KEF LS60 WIRELESS

KEF takes all-in-one hi-fi to a whole new level

SPEAKER SYSTEM £5999

Upon unboxing the KEF LS60 Wireless we were transfixed by what is one of the most impressive-looking pair of speakers we have seen for some time. The first thing that strikes you is that the cabinets are extraordinarily slim. Excluding the plinths, each tower measures just 13cm across. When you consider the LS50 Wireless II standmounters are 20cm wide, that’s a considerable amount of shrinkage.

A slim cabinet calls for a slimmer-than-usual Uni-Q driver and KEF’s engineers have delivered a brand-new version of its trademark drive unit – the smallest the company has ever designed, combining a 10cm aluminium cone for the midrange with a 19mm vented aluminium dome tweeter. KEF has also added a tweeter gap damper and a new Z-Flex surround to aid dispersion and reduce distortion.

The tweeter uses KEF’s Metamaterial Absorption Technology (MAT). This is a maze-like structure placed behind the tweeter. Each ‘path’ in the structure is ‘tuned’ to absorb a specific range of frequencies. KEF claims that the paths help create an ‘acoustic black hole’, absorbing 99 per cent of unwanted sound.

To get enough bass from such a slim cabinet the company has called on its clever and also Award-winning Uni-Core driver array, designed to deliver maximum bass from small enclosures, combining force cancellation (the drivers are mounted back to back), a shared motor and two completely different, concentrically arranged voice coils (one for each driver).
