For instance , if you ran Tidal/Roon to it in a WIRED configuration you could get around a lot of these functionality issues. But that would add another $1000 for a Roon Core device and subscription. And require a local Ethernet connection which I lack (and can’t add). But kinda defeats the purpose of wireless doesn’t it?

So I’m going back to my 20 plus year old Meridian DSP’s fed by a Bluesound Node 2 which doesn’t have nearly as many issues while they iron out the kinks, improve the App, add MQA, and come out with an all matte black edition. It has phenomenal potential. And for those that have workarounds for all these faults, there is nothing better at the price. I’ll be back. When they’re ready for prime time. Maybe sooner when someone points out what I’m missing...
Have you not tried using the Node 2 as the sole input to the LS50 Wireless? It can run your playback absolutely gapless, handle MQA flawlessly, and act as a Roon endpoint.

Office: NAD M10, KEF LS50, KEF Kube 10b, Pro-Ject RPM1 TT w/ Ortofon 2M Red. Guest room: Hafler 300 L-R, KEF Reference Model 100 center, KEF iQ10 surrounds, modded M&K V-90 sub, Bluesound Vault 2.

Not the OP but that does seem like a very popular combination on the Roon forum.
I don't know where the idea that you need a $1000 + device for Roon Core comes from. Any PC or Mac can run it, some NAS devices, or you can buy an Intel Nuc for $400. I just let it run from my Mac while using it for other things.
Not exactly breaking the bank there and Roon is really great.
A Logitech harmony remote can be had for $29.
The Kef/Roon combination uses the WiFi connection.

Angry LS50 Wireless speakers dead after 18 months!

Today, my Kef LS50 Wireless speakers made a very loud crack noise, the UPS on my NAS indicated a power variation and the speakers are now DEAD. I purchased them in April 2017, so they are only 18 months old. Scanning the Internet, the symptoms indicate that the power supply board has failed on the right speaker.

Very good speakers but as a 40-year user of Kef speakers, this is a bit disappointing, and I expected better.

Hopefully, they will be repaired under warranty?

Warranty in the U.S. is a miserly year so hopefully you are in the UK or a country with actual consumer protections.

i bought a pair around the same time, and sent them in for repair about a month ago. they said the problem (static coming from the left speaker) was in the amp boards, replaced them, and sent them back. all i had to pay for was shipping to the US home office, as ls50w cannot be repaired by local techs.

If you bought your speakers with a credit card, they may have an extended warranty clause. My credit card extends the manufacturers' warranty 1 year automatically.

Has anyone heard or are interested in the Elac Navis? They're basically a competitor to the LS50W but they've got little buzz. I haven't seen coverage outside of one Youtube reviewer below. Meanwhile the KEF LSX, which came out around the same time, has already been reviewed by many audio sites.

Trying to find answers to this, but what do you guys have the Windows volume set as vs the LS50W's? Do you have windows at 100% and control using the KEF volume control, or do you have the LS50W's set at 100% and control using windows volume?

I prefer to let the source device control the volume, be it my phone, computer, etc. I don't have the LS50W set to 100%, but have it relatively high up, and use the volume control on the source device.

In general you should use keep the digital source at 100% and use the end volume control. Attenuating the digital source and then amplifying will or might add quantization errors/noise and lower the signal to noise ratio.

That’s what I’ve been doing, setting the windows volume at 100% and adjusting the volume of the LS50W’s using the remote, which I find very convenient.

I connected an old KEF PSW4000 sub to it, but I’m not sure what settings to use. Do you guys use the KEF app to change the low pass or high pass and stuff? Or you just plug the sub in and forget about it. I listen to a lot of EDM and do value a good quality rumble.

I've had the Navis in my house for a few hours and I'm doing A/B listening with the LS50W. I will keep the one I like best. I haven't had much time with the Navis but it's very promising so far!

according to kef (I emailed them on this)
turn up sub to 75-100%volume (same with cross over, all the way to the right)
and let the kef apps (basic/expert) dial it all in from there

Q: Right cable for Aux connection?

I have an Oppo 103 player. I originally ran HDMI to TV, then optical to LS50W. Worked. I removed the optical and connected RCA cable from LF/RF analog outs on Oppo to Aux input on LS50W (and changed Kef input to <Aux>). I get video but no audio. Tried blu-rays, DVDs, CDs, and Tidal (on Oppo).

I followed Oppo manual re: settings (and I've asked for help on that thread). For this audience I'm asking if the cable, "Blue Jeans Cable Ten White Speaker Cable, with Welded Locking Bananas", is the right cable type for the KEFs? Thinking I might have a cable problem.

In part, I ask because even with locking color fully unlocked it is a very tight fit into the posts on the KEF, with ~ 1/2 remaining outside of the post.

Appreciate any help. Bit of a noob.

