PERFORMANCEMost accurate, immersive sound

When it comes to physical technology, LS50 Wireless II takes its lead from KEF’s LS50 Meta passiveloudspeakers. A truly revolutionary tool in the KEF acoustic armoury, Metamaterial Absorption Technology1(MAT) is a highly complex maze-like structure, where each of the intricate channels efficiently absorbsa specific frequency. When combined, the channels act as an acoustic black hole, absorbing 99% of theunwanted sound that comes from the rear of the tweeter, eliminating the resulting distortion and providinga purer, more natural sound

KEF’s Uni-Q point source configuration delivers a more detailed, accurate and integrated three-dimensionalsound image, which is dispersed so evenly throughout the room that the ‘sweet spot’ is wherever you arein the room. Using simulation and analysis tools, our engineers have developed the 12th generation Uni-Qwith MAT driver array, to reduce high-frequency distortion in the mid-frequency driver. The result is reducedcoloration, less distortion and a sound that is more transparent and life-like than previously possible. Theother frequencies are equally well served, with crystal clear midrange and room-filling, deep and articulatebass.

The performance of LS50 Wireless II is aided by KEF’s bespoke Music Integrity Engine, a cutting-edgecollection of bespoke Digital Signal Processing algorithms optimised for the new Uni-Q with MAT driverarray, enabling it to deliver a perfectly timed performance, for better imaging and a tighter, unsmearedsound.

LS50 Wireless II also has plenty of power on tap. Each tweeter benefits from being driven by a new 100Wclass A/B amplifier that delivers a smooth, incredibly detailed treble performance. Dedicated 280W class Damplifiers power the mid/bass drivers, for room-filling, controlled sound. The diligent amplifier developmenthas all been undertaken in-house by KEF, in order to completely control the quality of power on offer.The end result of this tireless effort is sensationally dynamic sound, with the music’s subtle ebb and flowdelivered in all its glory

DESIGNAttention to every detail

The LS50 Wireless II will also fit comfortably into your living space when it comes to style. The lowdiffraction, curved baffle is precision modelled around the Uni-Q driver array, while eye-catching heat sinksand colour-matched ports are located on the well-equipped rear. LS50 Wireless II is available in three mattfinishes, Carbon Black, Titanium Grey, Mineral White as well as a Crimson Red Special Edition. All the coloursare mirrored on both the drive units and the rear-facing port means the LS50 Wireless II looks fantastic fromany angle.

On the LS50 Wireless II’s underside, each corner has a threaded inset allowing the speaker to lock onto thetop of the new KEF S2 Floor Stands, which also boast integrated cable management and a mass-loadablecolumn. The stands are all colour matched to your finish of choice.For even more impact and bass extension, LS50 Wireless II features two subwoofer outputs, one on eachspeaker. When paired with KEF’s KUBE range or KF92 subwoofers, music and film becomes even moreimpactful.
