Performance
Sound Quality
The sound quality on the KEF LSX Wireless Speakers (SP3994JX) is absolutely amazing. The bass is deep and rich, the mids are crisp and clear, and the highs sound like they’re right in front of you.
The LSX speaker features KEF’s Uni-Q technology, resulting in superb stereo imaging. The high frequency driver sits at the center of a midrange and bass cone, giving you clearer music across an expansive listening area.
With two speakers, sound is richer and more realistic. You can hear the music in its full detail because it is played back with actual depth as well an accurate sense of where instruments were placed on the stage. You’ll know where every instrument is coming from and feel like they’re actually in your living room.
No matter what genre of music you listen to or if there’s a lot going on in a scene from your favorite movie, these speakers will not disappoint. They truly live up to their performance promises!
Volume
The KEF LSX Wireless Speaker can fill a medium-sized room with high-quality sound without an ounce of distortion.
The 102 dB maximum output is not enough to tear down the walls of your house, but it’s more than enough to make you feel the music on a physical level. And that’s true even without pushing the speakers to their max volume.

KEF claims “The LSX wireless speaker is a full-range system that doesn’t compromise in any area of sound reproduction.” and we can confirm this statement! The bass has the perfect amount to provide warmth without taking over, while other frequencies are crisp and clear. This makes it easy to enjoy music at lower volumes or crank up your favorite song for dancing around the house with no distortion (and they’re not just great for music!)
You will be able to experience every detail from all types of movies or television shows thanks to these speakers’ immersive quality. They have commendable power handling capabilities which make them ideal for larger spaces such as living rooms or outdoor patios during summer BBQs!
Connectivity
Sound quality is important, but who wants to look at those ugly wires all the time? With no need for a cable, you can position these speakers wherever you like and connect over your home WiFi network.
These speakers also support AirPlay 2 and Bluetooth, and are compatible with most soundbars and surround sound systems for the ultimate home theater experience.
Note, however, that a lack of USB and RCA inputs may be problematic if you intend to hook these up directly to a laptop or older audio equipment.
Also, some users have reported issues with using the KEF app to connect to a device. This is something that the company can hopefully fix in time.

Design
The LSX’s design is a perfect balance of form and function. Product designer Michael Young has carefully considered details include port accent colors, as well as a color-changing LED to subtly indicate which source you’re tuned into.
There’s no arguing that these are some of the most attractive speakers on the market.
Alternatives
Sonos Five
The Sonos Five is a worthy contender to the KEF LSX speaker and comes in at almost half the price.
They’re both wireless speakers with excellent sound quality and they each have their own app for controlling them separately or as part of a Sonos home audio system.
KEF LS50 Meta
The KEF LS50 Meta present an upgrade from the LSX in terms of sound quality, but the price point is significantly higher.
Like the LSX, these speakers feature the Uni-Q array, an innovative speaker design which produces amazing sound quality. With 12th generation of this technology and MAT (Maximum Amplitude Technology), you can expect a clearer and more life-like experience with reduced colouration or distortion than ever before possible.