How can you use speaker wire with banana plugs on the KEF LS50 Wireless speakers if they don't have speaker binding posts? Are you trying to put them into the RCA aux inputs?

Ken - Thanks. Yes, I have the Blue Jeans cable into the AUX inputs on the LS50Ws. Is the problem that I'm using wrong cable? Again, I'm bit of a noob in this area and the KEF documentation is limited. Thanks.

You are trying to plug banana plugs/speaker wire into an RCA ins/outs?

You need to be using a shielded cable with RCA jacks like this.

William (and Ken) - Thanks! I'm a moron. Don't know how I put myself down the path of thinking speaker wire was the way to go. I'll go the shielded RCA route. Hopefully, I at least provided fodder for the bar...."this one moron was trying to......"

Tell us what you think when you get a chance. Would be curious. Also, the Dynaudio Xeo 20 is well regarded and is a direct competitor to the LS50W but have not seen much discussion on it either.

I’ve had the XEO 3 in the past and thought they were nice. I’m considering a pai of KEF LSX now for the bedroom or a Naim MUSO. That said I think the Dyn and KEF sound are different with the KEF being a bit more forward sounding compared to the Dyns.

You have to have also bought Bose Acoustimass for that. Buying quality speakers like the LS50W's gives you a pass.

No worries, we all had to start somewhere. Like William said, you had the smarts to get high quality speakers, so don't beat yourself up and no one else will. Educate yourself.

Ken and William - Thanks again for the help and for being nice about it, diplomatic. It's all working now, sounds great.

The research I did here and elsewhere led me to the KEFs so I'm happy about that but, yes, I still have a lot to learn. In full transparency I did buy Bose 501s back in '85 . Loved them at the time but it was my first and last Bose purchase.

I managed to listen to a pair of Navis ARB-51 and it does sound great, pretty comparable to the LS50W to me. It is a little more flat overall so it is all about preferences. I tested them at comfortable "you can still hear people talk" levels, not ear piercing.

Also, I updated the LS50W firmware and it was a pain. Turns out I had to physically connect to the router using Ethernet for the computer to find it, not wifi. Their update tool doesn't mention this. I'm glad my router wasn't in a different room.

Had the LS50W right when it first came out and even though it sodas great there were lots of issues for the first year or so.
The software was garbage and so was the firmware. They finally got it somewhat stable about 8 months in. I had to send mine back twice, at my expense to get replacements. They are heavy so that wasn't cheap. I finally sold them because they were going to be out of warranty and I didn't want them out of warrant.
They need to come out with a version 2 with all the original issues fixed and add airplay 2 plus updated the software. But I see the LSX requires two apps, one just for setup, so it doesn't sound like they have advanced much.
Maybe Elac has better developers for the Narvis instead of whatever 3rd world cheap developers Kef has been using.

They are heavy so that wasn't cheap. I finally sold them because they were going to be out of warranty and I didn't want them out of warrant.
They need to come out with a version 2 with all the original issues fixed and add airplay 2 plus updated the software. But I see the LSX requires two apps, one just for setup, so it doesn't sound like they have advanced much.
Maybe Elac has better developers for the Narvis instead of whatever 3rd world cheap developers Kef has been using.
The Navis doesn't have all the electronics of the LS50W, just an amp and wireless module. No DAC, DSP, Bluetooth, no firmware. Seems closer to a studio monitor in many ways. The Navis and LS50W are similar but I think target slightly different audiences. It really depends on your priorities.

There's still plenty of opportunity for KEF to continue improving the apps and firmware on LS50 Wireless, and they probably will. I think the move to two separate apps was the right one.. This way, you can have the setup app on your mobile device yet not prominently on its main screen, right where you would put the app for running them. It also makes each app a little less complicated. I have other apps that work this way and I prefer it.

KEF R500, R200C, R100, R50, SVS SB2000 sub, NAD T758v3 AVR, LG UP875 4K BlueRay, Samsung UN55JU6500F 4K LED TV, KEF M500 headphones, Sony CDP-CE500 CD changer. Office: NAD M10, KEF LS50, KEF Kube 10b, Pro-Ject RPM1 TT w/ Ortofon 2M Red. Guest room: Hafler 300 L-R, KEF Reference Model 100 center, KEF iQ10 surrounds, modded M&K V-90 sub, Bluesound Vault 2.

What is the likelyhood that KEF will do an update on the LS50W? Does KEF tend to do MKII, MKIII versions of their speakers? The LS50W is sort of a follow up to the KEF X300A. Aside from quality control stuff, there are things they could update such as have a wireless option like the LSX. They could also update to Bluetooth AptX HD. And since some people have complained that their usb interface isn't great, they could maybe integrate a filter or something. I would personally like physical on/off button and volume knob. I'm sure they can continue to improve the internal dsp some more too.
