KEF LS50 Wireless II (sæt)

KEF LS50 Wireless II er en klar evolution af den meget populære aktive LS50 Wireless, designet til at håndtere og afspille musik i højeste opløsning, nu også MQA og DSD.

AirPlay 2, Roon Ready, Chromecast, Spotify Connect, Bluetooth, Tidal, Qobuz, Amazon, multirum - LS50 Wireless II er klar til det hele og nu helt uden forbindelseskablet mellem de to højttalere, noget som den oprindelige LS50 Wireless fik lidt kritik for.

Ønsker du den højeste kvalitet, så er forstærkeren optimeret med flere watt og DAC'en nu 24-bit / 384 kHz og håndterer både MQA (Tidal Master) og DSD256. Går du op i den allerhøjeste opløsning over 24-bit / 96 kHz, så kræves et forbindelseskabel mellem de to højttalere.

LS50 Wireless II er baseret på 12. generation af den berømte Uni-Q højttalerenhed som drives af en 100 watt klasse AB-forstærker (diskanten) samt en 280 watt klasse D-forstærker (bassen). Nu er maks lydtryk oppe på 108 dB.

Betjeningspanel på toppen af masterhøjttaleren samt medfølgende fjernbetjening.

LS50 Wireless II is more than 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.

No matter how you stream your music, LS50 Wireless II has you covered. You can stream directly from the Spotify native app with Spotify Connect. With the KEF Connect app you can also stream Tidal, Amazon Music, Qobuz, and Deezer or tune in to internet radio and podcasts.

Out-of-the-box wireless compatibility with AirPlay 2, Google Chromecast and more, backed up with wired connections for your TV, turntable, CD player and games console. Whatever source you’ve got, LS50 Wireless II is ready for it.

LS50 Wireless II has audiophiles covered with support for streaming music files up to 24bit/384kHz, as well as MQA, DSD256, and Roon Ready (coming soon). These features mean that even the experienced HiFi enthusiast will marvel at this exceptional loudspeaker’s ability.

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 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.

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.

LS50 Wireless II melts away, leaving you to enjoy the music. Revolutionary Metamaterial Absorption Technology eliminates distortion for a purer, more natural sound, while our 12th generation Uni-Q with MAT driver array delivers three-dimensional, wonderfully revealing sound anywhere in the room.

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

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.
