KEF Celebrates Its 60th Anniversary With the All-in-One (And Done) LS60 Floorstanding Wireless Speakers

The KEF LS50 may be the easiest active speaker to recommend.

I reviewed the Nocturne Edition of the Wireless LS50 back in 2019 and was impressed with what I heard:

I’m putting the KEF LS50 Wireless Music System at the tippy top of my recommended active speakers list in and around their price range. These are the kind of speakers that I recommend even if you haven’t heard them because they do what every speaker strives to do, which is get out of the way of the music by putting you, the listener, directly inside.

To celebrate their 60th Anniversary, KEF offers up the LS60 Wireless Speakers. Boasting 1400 Watts, a mix of Class A/B and Class D amplification, of total power with dedicated amplifiers for the newly designed 4″ 12th Generation Uni-Q driver with MAT driver array (Metamaterial Absorption Technology) that handles high and midrange frequencies, and two pair of KEF’s Uni-Core 5.25″ force-cancelling bass drivers per speaker. But the real all-in-one fun beings with support for Spotify Connect, Tidal Connect, Roon, QPlay, and Amazon Music, Qobuz, Deezer, and Internet Radio via the KEF Connect app with Wi-Fi, Apple AirPlay 2, Google Chromecast, and Bluetooth connectivity.

Look ma, no wires! Of course you need to plug the LS60 into power, but you can connect the pair to each other via WiFi (supports PCM resolutions up to 24-bit/96kHz) or Ethernet (supports PCM resolutions up to 24-bit/192kHz), and you can send them your digital source data via WiFi or a wired connection to the Primary speaker.

The Primary speaker’s network connection supports PCM resolutions up to 24-bit/384kHz, DSD, and MQA (but remember this will get resampled to 96kHz or 192kHz depending on how you connect the speakers to each other), while the Coax and Toslink inputs max out at 192kHz and 96kHz respectively. There’s also an HDMI eARC input for your smart TV, a pair of  RCA inputs for an analog source, while each speaker sports an RCA Subwoofer out if you feel the need to fill out the bottom end. The slim 5.1″ wide (without plinth) LS60 have a claimed frequency response of  31 Hz – 36 kHz (±3dB) with the help of DSP.

The KEF LS60 Wireless speakers come in Royal Blue, Mineral White, and Titanium Grey and will be available at the end of May 2022 priced at $7,000/system.
