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.
