Whats Included

KEF LSX Hi-Res Wireless Speakers

Q: To get around the WiFi issues.. can I just plug a Chromecast Audio to the Optical input and then cast the Tidal/Quobuz to this Chromecast? Do I lose any lossless audio quality via this hookup?

A: Chromecast Audio will give you 96KHz/24 bit, which is all the speakers will play anyways. They will downsample anything higher.

Q: Since these speakers don't have the USB input like their big brother, the LS50 Wireless, for PC input, is there another way that they could serve as day-to-day speakers for a PC? In other words, is there another way to hook them up to a PC?

A: I hooked them up to my PC via an optical cable.

Q: when will these be available online?

A: undefined

Q: Are these speakers able to be use as rears with a surround system.

A: No - using alone to listen to while on the treadmill

Outstanding speaker with the smarts of a gerbil
I am using these speakers in the near field on a desk. I have them plugged in to one another via the supplied Ethernet cable and am using the optical input direct from my computer as a source. Additionally, I have them plugged in to my network via Ethernet cable as well, although this makes not a bit of difference, but we will get to that. The outstanding: Amazing sound quality. The flaming garbage: Everything else. Set the speakers up? Good luck. Took three tries, which apparently is pretty good. Do you want to stream to the speaker? Airplay and Spotify Connect both decay into unlistenable garbage after a few songs. Crackling, popping; absolutely terrible. I’ve had them wirelessly set up on two different routers, now, and it makes no difference. Apparently hardwiring the speakers doesn’t actually make a difference, as it is still using the wireless connection. Why? I can only assume that the people at KEF who designed this were half drowned and in the process of completing the act. It’s inconceivable why this should be the case. Regarding the noise, I have quite a few Sonos devices in the house and none of them have this issue. Ever. My use case is primarily computer to speaker, so I will rarely run into this being an issue. However, given the price, this is borderline unacceptable. The apps are, in two words, almost useless. KEF Control is fine, I guess. When it detects the speakers it’s fine. If you use two or more devices don’t expect the sound profile to transfer over. I tend to use the remote anyway. The stream app is absolutely useless. Tidal or uh, your local music off a NAS, I guess? Check the App Store ratings, they’ll tell you all you need to know. I purchased a Sonance 10” Subwoofer to go with these, and it’s a monster of a system for my office. This is the gateway drug to great audio. Hard pass on the apps, though. I will likely never buy another KEF active speaker again because of this.

INSANE audio!
INSANE audio upgrade for anyone in the market for “studio speakers”, the audio coming out of these are insanely crisp and clear. Only “con”, if you will, is the startup process... Bit of a hassle, but took me maybe 15-20 minutes, once done I was able to play audio immediately. Adding the 8” sub to these very soon!

Great sound, terrible app integrations
Most of the other reviews here touch on the main points of these speakers, they have a phenomenal sound for their price, and after a nearly painless setup you're good to go. The problems arise when you use the app for these speakers, the KEF Control or KEF Stream apps. Not sure why they decided to split them up, but one acts as a remote and EQ customizer while the other allows for connection to roon, Qobuz, TIDAL, Spotify, etc. My first time opening the app, it said I needed a firmware update. Upon starting it, the app crashed, leaving my speakers unusable. I had to restart the app multiple times to fix the issue, and was only able to resolve it by connecting the speakers to my PC and downloading the firmware manually rather than over wifi. If I have one recommendation for these, use the ethernet connections. Connect them to your router, and connect them together with the included cable. I've read many complaints about the 2.4Ghz signal dropping, and the tedium isn't worth your time. Do yourself a favor, avoid the headache, enjoy the higher bandwidth, and connect them to each other. Once you get past all of the setup, it doesn't take long to recognize the impressive soundstage these produce. 70W for the LF and 30W for the HF, 100W per speaker is wonderful for a near-field listening setup. The Uni-Q drivers are as warm and accurate as ever, with a fast and punchy bass that makes you wonder how the vocals maintain their clarity. Oh, that's right. The tweeter has a separate magnet and stays clean from the mid-driver. I added a B&W 608 Subwoofer to the setup thanks to the sub output on the master speaker, and my bedroom setup feels nearly perfect. Love these speakers. If KEF fixes their app, I'd rate these perfectly at their price point.
