Kef lsx wireless music system review năm 2024

For such a diminutive, discreet system of unremarkable power and modest driver dimensions, it summons unlikely low-frequency drive and presence. Bass sounds are deep enough to make the idea of an external subwoofer seem a bit much, and they’re controlled at the attacking edge with proper authority.

Detail levels are high (as they are across the board, to be fair), so there’s plenty of information available regarding texture and tone. The LSX II LT is able to make even minor low-end dynamic variations apparent, and where straightforward punch is concerned they outperform their physical dimensions to a remarkable degree.

The opposite end of the frequency range is equally well served when it comes to detail retrieval, dynamic impetus, and simple fidelity. Treble sounds are bright and ringing, but even if you decide to test the upper limits of the system’s volume they never cross the line into hardness or glassiness. There’s ample bite and crunch should the music demand it, but none of the edginess that less capable loudspeakers can threaten to introduce.

And in between, the KEF creates more than enough space in the midrange for a vocalist to express themselves fully. If there’s information regarding character, technique, or attitude in a recording, there seems little doubt the LSX II LT is ignoring it.

Tonality from the top of the frequency range to the bottom is even and consistent, and there’s sufficient dynamic headroom available to let the quieter moments of a recording contrast nicely with the moments of all-out attack.

The soundstage the system can generate is appreciably wider and taller than the speakers from which it emanates, and it’s organized and controlled with confidence. The relatively complicated driver arrangement demonstrates its worth (again) with a presentation that’s neatly unified and of an appreciable whole.

The LSX II LT proves remarkably tolerant when it comes to lower-resolution content, too. A bog-standard 320-kbps Spotify stream of The Record by Boygenius sounds compressed and compromised, sure, but not to a fatal degree. Some systems can be overtly sniffy about poverty-spec audio files like this, but the KEF is not so judgmental. It does what it can with the information it’s given, attempting to open it up and find the light and shade within it rather than throwing its hands up in despair.

Sizing Up

In performance terms, there’s really only one significant caveat to KEF LSX II LT ownership, and that concerns out-and-out scale. For all the dynamism of its sound and the expansive, organized nature of its soundstage, the KEF can’t muster the sort of outright scale that can fill a larger room with sound.

For the majority of customers, that’s unlikely to be an issue. The LSX II LT is no shrinking violet, after all, and in a typical room-sized room it has no problem with spreading sound all around. Those prospective owners who are hoping to fill a big space with sound from little speakers, though, are advised to think again.

Otherwise, there’s not an awful lot to take issue with. An analog input or two wouldn’t go amiss—after all, if you want to involve your TV in your system, why wouldn’t you want to include, say, a turntable, too? But given what KEF has managed to provide both in terms of sound quality and flexibility with the LSX II LT, I feel a little mean-spirited even bringing it up.

For KEF, the elevator continues to move upwards, even when it’s heading down to what it considers to be the bargain basement.

These sleek bookshelf speakers deliver fantastic, room-filling sound from a small footprint, and setting them up with everything from a TV to your Spotify account couldn't be easier. It’s not easy for a company to top its own greatest hits, but KEF has managed to pull it off once more.

Tasteful Design

The LSX II shares a lot in common with its predecessor, and one of the best things it kept is the same stylish design. Each speaker is a single rounded block, with soft fabric wrapped around the edges. They come in black, white, red, blue, or "Soundwave"—a champagne gold with a wave pattern on the fabric and a striking blue center that came on my review unit.

The whole design hits a sweet spot where it can either disappear into your decor or be a visual focal point of an entertainment system, depending on how you arrange your living space. The color options are a moderate improvement over the previous generation, which were a little less subtle, though the lack of a green option might be a disappointment for those who prefer a nature vibe.

The bottom of each speaker has a ¼-inch mount, which makes it easy to place them on a speaker stand. If you do that, you'll need to be mindful of the power cable that runs to each speaker—and possibly an Ethernet cable, for reasons we'll explain below. But other than that, it's possible to mount the speaker just about anywhere with minimal cable mess.

Myriad Inputs

The beauty of a wireless sound system is how easy it is to connect your audio, and on that front the LSX II have no shortage of options. Once set up, you can cast music over Wi-Fi or Bluetooth, but they also come with a wide range of other, wired inputs for whatever you plan to use them for.

There are typical options like optical and 3.5-mm auxiliary inputs, but new to the LSX II are USB-C and HDMI ARC inputs. HDMI ARC is particularly notable because it makes it much simpler to control a wide array of A/V gear. While testing it, I used it to run game consoles and streaming sticks into my TV, and connected the TV to the LSX II. There was virtually no lag, and once set up I was able to keep using the same volume controls and remotes I'd been using the entire time.

It's worth noting that while connecting a PS5 using HDMI ARC, I was unable to get sound from the LSX II. This was the only device I had this issue with, and I believe this is a bug with the PS5 software, not the LSX II, but it's worth mentioning if you plan to use this with a PS5, as I did.

Is the LSX 50 any good?

The LucidSound LS50X brings wireless audio, excellent battery life, and good sound to Xbox, PC, and Bluetooth devices, albeit at a premium. The LucidSound LS50X is a solid, if a little unremarkable gaming headset.

How good are KEF speakers?

There weren't a ton of competitors on the market, and at the time I felt like KEF nailed the sound, look, and experience. Since then, I've nominated the LSXes multiple times for Golden Ear awards, and I still think they hold up as fantastic streaming speakers with great sound.

Can I use KEF LSX without WiFi?

It is possible to use LSX without a Wi-Fi network? Yes you can. However it is highly recommended you connect the LSX to a home network with a live internet connection, as most of the important features (TIDAL, Spotify Connect) and the KEF Control/Stream apps rely on these.

What is the frequency of KEF LSX wireless?

KEF specifies the LSX's frequency range as 49Hz–47kHz, –6dB depending on the Control settings. The LSX system has four built-in DACs, one per driver, each supporting data sampled up to 24-bit/192kHz, but only with the supplied speaker-to-speaker Ethernet link.
