KEF LS60 Wireless Just Announced

[Vacceo]

Yes the bass management could be improved upon .

I think the software in the kef speakers could potentially have this and PEQ and room correction.

I think they underestimate customers a bit , they eq features they have like wall mode and such avoids all talk about frequency and other “complicated” matters , even thier subs has generic wall and corner settings.

They sacrifice some performance to get ease of use ? Just hide the complexity in some hidden expert mode us nerd can use

If the Music Integrity Engine (the name KEF has given to their DSP implementation) supports it, on top of the extra options, I´d add Dirac support if the hardware can take it. It´s not that strange considering Dynaudio actives have it availeable.

I think many prospective and already owners would like their KEF LS60 be Dirac enabled, just like the active speakers from Dynaudio. Of course, based on a separately purchased license.

Absolutely! Plus any user could choose how far they want to push it; from limited bandwidth all the way to DLBC multisub or eventually, ART.

Probably due to the speakers being actives, the fine tunning could be quite interesting.

Since a few months my LS60’s stutter when playing through Spotify Connect. It is fixed for a few days by rebooting the speakers/making them powerless. Anyone who has this problem? They are connected through wifi.

What device are you using to launch Spotify Connect. A tablet, phone or computer?

An iPhone. But after some more reading; more people has dropping wifi speeds. After a few days the network speed dropt to about 3mbps. After I reconnect the speakers the speed is op to 40mbps. It's at 5ghz and 2,4ghz.

With my LS60s, I noticed that I did not have any issues when streaming from my NAS or launching Tidal Connect from my computer. When I launched Tidal Connect from my tablet, though, I had issues. Weird because once the LS60s start streaming they should be receiving the stream straight from Tidal.

Anyway, see my posts here:

Progress made. I enabled access to "Developer options" on my tablet. In there, I went to "Background process limit" and set it to "No background processes". CPU utilization is staying pretty constant at 14% while streaming. There are some increases in utilization and clock speed, but overall...

Those changes solved the problem for me. Your mileage may vary.

Some general Q about Kef software that would be interesting to know .

The phase compensation in for example ls60 adds approximately 4.5ms latency , are the subwoofer outputs compensated for this ?

The Kef speakers have subwoofer settings that includes presets for their own subs like kf92 is this more than just ready made crossover frequency suggestions ? Is for example the latency of the sub included in the preset ?

Hi Mnyb,

The phase compensation corrects for the frequency dependent phase delay. This means that when phase correction is switched on, the mids and highs are delayed back to the LF. When seen from the subwoofers point of view, the phase delay of the LS60 LF is the same (roughly) with phase correction on vs off. Therefore no subwoofer delay compensation is required.

The subwoofer presets in the KEF connect app are presets for the user accessible controls, so yes, they are only crossover and gain settings.

Gain ? Do you also provide info for the corresponding gain settings on the for example kf92 to match this ?

Btw this is very helpful for not so nerdy folks wo the means to measure this

The gain in the app is controlled by selecting the relevant preset. The gain of the subwoofer depends on the model, but we tend to use clock face descriptors (12 O'Clock, 3 O'Clock etc.), along with a picture of what the volume knob should be set to.

Some images of the process can be seen at: https://assets.kef.com/documents/ls50/LS50WII-Subwoofer-Setup.pdf

Although your issue could be due to the same declining wifi speed issue I have observed on 2 different sets of LS60s including mine, Spotify should not need too much bandwidth, at most 1-2Mbps and you should eliminate other potential causes first.

Use 5ghz wifi only for your LS60, you can do this by giving the 2.4ghz a different SSID name so your LS60 will only stay on 5ghz. 2.4ghz is slower and more susceptible to interference vs 5ghz. Also ensure your wifi router/ap is close enough to the speakers ideally with direct line of sight (not passing through walls) to give it a strong 5ghz signal.

For those with the LS60, how’s the touch screen interface?
On my LS50WII, I had to disable the touch screen on the speaker so that it doesn’t randomly shutting down and switch sources. I contacted KEF about this and their best solution is to for you to disable the touch screen. Disappointing.
I have a lot of KEF speakers from LS50 to R series to Blade. Love the sound but not really trusting their electronics at this point.

The LS60 doesn't have one.

That was my early experience with the original Ls50W. It did eventually even out with upgrades, but the original ship was awful.

But I used almost exclusively Roon and optical (TV) later on.

There is no touch screen on the 60’s as such not like the LS50’s , there iis the ‘connect’ app of course and the remote.
I haven’t experience that issue with my LS50’s wireless I hope the issue is sorted now.

More question . anyone integrated a subwoofer with your LS60 any hint to success ?

The speakers don't have any obvious delay/latency settings ( but it actually has *)

SUB's with DSP and processing can have quite varying latency ( delay from input to output , i takes som time to process stuff ) internet search gives that the latency for Kef*s own sub like the KF92 are around 0,4ms and hypex plate amps are similar some subs use those this is not much, and manageable.

But other sub's like Arendal has 8ms of latency ? what to do then ?

If you have some AVR/processor etc you make this work no problem , but we are on the topic of connecting a sub directly to LS60 .

*) Kef has wireless extender kit for subwoofers named kw-1, and active kef speakers has a setting for if you use this device , this device has a latency of 17ms !! so obviously there is latency correction but not accessible for other purposes ? It would be great if kef exposed this settings for all subs .

So how did you do it ? Used a kef subwoofer close to speaker at similar distance to the listener or other low latency subwoofer ?

 

[terryforsythe]

If I am not mistaken, at least some of the Arendal subwoofers have variable phase control. You can use that to adjust the phase of the subwoofer to align it with the LS60s at the crossover frequency.

That being said, it is not as versatile as using something like a miniDSP. They offer a number of different products that provide a wealth of crossover and EQ options. Just pick the one that suits your needs. That would be a better option in my humble opinion. The downside to that is that you will need to run a cable from the miniDSP to your main LS60. You could use a miniDSP model that includes a built-in streamer, or run a separate streamer.

That’s great about the LS60 not having the touch screen. I might look at a pair and see how they compare to the Blade.
