KEF LS50 Wireless II Active Speakers

The Ultimate Wireless HiFi Speakers

LS50 Wireless II is more than a high-performance loudspeaker; it’s the perfect all-in-one speaker system. It reveals every detail of your favourite music, which you stream from any source thanks to wireless compatibility with AirPlay 2, Chromecast and more.

The award-winning LS50 Wireless II connects to Roon without the need of configuration, so you can enjoy bit-perfect high-fidelity sound with zero fuss.

LS50 Wireless II features the 12th Generation Uni-Q driver array featuring an industry first - Metamaterial Absorption Technology (MAT). This particular Uni-Q driver, whilst being inspired by that of the R Series, has been engineered with regards to the overall system design. 

The active LS50 Wireless II incorporates all the technology described for the passive LS50 Meta, plus a few extras that either add to the presentation of the music - making it even more accurate - or add to the functionality. The electronics, mounted on the back, includes two channels of power amplification (one channel for each driver and each of higher power than the original LS50 Wireless) and the KEF Musical Integrity Engine (MIE). This is essentially custom Digital Signal Processing (DSP) that allows the acoustic engineer to do far more than is possible in any passive design. Each stereo pair comprises a Primary and a Secondary speaker. The former incorporates adjustments applicable to both speakers, such as bass extension, room acoustic compensation, source selection and placement/EQ. Bass may be extended to lower frequencies than is limited by the usual passive cabinet-size/sensitivity trade-off, the balance may be adjusted for speaker position and room acoustics and the all-pass delay inherent in passive crossovers may be eliminated. All adjustments are made using a smartphone app. This is available for both iOS and Android devices and is a free download either from the Apple App Store or the Google Play Store as appropriate.

KEF KC62 Subwoofer

KC62 aka David. The Biggest Small Subwoofer. 

Through exceptional engineering and creativity, KEF engineers have developed a brand new approach and new technologies to accurately reproduce the original recording, bringing all the splendour, impact and emotion from music and films.

The cabinet is incredibly sufficient at withstanding a range of bass production, from deep thunder to quick and sharp agile bass without moving.

Don’t let the size fool you

Deep and powerful bass is no longer solely the domain of big-shouldered, massive subwoofers. Thanks to three innovative KEF technologies, the KEF KC62 Uni-Core force cancelling subwoofer has changed the rules of subwoofer design forever. Performance levels are at complete odds with this compact subwoofer’s football-sized dimensions, with unprecedented depth and breath-taking accuracy delivered in equal measures.

Uni-Core Technology

Craving an immersive entertainment experience but put off by bulky subwoofers? KC62’s patent-pending Uni-Core technology revolutionises the traditional force cancelling design to deliver deep accurate bass from an ultra-compact cabinet. Combining both drivers into a single magnet system allows cabinet size to be reduced by over a third, while also increasing excursion to unlock exceptional output and depth.

Turn up the Power.

KC62’s twin drivers are powered by 1,000W RMS (2 x 500W) of specially designed Class D amplification, providing exceptional levels of control and the ability to deliver sudden bursts of power when required, for example when enjoying your favourite high-octane action sequence.

5 Pre-sets.

KC62 slips effortlessly into any environment or listening room, with the five pre-set Room Placement Equalisation feature ensuring the same performance no matter where you decide to place it; in free space, next to the wall, in a corner, nestled within a cabinet or using the dedicated apartment mode.

Well connected.

KC62’s connection options allow it to be used with almost any audio system, with KEF SmartConnect and speaker level inputs eliminating any connection issues. Line output with HPF allows for exceptional fine-tuned integration, and KC62 is also compatible with the KW1 for simple wireless compatibility.
