Music Integrity EngineAll aspects of the LS50 Wireless II’s performance is aided by KEF’s bespoke Music Integrity Engine. This collection of bespoke Digital Signal Processing algorithms is optimised for the Uni-Q driver, enabling it to deliver a perfectly timed performance, for better imaging and a tighter sound. |
Plentiful powerThe built-in amplifiers have been developed in-house by KEF. Each tweeter is 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. |
12th generation Uni-Q with MATUsing advanced simulation and analysis tools, our engineers have developed the 12th generation Uni-Q with MAT. This new driver array delivers reduced coloration, less distortion and a sound that is more transparent and life-like than previously possible, all dispersed evenly throughout the room. |
Personalised listening experienceThe brand-new dedicated KEF Connect app controls LS50 Wireless II on a day-to-day basis, including intuitive sound settings so you can tune the sound to your own personal tastes. You can even select your favourite source to wake up LS50 Wireless II whenever it comes on, allowing you immediate access to the best sound. |
What's New
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.

There was a problem filtering reviews right now. Please try again later.
It says a lot about the situation that I spent way less time setting up the new system than I did taking down the old one. I estimate that I replaced more than 170 lbs of equipment with around 40 lbs that this pair of speakers (including built-in amps and etc) weighs. So much less clutter! Setup was effortless and effective, the sound is better (and it was previously quite good, until recently, when my old power amp died) and the functionality is spectacularly better. This system offers an extremely simple and direct route to decent to very good sound (better at the price than I could achieve with lots of careful effort over many years) and all the functionality that I, personally, currently want.
I used an inexpensive old subwoofer with the old setup. I continue to use it with these new speakers. I think I would be happy without the subwoofer, but like the tiny bit of additional rich low-bass and kick that it provides.
That points to something that astonishes me about this system. The KEF Connect app equalizer made it very easy to account for the situation of the speakers in the room and to incorporate the subwoofer. I'm a software developer, and think they did an extremely good job with the human factors of the app. I don't need or want the app to provide the functionality that my streaming music players provide – as another reviewer said, let Google and App and Tidal, Roon, etc do that. I'm very pleased with how well the app does what I need it to do. Similarly, the remote control gives me a convenient way to adjust the volume, mute, and on rare occasions when the I need to override the automatic source detection, change the source.
I haven't yet said anything specific about the sound, and I'm still finding out how it is. So far, I'm delighted. I'm finding more clarity, richness, and dynamics than I've experienced before in my home. I continue to go through different parts of my collection, as the mood strikes, and discover myself enjoying aspects of the music that I hadn't noticed before. People often talk about the almost palpable imaging that Kef's coincident-centers Uni-Q drivers provide. It's true, and it enhances the experience. The thing is, I haven't found any downsides. As I said, they're still new, there's more to discover. But I'm happy. (-:
I've only had the speakers for a few weeks, and am wary of an "all eggs in one basket" dependency on them. I will be dependent on KEF and/or after-market repair services if something breaks. That said, this is KEF's second iteration of the model, which could mean that a lot of the bugs have been shaken out. Plus I was in a bind with the old system when my power amp died, and that's the case for any component in the multi-component chain. It's all trade-offs.
Ultimately, I got a high quality, exquisitely well-integrated system. Provided that they're reliable, for anyone who streams music in their home, these are the best prospects that I've encountered for getting high fidelity and high functionality at anywhere near this price, more so than anything else I've seen up to now.
Enter the LS50 Wireless II. As soon as I turned them on, I could already tell the openness they provide as well as the detail. Every note is the, not hidden not muddled but very clearly present. Even pushing then to 95% volume I noticed no sound distortion.
With classical and jazz music, I feel like I'm in front of the band and the instruments truly come alive. Electronic music also pops right out, although I suggest a sub to open them up a little more.
Overall, supremely surprised and absolutely enjoying these speakers. I was expecting a lot and I'm happy to say they surpassed my expectations.
I had the original LS50's for years, and loved them. Since almost all of my listening is from DAP or streaming, I decided to scale-down, sell my LS50's, amp and subwoofer, and move to the new wireless speakers.
The sound is just amazing. Speakers this small shouldn't be able to have great sound AND imaging. Placement matters a little, I have mine 8' apart, and about 6 inches from the wall. And the room does matter, but that's true of all speakers. My listening room is about as bright as you can get, choosing the "bright room" EQ fixed that with no tweaking.
For some reason, KEF didn't put a USB in jack on these. That's a miss, IMHO. You can work around it, but should you have to? Even the LSX's have USB.
The software is good, but not great. Setup and interface are easy to learn, but overall, kind of messy. And the software pretty much assumes you're using one of the supported streaming services. I prefer to use the soft-buttons on the master speaker, when using a DAP.
Overall, at least for me, at the sale price of $1999, these are just crazy-good.

Of course, things are good things, and there are a lot of comments on the Internet, so I won't say anything. But after opening the box, the pungent chemical smell has not dissipated for a few weeks after opening the window. It is a defect, right?
