KEF Unveils ‘Fully Wireless’ Compact Speaker System

KEF today announced a “fully wireless” follow-up to its award-winning LS50 compact wireless speaker system that uses a wireless connection between speakers instead of the usual clunky cable.

The new app-controlled LSX system ($1,100 for two speakers) shares much of the acoustic engineering used in the LS50, winner of EISA’s 2017-2018 Best Wireless Loudspeaker Award, and features a newly refined version of KEF’s signature Uni-Q driver array, which combines a 4-inch woofer with a concentric tweeter to “improve stereo imaging across a much wider listening area.”

The speaker also incorporates KEF’s Music Integrity Engine, described as a collection of digital signal processing algorithms that “ensure accurate time alignment and phase coherence.”

In addition to wireless streaming via Bluetooth/aptX and Wi-Fi, the LSX supports hi-res files up to 24 bit/192 kHz and will be updated to support AirPlay 2 wireless streaming for Apple devices in early 2019. The system is DLNA-compliant and delivers 200 watts of power via four amplifiers (2 x 30 plus 2 x 70 watts) — one for each tweeter and woofer.

System setup is accomplished using the KEF Control app — available for iOS and Android — which also manages system updates via wireless downloads and provides adjustable EQ settings. Connection options include an optical digital input, minijack auxiliary input, and a subwoofer output.

The LSX’s gently curved cabinet, designed using Finite Element Analysis, is extensively braced and employs the same constrained-layer damping techniques used in KEF’s high-end speakers. The speaker is offered with a gloss white finish or clad in black, blue, maroon, or olive colored fabric from Danish textile manufacturer Kvadrat.
