KEF wireless II
KEF always pushes the technological boundaries in its mission to create the best possible sound. And, MAT is the physical manifestation of that drive. As a joint development project with the Acoustic ‘Metamaterials’ Group, MAT breaks entirely new ground in loudspeaker design. A genuinely revolutionary tool in the KEF acoustic armoury, ‘Metamaterial’ Absorption Technology. And, (MAT) is a highly complex maze-like structure that eliminates unwanted sound from the driver’s rear, resulting in a purer, more natural performance.

Eliminate 99%
Metamaterials are specially developed structures that use existing materials in such a way that they exhibit new properties. MAT’s tuned channels absorb 99% of the unwanted sound from the driver’s rear, compared to around 60% absorption from loudspeakers using different approaches. KEF wireless II
The innovative Uni-Core™ system overcomes the performance compromises when placing force cancelling drivers into a smaller cabinet. Uni-Core™ combines both back-to-back drivers into a single motor system. The overlapping, concentrically arranged voice coils allow for far more driver excursion than in other force cancelling design, unlocking more output and depth from less space.
Music Integrity Engine
KEF’s bespoke Music Integrity Engine aids all aspects of the LS50 Wireless II’s performance. This collection of bespoke Digital Signal Processing algorithms is optimised for the Uni-Q driver, enabling it to deliver a perfectly timed performance. Also, the built-in amplifiers have been developed in-house by KEF. Each tweeter 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.
Every aspect of LS50 Wireless II has been considered for acoustic benefits and from a design perspective. The curved baffle’s low-diffraction is precision modelled around the Uni-Q driver. And, eye-catching heat sinks and colour-matched ports located on the well-equipped rear. The top-mounted control panel designed to be stylish and functional. Owners of the LS50 Wireless may be wondering what’s new? The answer: pretty much everything. The original was fantastic, but LS50 Wireless II is better in every respect, with improved sound, better connectivity and usability. KEF wireless II
Listening
First impressions
The speakers warmed up, and Diana certainly sounded great, and I was impressed just how good the speakers sounded. There was incredible detail in the upper end, and mids were just right. The bass was excellent, but we both agreed it seemed a touch on the light side. We allowed thirty minutes of warming up and then decided to go with our favourite artists. The latest album, ‘Point’ from Yellow, was found, and we were ready for the session.
The music played and we sat back and enjoyed the performance and really were pleased at what we heard. And, said how easy its was to get high quality sound without the hassle of additional equipment. Meaning also, how cost was drastically reduced and making it a very affordable purchase. KEF wireless II
Cable change
The first thing we noticed, was the sound now came from the speakers with such a force. And it was pushing us out of the way so we could hear. Also, the sound was now different and had new life and energy. It seemed like we removed a ton of rubbish from within the speakers. And, now, heard only the music. The music had transparency, depth and colourful details that built up a beautiful 3D picture.
The sound was now impressive and a ‘different kettle of fish’ – as the saying goes. The music sounded excellent and had everything you could want. There was enough bass, and easy to listen without fatigue or overload in any form. And, now, a real listening pleasure in all the music that we played through the system.
Conclusion
It is a pity to lose the possibility of such an excellent sound by the failure to supply a decent power cable as a person will be losing out and missing so much. From experience, I know how vital a suitable power cable is to allow a component to show itself in all its glory.
