KEF LS50 Wireless II Speakers


The KEF LS50 Wireless II is more than just 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. Great sound, no strings attached.

Speaker stands provide the perfect platform for your speakers to perform. These matching KEF S2 floor stands are made to measure.

The LS50 Wireless is great on its own, but you can take it even further by adding a subwoofer or, better yet, a pair of subwoofers. The KEF KC62 subwoofer is an ideal match.

Every aspect of the KEF LS50 Wireless II has been considered for acoustic benefits and from a design perspective. The low-diffraction, curved baffle is precision modelled around the Uni-Q driver, while eye-catching heat sinks and colour-matched ports are located on the well-equipped rear. The top-mounted control panel is designed to be stylish and functional.

Really great loudspeakers simply melt away, leaving you with just the music. A pristine voice, perfectly rendered layers of instruments you can lose yourself in, sound so clear it’s as though the artist is there with you. This is what great loudspeakers with the best technology deliver.

The perfect colour for you

The KEF LS50 Wireless II is available in three matte finishes, carbon black, titanium grey, and mineral white, as well as a crimson red special edition. All the colour options are mirrored on both the drive units and the rear-facing port. The top-mounted control panel is designed to be stylish and functional.

Even beyond the flawless musical performance, LS50 Wireless II is a breeze to set up thanks to the KEF Connect app. It is intuitive to use with any source in your home, and it allows simple over-the-air firmware updates that bring you new and improved features with the minimum of fuss.

You can choose to operate KEF LS50 Wireless II completely wirelessly at 24bit/96kHz resolution for a completely clutter-free set up, or you can connect the two speakers with the supplied cable for 24bit/192kHz resolution sound.

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.

Simple multiroom system

When using LS50 Wireless II with Airplay 2, Chromecast or Roon you can stream to multiple speakers around your home at the same time. By using multiple LS50 Wireless II speakers, you can have a simple, high-performance multiroom system.

Metamaterial Absorption Technology

A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology ( MAT™) is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound.

Music Integrity Engine

All aspects of the LS50 Wireless II’s performance is 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.

Plentiful power

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.

What’s new

Owners of the original KEF LS50 Wireless may be wondering what’s new? The answer is pretty much everything. The original was fantastic, but LS50 Wireless II is better in every respect, with improved sound, better connectivity and usability thanks to the brand new W2 wireless platform.
