Even wireless speakers need some wires, and in the case of KEF’s new (and improved) LSX II Wireless HiFi Speakers, you can get away with just a pair of power cords.
Which is how I’d roll with the LSX II which will get you a host of wireless connectivity options including AirPlay 2, Google Chromecast, ROON, UPnP Compatible (ick), and Bluetooth 4.2. Wiring up the LSX II adds Spotify via Spotify Connect, Tidal via Tidal Connect, Amazon Music, Qobuz, Deezer, QQ Music via QPlay, Internet Radio, and Podcasts via the KEF Connect app.
The LSX II inherits its more fully-featured connectivity from KEF’s W2 wireless platform found in the LS50 Wireless II and LS60 Wireless speakers.
The LSX II speaker employ KEF’s 11th generation DSP-tweaked Uni-Q driver array driven by a combined 200 Watts of system power, with the tweeter and woofer getting their own dedicated amplifier. The LSX II adds HDMI ARC and USB Type C connectivity options to the Toslink and analog 3.5mm Auxiliary inputs.
The KEF LSX II Wireless HiFi Speakers will be available later this month for a suggested retail price of $1400/pair.
