Review on KEF LSX Wireless Music System (White by Amar Amar ᠌

Revainrating 4 out of 5

Good product, more pros than cons.

The task was to install a system that meets the following requirements: 1. Hi-Fi shelf speaker. 2. Ability to play FLAC. 3. Support AirPlay 2 4. Toslink interface Since the speakers were supposed to be placed on the side of the TV, I did not fence the garden with a WiFi connection, all the wires were left behind the TV. Both the speakers are connected to the Internet and to each other by a twisted pair cable, although it could be done over the air. From the TV - optics. The kit comes with a category 6 patch cord for connecting the main and slave speakers to each other. The color indication of the signal source on the body of the main speaker seems strange at first, but you get used to it very quickly, it's convenient. If annoying, then you can turn off the indication through the application. I stream FLAC from a DLNA server based on minidlna, it works like clockwork, the sound is amazing. The sound from other sources is good, but nothing more. The phase inverter works from the heart, there are basses. In a good way, you need to add a subwoofer, it will be even more fun. I won’t tell you anything interesting about AirPlay, it just works silently. If optical sound is enabled, then when AirPlay is activated on the phone, the speakers automatically switch to a new source. In the opposite direction, you need to switch with the remote control or from the application. The speakers are excellent, the functionality is completely satisfied. The volume control on the TV is certainly frustrating, but it's not something I'd be looking at other options for.

Pros
  • 1. Sound quality. 2. Compactness. 3. A sufficient number of input interfaces. 4. Possibility to invert column orientation (left/right), as it may be convenient to connect different wires on one side of the same TV, but not on the other. By default, the main column is located on the right, so you can place it on the left and, by setting the inversion, let the software know about it.
Cons
  • Of the serious, perhaps, only the volume control: 1. There is a real lack of a digital indicator of the current volume level before the signal is applied to the input. The only place where you can see the volume level is the application on the phone. Opening it before turning on the TV is, to put it mildly, stupid. But otherwise, you can be notably scared of the volume. 2. Sound control from the native remote control is terribly slow. From zero to maximum, as well as in the opposite direction, go offhand for half a minute. 3. On the 2022 LG TV, I set up the speakers as a soundbar connected via optics, to be controlled via a universal remote control. Speaker on/off works fine. The volume control works, but, like from the native remote control, it is terribly slow and plus you can’t see the volume level on the TV, they just blink + and -. LG has LG Sound Sync technology to sync TV volume levels via Toslink, but this is unfortunately not supported by KEF. Alternatively, you can connect your TV via Bluetooth, but I'll still experiment. When streaming via AirPlay, Flac or Bluetooth, the volume can be controlled from the phone (natively or from the application), so this unpleasant feature is only applicable when working with a TV, which is obviously not the main mode of operation for this kit. The need to have two applications on the phone (one for control, the second for streaming control) is not a drawback of course, but very strange.
