About the KEF LS50 Wireless

A gorgeous, versatile high-end audio solution

KEF LS50 Wireless powered speakers stand out from the crowd. They have a lot to offer, and when we heard them at our Charlottesville HQ, they really grabbed our attention. They're beautiful, compact, easy to use, and versatile enough to form the core of your everyday sound system. And you won't believe the rich, detailed sound they produce.

A gorgeous, versatile high-end audio solution

KEF LS50 Wireless powered speakers stand out from the crowd. They have a lot to offer, and when we heard them at our Charlottesville HQ, they really grabbed our attention. They're beautiful, compact, easy to use, and versatile enough to form the core of your everyday sound system. And you won't believe the rich, detailed sound they produce.

Audiophile sound quality

When you're going for that magical level of sonic realism that can raise goosebumps, one of the biggest challenges is matching the right amplifier to your speakers. So KEF has eliminated the guesswork: they put two custom-designed amplifiers in each speaker — 200 watts to each woofer, and 30 watts to each tweeter — so each driver gets perfect power. And the attention to detail doesn't stop there. Each driver has a high-end 192 kHz/24-bit DAC to make digital sound come alive.

Built-in digital signal processing (DSP) offers an easy Beginner mode, but you may prefer to take total control in Expert mode, and tweak the sound to perfectly suit your unique room. Whichever way you choose, you can make your changes via a free smartphone app, available for Apple® and Android™ devices.

Praise for KEF LS50 Wireless speakers from

"Something for audiophiles, something for mainstreamers – after all, it's in the LS50 Wireless' DNA. As a straddler of worlds, the KEFs walk away not only with a Knockout Award but also DAR's Product of the Year award for 2016. If this product doesn't convince audiophiles of the legitimacy of active loudspeakers, nothing will."

A room-filling "sweet spot," thanks to Uni-Q technology

KEF's patented Uni-Q technology places each speaker's tweeter in the acoustic center of the bass/midrange cone. That lets the LS50 Wireless create a detailed, accurate, three-dimensional sound image. In essence, it makes the "sweet spot" — the ideal listening position — much larger. Sit wherever you like! It'll sound fantastic.

My hands-on experience with the KEF LS50 Wireless

I originally heard these speakers in our spacious training room at Crutchfield HQ, then enjoyed them later in a smaller conference room. Nothing prepared me for what they'd sound like in my own home.

I fussed for a while, trying them on different stands before deciding to place them on either side of the TV, directly on the entertainment furniture. Easy-to-use Speaker EQ buttons on the back of the right-hand speaker let me quickly customize the speakers' sound to suit each location change. The free KEF LS50 Wireless app was there to help me further tweak the output so it sounded full and clear in my living room — an open-plan, more-or-less rectangular space with glass along one side.

Once I had the basics taken care of, I started to have fun. I elected to stream some dynamic, demanding tunes via the built-in Spotify Connect, and they sounded amazing. The bass is reasonably deep and accurate when using the speakers alone, but it's a good idea to plug a subwoofer into the provided outlet to get the full experience from music and movie soundtracks. Cellos and violins sound heavenly in string quartet selections. I've revisited every one of my favorite jazz singers, just to hear the vocal nuances the LS50s can uncover. They dramatically expand the soundstage and reveal detail in every track I play.

If you have limited space, but want to enjoy your music to the fullest, these speakers make a big, beautiful sound that belies their relatively small footprint.

Customizable room EQ with the free app

KEF knows your room is unique, so they've put the power of choice in your hands. Just download KEF's free app, and you'll be able to tune the speakers to suit your space. Once you've made all the big adjustments, you can revisit and make manual tweaks to your heart's content.

KEF LS50 Wireless powered speakers offer a variety of connection points, so you can choose how you want to use them.

KEF LS50 Wireless powered speakers offer a variety of connection points, so you can choose how you want to use them.

Convenient connections

Think of a way you want to use these LS50 Wireless speakers, and you'll likely find a connection to make it happen. Want to transform the sound from your TV? Run an optical digital cable to the back of the right-hand speaker. Enhance computer gaming by plugging your machine into the asynchronous USB port. You can even run the output of your phono preamp into the RCA inputs and enjoy your favorite records.

Or, you can skip the wires altogether and stream your favorite high-res tunes through the LS50 Wireless' Bluetooth® connection. Or use your home's Wi-Fi® network to play music files from a DLNA-compatible computer or music server. The left and right speakers share audio signals via an included Ethernet cable.

