1 pair KEF LS50 Wireless II black

Excellent condition, original packaging and accessories.  STANDS ARE NOT INCLUDED

KEF's original LS50 Wireless speaker system made waves in the audio world and was a huge hit with our customers, offering impressive sonic fidelity in a convenient, self-powered package. The new LS50 Wireless II retains the sleek looks while making some important tweaks for even better performance. For starters, KEF has increased the built-in power, with 280 watts for each woofer and 100 watts for each tweeter. 

Revolutionary sound absorption

This speaker benefits from KEF's new and innovative Metamaterial Absorption Technology (MAT). It's a highly complex, mazelike structure that's tuned to absorb unwanted sound coming from the rear of the tweeter. The resulting sound is clear, purer, and more detailed. 

Wireless music streaming options

These speakers are equipped with built-in dual-band Wi-Fi® and Bluetooth® 4.2 for easy music streaming. The free KEF Connect app offers access to popular music streaming apps, including Spotify® (via Spotify Connect), Tidal, Amazon Music, Qobuz, and Deezer. And internet radio and podcast listening are on tap as well. 

Wired connections

The primary speaker in this pair is equipped with the following high-resolution digital inputs for connecting external components:

• RJ-45 Ethernet port for network connection (accepts signals up to 24-bit/384kHz)
• HDMI eARC (24-bit/192kHz) for improving sound from a compatible TV
• Toslink optical digital input (24-bit/96kHz)
• coaxial digital input (24-bit/192kHz)

There's also an analog 3.5mm auxiliary input and a mono RCA subwoofer output. The speakers can be interconnected via Ethernet cable or wirelessly. (A wired connection allows higher-resolution 24-bit/192kHz playback.)

The LS50 Wireless II features a patented offset, flexible port for reduced midrange coloration.

A room-filling "sweet spot," thanks to Uni-Q technology

KEF's patented Uni-Q technology places each speaker's tweeter in the acoustic center of the bass/midrange cone. That lets the LS50 Wireless II create a detailed, accurate, three-dimensional sound image. In essence, it makes the "sweet spot" — the ideal listening position — much larger. Sit wherever you like! It'll sound fantastic.

Careful cabinet design

The LS50 Wireless II's extremely rigid cabinet uses smooth, curved surfaces that help the sound radiate outward without distortion. It also features a patented offset, flexible port for reduced midrange coloration. As with previous LS50 models, the cabinet uses a grille-less design to show off the cool-looking driver array and super-stylish color options.
