The KEF LS50 wireless is an all-in-one active speaker system featuring dual 24/192 DACs, dual-mono amps, and dedicated DSP crossover per speaker. A killer audiophile system in a small footprint?

KEF LS50 Mini Monitor Preview


Preview: The thing that makes the KEF LS50 mini-monitors so exciting is the price. $1500 a pair may sounds reasonable to us given the level of technology that has gone into KEF LS50s.

Mini-monitors are designed for near-field listening so the KEF LS50s are probably not going to speakers that you'll place in your home theater. KEF spec's the LS50s down to 79Hz at -3dB and 47Hz at -6dB. This is a pretty amazing response for a...

KEF LS50 Loudspeaker Review


KEF, based in the U.K., enjoys status as one of the most respected, and long-lived, speaker manufacturers in high-end audio. The company has designed and sold some of the best-known speakers in the history of the hobby. They have multiple lines they...

KEF LS50 LoudspeakerReview


For a 50+ year old company, KEF sure can innovate. Their latest bookshelf loudspeaker will have the competition crying in their pudding.

With the Denon AVR-591, I heard a hardness in the treble that could become irritating over time, but as I listened to more and more products, I realized that the LS50's capabilities are only limited by your choice of amplifier and source. For a $1,500...

KEF LS50 Wireless review


The KEF LS50 Wireless gives you the performance of a top traditional system in a smart package...

Impressive clarity and insight ; Taut bass and strong dynamics ; Features and excellent build ; Neat package

Some small usability issues

These KEF Wirelesses are way more than just active versions of the award-winning LS50s. They’re a complete system wrapped in a neat and brilliant package

Awards 2012 Product of the Year - Stereo Speakers. A fine way to celebrate KEF's 50th anniversary

Transparency, impressive resolution ; excellent bass for size ; fine build and finish

Demanding of partnering equipment

Of course, the LS50’s innate transparency means that any flaws in the partnering kit will be apparent. But get it right and you have what is one of the best standmounters below £1000, and easily one of KEF’s most musical efforts in years.

European Loudspeaker 2012-2013


To casual viewers the LS50 will look like a minimalist, single-driver loudspeaker but in reality it's more sophisticated. In fact, this single driver is one of KEF's famous two-way Uni-Q units with its tweeter mounted at the acoustic centre of the...

KEF LS50 Speaker Review


The LS50 speaker is KEF's 50th Anniversary present to itself but is it a case of many happy returns?

Wonderful midrange performance ; Excellent integration ; Handsome looks

Dependent on decent partnering equipment ; No dedicated stand ; Not terribly sensitive

The KEF LS50 has been on sale for a little while now and I have heard it in passing at various shows and events. I had never truly managed to get a complete handle on the LS50 despite being reasonably impressed with what I heard. I was also a little...