Did we mention that they're super-stylish?

LS50 Wireless speakers come in three attractive color combinations, so they'll delight your eyes as much as they do your ears. Each has a curved front baffle that adds a touch of elegance to your shelf or speaker stands. Even the most design-conscious homeowner can find a prominent place to display these beauties.

Audio Section

Uni-Q Driver Array: The LS50 powered speakers feature KEF's patented Uni-Q driver configuration, in which the tweeter is mounted at the acoustic center of the midrange cone. With both acting as a single point source, the sound is dispersed widely and evenly throughout the listening area allowing you to experience superbly defined and perfectly balanced stereo imagery with a wide "sweet spot". The Uni-Q driver array is made up of a 1" aluminum vented-dome tweeter and a 5.25" magnesium/aluminum alloy cone woofer.

  • 1" Aluminum Vented-Dome Tweeter: The geometry of the tweeter dome matches that of the midrange cone to avoid disrupting the waveform. By smoothening high frequency response, this helps to account for the detailed and strikingly natural-sounding treble. The 1" aluminum vented-dome tweeter utilizes a Tangerine Waveguide to encourage the sound to radiate spherically for wider, more even dispersion so that everyone in the room enjoys the same superb sound quality. A large internal vent prevents potentially distorting high pressures from building up behind the dome in the critical vocal region, preserving all the nuance and fine detail of the original performance.
  • 5.25" Magnesium/Aluminum Alloy Woofer: The 5.25" woofer uses a magnesium/aluminum alloy cone that is light, stiff, and smooth for natural midrange and midbass sound. A well as allowing the midrange cone its full extension, KEF's ingenious Z-flex surround guides the sound from the tweeter across the surround without any disturbance or secondary radiation. Treble response is clearer and sweeter.
Note: The LS50 powered speaker system does not include grilles.

Bi-Amplifier Configuration: The 1" aluminum vented-dome tweeter and 5.25" magnesium/aluminum alloy woofer are powered by an incredible clean and fast 230 watt amplifier in a bi-amp dual mono configuration (200 watts to the woofer and 30 watts to the tweeter) that produces high-fidelity sound.

Note: Because the LS50 Wireless speaker system is self-powered, each speaker will need to be plugged into an AC wall outlet.

Advanced Time Correcting DSP: The LS50 Wireless employs an advanced time correcting DSP crossover that corrects for inherent time delays introduced in the crossover stage.

FEA-Designed Cabinet: The FEA-designed cabinet with its constrained layer damping bracing and precision engineered curved baffle, along with the elliptical flexible port all work in concert to prevent cabinet vibration and resonances that produce unwanted sound coloration for clear, spacious, distortion-free sound.

  • Curved Baffle: The curved baffle is shaped so that the sound waves spread from the drivers with minimum reflection from the edges which gives a very nice spacious sound. The curvature also improves the rigidity of the baffle which reduces vibration and sound coloration.
  • Constrained Layer Damping: The constrained layer damping which is between the brace and the enclosure walls and also the front baffle, prevents the cabinet from vibrating and radiating sound. This helps to prevent coloration in the midrange.
  • Flexible Port Tube: The rear-firing port tube has a flexible wall which allows midrange sound that is travelling down the port tube to escape back into the cabinet and prevents longitudinal resonances; which can otherwise radiate and cause midrange coloration. The port tube also has very carefully flared walls to avoid the chuffing noises that you can hear when you get air turbulence inside the port.

24-Bit/192kHz DACs: The LS50 Wireless features an end-to-end 192kHz/24-bit high-resolution digital signal path with two separate DACs for each speaker, for a total of four for the pair.

Speaker EQ: The LS50 Wireless speaker system provides a built-in Speaker EQ to tailor the sound of the system to the placement of the speaker. Select from "Desk", "Stand", "Wall", or "Free Space".

Advanced Audio Settings: Through the KEF LS50 Wireless app for Apple iOS 8.0+ and Android OS 4.1+ you get access to advanced  audio settings to expertly tailor the system's sound to your room environment and preference.

  • Room Acoustics: You can select the size of your room (Small, Medium, or Large), as well as indicate the room setting (Damped, Moderate, or Lively). In addition, you can indicate how far the speakers are from the back wall.
  • Bass & Treble: You adjust the treble trim from -2dB to +2dB. The bass extension can be set to Less, Standard, or Extra. There is also phase correction between the two speakers.
  • Sub Controls: If you connect a powered subwoofer you can activate a variable high pass (50-120Hz) & low pass (40-250Hz) crossover. You can also adjust sub polarity and sub gain (-10 to +10dB), as well as the balance between subwoofer and speaker.

