KEF LS50 Wireless II £2249
The LS50 Wireless IIs are sequels to a product that we regarded highly enough to be our first What Hi-Fi? Hall of Fame entry. The LS50 Wirelesses are an active speaker system take on KEF’s LS50s – wireless stereo speakers with built-in amplification and streaming smarts – and the Wireless IIs squeeze even more performance out of that familiar chassis and Uni-Q driver arrangement.
They do this through the introduction of an innovation called Metamaterial Absorption Technology (MAT), a clever way of absorbing sound waves radiating from the rear of the tweeter dome so they don’t distort the unit’s output.
This involves a round piece of plastic with a maze-like structure behind the tweeter. Each ‘path’ in this structure is ‘tuned’ to absorb a specific range of frequencies. KEF says that, together, the various paths absorb 99 per cent of unwanted sound.
