![]() ![]() These are decent figures for a speaker its size and type, although you'll need a gutsy solid-state amp to really get the best from it. Aside from the crossover point shift from 2.2kHz in the original to 2.1kHz with the Meta, sensitivity remains at a quoted 85dB, with a maximum output figure of 106dB KEF says the frequency response is 47Hz–45kHz (-6dB). If you want to know more, then you can read this article along with this white paper released by the Audio Engineering Society in June 2020.Ĭomparing the specifications between the original LS50 and LS50 Meta, and they're as good as identical. This paved the way for a refresh of both its original LS50 and LS50 Wireless models that would see MAT implemented in the twelfth generation UniQ driver. I had been wondering what KEF's LS future roadmap might look like, until the late 2020 announcement of the company's new “world-first technology” in the form of its Metamaterial Absorption Technology (MAT) breakthrough. There have been other additions to the LS family since, including the LSX Wireless – a smaller, not-quite-as-capable version, but one that's still highly rewarding in its intended application. ![]() For the best part of a decade, it was a magic that enthusiasts often struggled to find. KEF had taken a marvellous speaker and elevated it to another level, thanks in no small part to the synergy between processing, power amp and drive unit. I reviewed the LS50 Wireless upon its release and had only positive things to say. Then in 2017, the company did what everyone expected in the digital age and stuck a couple of amplifiers, some clever digital signal processing, and the next generation of the famed UniQ driver in that same small box. If only a design such as the LS50 existed when I and many others started our hi-fi journeys, I suspect many dollars would have been saved along the way. That such a diminutive box produced such a delightful, full-bodied sound – and went louder than it should, and with more low-end response than you'd think physics allowed – was impressive. ![]() It quickly garnered much fanfare of its own accord, which was surely well deserved. The truth is that its use of KEF drive units is where the similarities ended – the LS50 was very much its own design and not an attempt to mimic anything else. When KEF launched its striking little LS50 standmount loudspeaker ten or so years ago, there was a lot of chatter about BBC monitors, with links to the famous LS3/5a and so forth. ![]()