Tethered Cable: The speakers are labeled "RIGHT" & "LEFT". The included 10' Cat-6 cable plugs into the back of each speaker to connect them together as a stereo pair. You can set the balance between the Right & Left speaker.

Subwoofer Output: The KEF LS50 Wireless speaker system is equipped with a mono-RCA subwoofer output to connect a powered sub (sold separately).

Do these speakers have apple airplay?
[ Jared  Oct 21, 2020 ]
7 answers
You likely know the LS50 is out of production. The documentation i have with mine (purchased FEB2019) mentions 'Dedicated apps for iOS and Android', '2.4GHz/5GHz Dual-band Wi-Fi connectivity', and 'Bluetooth 4.0 with aptX codec', whereas the KEF website specifically says the LS50 Wireless II is compatible with Airplay 2. That's what i know. i guess the short answer is 'I don't know'. I've always used only the optical wired connection on mine. Before purchase I did submit a question to KEF, through their website, about their subwoofer and received a prompt, accurate response.
[ Robert  Oct 22, 2020 ]
They don't have Apple airplay, but the regular Bluetooth they do have works quite well.
[ MARK  Oct 22, 2020 ]
[ Harrison  Oct 21, 2020 ]
No, they do not.
[ Glen  Oct 21, 2020 ]
No, they don't. BUT, I have an old airport express hooked up to them through an optical cable, and am able to airplay that way. Works great. My primary setup is direct out of MacBook. And can then use my iPhone remote app to control. Not ideal. But works, and sound is arguably better that way.
[ CHAD  Oct 21, 2020 ]
No, although I was able to work around that using an airport express via the optical output
[ Scott  Oct 21, 2020 ]
I don't know. I don't have Apple airplay. I use Bluetooth
[ Stephen  Oct 21, 2020 ]
I am very impressed with all the reviews and want o order the LS50 Wireless pair. I want to listen to Hi Res music though Tidal/Qobuz from my iPhone via WiFi. But sounds like the LS 50 has WiFi issues and cannot stream HiRes content from WiFi connection. Most people are using this with a direct USB connection and they don't have this issue. To get around the streaming problems, do I need an external streamer like a Bluesound Node 2i?

