KEF has announced its follow up to the successful LS50 Wireless speakers. KEF's LSX is a more compact, more affordable fully wireless stereo music system.

StereoNET UK was at the unveiling of the KEF LSX compact two-speaker wireless music system at the Soho Hotel in central London.

Even though the situation was far from perfect, the LSX both looked and sounded impressive. How impressive? Check out the review over on StereoNET AU.

KEF LSX details

KEF LSX Colors

Building on the success of the LS50 Wireless, the LSX is the latest step in KEF's continued development of cutting-edge technologies and innovative, high-performance audio products. 

Naturally, the speakers feature KEF's Uni-Q driver array, a 4-inch version is found here in each speaker. Additionally, there is KEF's highly advanced Music Integrity Engine, a cutting-edge collection of bespoke Digital Signal Processing algorithms that ensure accurate time alignment and phase coherence.

Cutting the cables

KEF LSXLSX is totally wireless both from source and between the speakers. Dual-band Wi-Fi (2.4GHz/5GHz) and Bluetooth 4.2 with Qualcomm's aptX codec enable streaming from Spotify, Apple Music (via AirPlay 2, coming in the new year) and Tidal. 

With Spotify Connect built in, you get access to the entire library directly from the cloud. 

Furthermore, LSX is DLNA compliant and boasts TOSLINK Optical and Auxiliary connections making it ideal for use with TV. Finally, setting-up is taken care of in a few minutes thanks to KEF's Control app, which also manages firmware updates as they become available.

Power play

The new LSX sports four Class-D amplifiers (2 x 30W + 2 x 70W), one for each of the drive units. Also under the hood are dedicated twin DACs providing a pristine signal path of up to 96kHz/24bit (using the optional wired connection between the two speakers) or 48kHz/24bit in entirely wireless operation.

The gently curved cabinets of the LSX was designed with extensive use of Finite Element Analysis as well as constrained layer damping as found in KEF's high-end audiophile products. 


Styling comes by way of a collaboration with designer Michael Young who has created a masterpiece of understated elegance. The result of Young's direction are the five colours to choose from - Black, Blue, Maroon, and Olive: Incidentally, they are also clad in a luxury fabric by Danish textile manufacturer Kvadrat. There is also a striking Gloss White option. 

The KEF LSX will be available late November 2018 and will sell in New Zealand for $2,199 RRP.
