-Q point source configuration evenly disperses a 3D sound image so the "sweet spot" is wherever you are in the room. The 12th gen Uni-Q with MAT driver reduces distortion in the midrange for reduced coloration and distortion. Sound is more transparent and lifelike with crystal clear midrange and deep articulate bass.

High-Performance Class A/B Amp

KEF’s bespoke Music Integrity Engine is a cutting-edge collection of bespoke DSP algorithms optimized for the new Uni-Q with MAT driver array to deliver perfectly timed performance with a tighter, unsmeared sound. Each tweeter is driven by a 100W class A/B amplifier producing smooth and incredibly detailed treble performance.

Dedicated 280W class D amplifiers power the mid/bass drivers for controlled room-filling sound. The amplifier is developed in-house by KEF so it completely controls the quality of power resulting in sensationally dynamic sound.

Elegant and striking design

LS50 Wireless II fit comfortably into your living space. The curved baffle is modelled around the Uni-Q driver array, heat sinks and colour-matched ports are set on the rear. LS50 Wireless II is available in three matt finishes, Carbon Black, Titanium Grey, Mineral White and a Crimson Red Special Edition.

On the LS50 Wireless II’s underside, each corner has a threaded inset allowing the speaker to lock onto the top of the new KEF S2 Floorstands. For even more impact and bass extension, LS50 Wireless II features two subwoofer outputs, one on each speaker.