I am very happy with these speakers. Im 67 years old and went through the stage where i had to have the very best my wife would let me afford. My best was Magnaplaners and "son of Ampzilla" with pre-amp, Top of the line Tecnics turntable with Shure's Best cartridge. When i turn my LS50's up loud the sound is comparable. And all i have to do is load apple-play and im good. I tried the $20 a month hi quality digital sound and chose to stay with Apple-play for $10. The only negative i have is remote control changing volume and input selection from my couch is less than ideal but the sound i get from such a small speaker is worth having to get up to move closer to the speakers with the remote. As far as usb and bluesound, Im happy with my bluetooth connection.
[ Daniel  Jun 07, 2020 ]
Hi Charlie, Crutchfield requested i answer your question, but i don't know anything about the limitations of wifi in your case. I've never even tried to connect mine wirelessly. I bought these knowing a cable connection is possible, allowing me to avoid more-glitchy wifi. Sorry couldn't help. good luck
[ Robert  Jun 05, 2020 ]
I stream Tidal Hi Res via my Roon music server to the LS50s without any problems. I setup everything over two years ago and have not touch it since.
[ Robert  Jun 04, 2020 ]
I am not to sure how to answer your question. But I would recommend calling KEF themselves they are very helpful
[ Ian  Jun 04, 2020 ]
I have them connected with ethernet cable to my router splitter. I get hi res playback. I also use Roon software, so I am not sure if that impacts this stream. Roon software core is on IMac, but I can control from iPhone, iPad etc. I would recommend to always used a wired connection to audio equipment, unless not possible. You should not need a separate streamer, unless you want to send signals to multiple playback options.
[ David  Jun 04, 2020 ]
So I'm not an audiophile, wish I was. I've been intending to buy used B&W CDM9s or Sonos Faber 2.5s. Are these better than a decent wired tower?
[ Aaron  Mar 29, 2019 ]
4 answers
Short answer is yes, but it depends on what you're looking for. On their own you'll get much better clarity, balance, and probably general sound quality in a small to medium sized room, but they may struggle a bit more if you're trying to fill a larger room. That said, I use them with an SB-4000 subwoofer in a pretty large loft room and find that combination to be much superior to any tower-based speaker system I could put together for a similar price.
[ Braeden  Apr 17, 2019 ]
I use the KEF LS50W in a nearfield (desktop) environment - hooked up to a computer via a usb cable. They have an excellent sound stage, adequate bass. I can't compare to other systems. I will say that these speakers grabbed me with their musicality. I can listen for long periods of time without listening fatigue.
[ RAYMOND L  Mar 30, 2019 ]
These are truly impressive, fantastic sounding speakers. ...but I ended up returning mine for a good old amp and wired speakers. I found the wired ethernet cable that connects these together troublesome and unsightly for my particular setup. I would have dealt with that nit picky wire issue had I not also experienced some spotty wireless connectivity issues. For what it's worth none of my other wireless devices in the same location had problems. Personally, at this price I was not willing to accept any interruptions in my listening time! Now very happy with my NAD/Monitor Audio 2Ch setup. Fantastic service through this whole experience, by the way, from Crutchfield. Happy listening.
[ Jesse  Mar 29, 2019 ]
Very nice speakers but they work best in a small to medium room and in my opinion really need to be paired with a musical 8" o 10" subwoofer to make them shine. I tried several subs and landed on the REL T7i being the best match for me.
[ Michael  Mar 29, 2019 ]
The part I have trouble picturing is the speaker interconnect ethernet cable. Mine will be on 24" stands. Will I be looking at a cable dangling between the two speakers?
[ Rich  Oct 04, 2018 ]
10 answers
Yes, you'll have at least two cables connected to each speaker, an Ethernet cable and a power cable, and the Ethernet cable needs to connect the two speakers. The supplied Ethernet cable is 3m long but you could always get a longer one, and the power cords are standard 15A IEC cables; depending on your stands and how far apart you're putting the speakers, you might be able to run the cables down along (or even inside) the stands to make the whole thing look neater....
[ Jon  Oct 05, 2018 ]
You could always get a longer cable and run it down one stand, across the floor, and back up the other stand. But yes, the two speakers have to be connected via an ethernet cable.
[ Stevan  Oct 05, 2018 ]
The cable is about 8 feet, but it has standard RJ45 connectors, so you can always get a longer one if necessary. I hide mine by taping it to the back of my stands.
[ Stephen  Oct 05, 2018 ]
I can't recall if the Ethernet cable is a special cable or just regular eithernet cable. But if it's regular, I would just use a longer length and hide it on the back of the stands and run it across the floor where it wouldn't be so noticeable. Nonetheless you still have to use it some how.
[ Robert  Oct 05, 2018 ]
Hello Rich, the interconnect cable does connect the two speakers. For me, I have no problem hiding the cable, as I have a piano between my speakers, which are mounted on stands. That said, I strongly advise not letting this be a show stopper, you find a better sounding set of speakers at this price point. I've read some reviews that have said they have tested $10,000 - $50,000 systems that don't sound this good.. Hopefully, that helps.
[ Robert  Oct 04, 2018 ]
First let me say theses speakers are truly amazing. As far as the cables go - yes there are cables running between the 2 speakers. You should be able to disguise someway. I have to be honest - I'm an audiophile - love Blues and Jazz. Speakers are worth every effort to make them work for you. Try to figure out how to hide the cable. Mine are in bookshelf so not an issue.
[ Andrew  Oct 04, 2018 ]
Well, there is a cable, but it is no different than a speaker wire that would be coming from an amplifier. The interconnect cable is fairly long and you may be able to get it out of sight by running it up along the legs of your speaker stands.
[ Thomas W.  Oct 04, 2018 ]
Since the internet connect cable is Ethernet like you said I just went and bought 5 ft cable from Amazon. My speakers do stand on KEF stand but because the cable is long enough it does drop down to the floor so you don't see the cables haning in mid air.
[ Du  Oct 04, 2018 ]
Yes, you can use a longer cable and have it routed through your stands and the floor. Mine are on a desk so the cable can be hidden. Thank you
[ Vincenzo  Oct 04, 2018 ]
They come with an ethernet cable that connects the two speakers. I think it's 15ft long. So it depends on your placement. I bought a longer ethernet cable; and placed it thru the hollow poles in the stands down to the floor then tucked it discretely between the base-boards and the carpet along the wall/floor, then back up the other hollow speaker stand to the other speaker. If done properly your cables can be well out of sight. Or at least as minimal as a traditional amp/speaker configuration.

i have a polk soundbar and generally not happy with the zippy tone (too much high-frequency sizzle) - would this be a good replacement as a TV "soundbar"? also, can you integrate a subwoofer easily? i.e., active low-pass x-over? how would you integrate the sub when there is only cable box, tv and firestick as sources?
[ PATRICK  Aug 19, 2018 ]

Plug the cable box and Fire stick into the TV and run an TOSLINK cable from the TV to the speakers. The LS50W has a sub out with an active crossover that can be tweaked in the app.
[ Stephen  Oct 05, 2018 ]
The subwoofer connects directly to the speakers themselves and you can configure the crossover from the app. Whether it's a good replacement for a soundbar is purely subjective. Sound quality wise yes it's better but it will not provide that same surround DSP effect.
[ Ronnie  Aug 19, 2018 ]
I use it for my computer set up. for that it is great. It would probably be good for a TV set up too. You would connect it via optical out. I am not sure if you can easily use a sub with it however.
[ Aaron  Aug 19, 2018 ]
These speakers will give you a much better sounding system than a soundbar. You can simply connect a subwoofer to the the back of the right speaker (there is a connection for that) and the iPhone or Android app can set up the rest like frequency cut over etc. Only draw back for this system is that you can not power the on the speakers with a remote. You will need to physically touch the power button every time.

Hi Paul, thank you for your question. Since the KEF LS50 speakers are powered, and have their own built in amp, they will not be compatible with a connection to an amplifier. Feel free to chat with an Advisor online or by phone at 1-800-324-9695. They will be happy to answer additional questions on these KEF speakers, or check out some speaker options that would be suitable to be used on your Sonos Amp.

As speakers they are wonderful: full bodied sound. First rate. They are wonderful with music wired or wireless from any source. I use them with TV and they're great. They sound like speakers that would sell for many multiples of their price. That said, they are NOT surround sound -- just good ole stereo. But they image so well, I love them. Good bass. If you want thunderous bass, you can always add a subwoofer to them.

These are way better. I have them and can attest to their magnificent performance. You can also check some of the high end reviews (Stereophile, Audiophile, etc. and they compare these to some of the best $10K - $50K systems that they have heard. Buy them, you won't regret it.

Sell your DAC, get these speakers.
[ Robert  Dec 27, 2017 ]
No: it does have a pair of RCA jacks for analog input, but that input is converted to digital so it can do some DSP and ship the signal to the left speaker via an Ethernet cable.
[ Jon  Oct 22, 2017 ]
Unfortunately you can't. It's really for those ho want the all in one solution. If you have a better standalone DAC, you're better off with the passive version.
[ Ronnie  Oct 21, 2017 ]
A need a DAC with RCA out and then input that signal to KEF's RCA input. This will bypass the KEF DAC.
[ HARVEY  Oct 21, 2017 ]
Yes you can, they have analog rca inputs, but know that they will be digitized again within the speaker. I have read online that some people did like/prefer the sound vs. the speaker as a stand-alone. But I will tell you the converters and electronics are so good in them, you probably won't want too. Highly recommend.
[ Kevin  Oct 21, 2017 ]
No, however you would not want to. I had the Auralic Vega DAC ($3,500) and sold it together with Focal Speakers. Even if your DAC is better the sound coming out of the speakers likely would not be. There are other factors. For one the Built in DAC has a built in DSP to correct for phase shifts. An external dac does not. Secondly, the short digital wiring from the internal DAC to the speaker Amp has much less Jitter than the output wire of an additional external wiring would add. If you really want to get the best sound possible out of these things there are some critical things you could do that would improve the sound tremendously. Get the ISO accoustic 150 (newer delux version) stands. Secondly get IFI micro iUSB3.0 (and for further 10% improvemnt the Igalvanic too). Use shortest possible usb 3.0 cables. No more than 3.0 feet. Amazon Basic is really good. A great 2 head USB2.0 cable is the Pangea premium in comes in .5 meters 199. If it is a computer based system get the Dirac Live software to calibrate the system. MiniDSP sells a calibration mic for under $100 that is really good for the price. Get a good stand with decent weight. If you do get the calibration system you can change the ethernet cable the speaker is using to Audioquest Cinnamon (this will not be advisable unless you are calibrating the system since the cable with the speaker goes with the current settings characteristic of the speakers). If you sold your DAC and did all that your system would be better by another dimension.
[ Aaron  Oct 21, 2017 ]
No you can't. I would consider buying the plain ls50s if you already have your own DAC.

I use my KEF speakers for my home office. Each speaker is placed to the left and ride side of my 32" monitor. The bass response and sound clarity are fantastic. While this system doesn't have a dedicated subwoofer, I still enjoy the full, rich sound from these speakers. The speakers are definitely a huge upgrade over anything I have used before. With a USB cable, I can connect directly to my iPad or PC and use a lossless streaming service to enjoy HD quality music. The DAC built into the KEF powered speakers is very good, as is the amplifier. So, I don't know your exact scenario, but I am very happy with the speakers. I purposefully picked this version over the newer ones because of the USB input.

Carl - Although on both my Windows and Apple computers, I connect these via the USB port, I have to believe that the sound card is involved in some way because volume and playback controls are available on the computer.

Hi, I just bought the LS50W. In the app, what do stand/desk, distance from wall/table actually change in audio terms (treble, mids etc)? I understand "lively room" means cutting down treble, and a large room size setting extends more bass . Also, if I want more mids, how do i adjust in app? Also, my ls50w sits on an iso acoustics aperta stands which sits on a desk. Should I set it to "stand or desk" in this case? Thanks a lot.
[ Waychai  Jul 12, 2018 ]
5 answers
Hi Waychai. Congrats on your new speakers and the iso acoustics stands are fantastic and a "must have" accessory. I would just go to the experience/advanced tab and turn on the stand AND desk tabs and experiment with them. On a desk, you might want them both on and start attenuating around 3db each as a start. Bass can get really boomy and tubby on a desk, especially when placed close to a rear wall. Trust your ears. ?? Try doing that AND adding a bass boost if you wish. That should help to keep your midrange clean.
[ Kevin  Jul 16, 2018 ]
You'll want to take a look at the excellent videos on the KEF USA site to find the answeres to your set up and adjustment questions. Take a look at the LS50 videos of the KEF USA site I don't have an answerer to your question about the use of the Apreta stands, suggest you let your ears decide which sounds best to you.
[ Paul  Jul 16, 2018 ]
Low frequency response is altered by the desk/stand and distance from a rear wall. The LS50 Wireless compensates for the effect close boundries. Mid frequencies are not altered, but the midrange might seem more correct with proper low frequency attenuation. The high frequency compensation corrects for shortwave length effects of room acoustic no matter where the speaker is placed. Proper high frequency compensation can also improve the midrange impression.
[ Ed  Jul 16, 2018 ]
Personally I use it for my computer system. I leave everything at default and adjust through DIRAC LIVE calibration program that I have in my Computer. External calibration will provide best results. If you do not have an external calibration you can adjust it in the software app. Use the EXPERT mode. I would start by leaving desk and Wall mode off. There you can adjust treble and Bass separately. If you feel you need more adjustment try putting desk mode on and readjusting treble and bass. Again this can help get you a better results but it will absolutely not come close to a real external calibration product.
[ Aaron  Jul 16, 2018 ]
I'm not entirely sure if the settings or advanced settings have a provision to set the midrange. But I find the best way to manipulate the settings is to just experiment with all of them and see what you like. You can definately hear a difference. I interprate the speaker stands setting as deliberate and standing in free space. As long as your higher off the desk and somewhat away from the rear wall, you are in free space and I interpret that as the stands setting. But again just listen for yourself. At the end of the day in home audio, if you like the sound then just enjoy it.

I only know the answer for using wifi as the input source. Yes, you will have to turn on the LS50W manually for that input source. The LS50W doesn't have the feature to wake up by wifi connection request. As for shut down, it will shut down after not using for a while. I don't know how long.
[ Lennart  Oct 28, 2017 ]
No. It doesn't have auto on. But there is a time out . The longest time out is 60 minutes of no input then it will automatically turn off. Neither the IOS app nor the Android app for LS50W can wake up the speakers. Obviously, you can use the remote to turn it on. As a workaround I used a Logitech Smart Hub (with built-in IR blaster). Then I use the Logitech harmony app from my phone to turn on the LS50W. With the Smart Hub, you can also link it to Alexa/Echo then you can use voice input to turn on LS50W.
