STEREONET PRODUCT OF THE YEAR AWARDS 2022
- STANDMOUNT SPEAKER (ACTIVE)

“KEF has carved out a strong niche for itself in the past few years with its wireless active designs. It’s easy to see why, as they tick so many boxes and offer easily accessible, high-performance speakers in neat, versatile packaging. LSX II epitomises this, with excellent wireless connectivity, a versatile range of functions, crisp, modern styling and class-leading sound. As with its predecessor, LSX II is the one its rivals want to beat.” - StereoNET, December 2022

I was delighted by their sound, their ease-of-use, and all the important improvements KEF worked into the LSX IIs. If anyone’s looking for a pair of wireless speakers that can do just about anything at a genuinely reasonable price, these should be at the top of the list.” - Mar 2023

Just amazing little speakers!!!!

I came from having Kali monitors, Klispch the fives, and RP 600M. These little Kef are so clear and sound amazingly big for the small size. I paired my LSX II with the Kube 8 MIME to use them as my computer speakers, just amazing full sound. For me, they do not give me fatigue at all. I can listen to them all day long. Money totally worth it. They are even better with the Kef sub.

Simply incredible speakers

If you want a great alternative to a soundbar, or just a great pair of speakers to listen to any music. THESE are the ones. Could not give high enough marks for these. I love HIFI and these are the perfect niche speakers without needing AVR and a ton of wiring.

Smooth & Balanced

I have the LSXIIs on my desk, and I pair them with a sub. I think adding a sub is necessary as they can be a bit anemic with some genres of music.

They are a well-balanced, excellent sounding pair of speakers. I also love the fact that they are Roon Ready, since that is my audio software of choice.

Being that they are active and with the great flexibility to tune the sound to one's preference with the KEF Connect app, you really can’t go wrong with this system.

And, that’s what you’re getting here, a system, and not just a pair of speakers.

Great wireless speakers with some issues.

I got these to work fairly quickly with my updated wireless system. They sound great where I have them placed on top of kitchen cabinets. Their proximity to the ceiling helps the bass which is nice and tight. The app is a bit fussy at times. I have yet to get the auxiliary input to work and my attempts to use the ethernet input failed. In fact, there is no information in the manual or online about using the ethernet input, though some people have gotten it to work.
The speakers stopped working at one point, but resumed working after I pulled the power plug a couple times, causing a reset I think.
I was happy to get a set of reconditioned speakers (by Kef) at a really good price. Given the great sound quality with my setup, I will keep them and enjoy them unless they prove too unreliable. I would like to see Kef make the ethernet input a working one for streaming, since everyone except Kef knows that
a cable connection is more reliable for higher resolution audio file.

BHarmon of Speakers

Their small size belies the quality, depth, and texture of their sound. I paired them with Kef’s Kube 8b sub, immensely enjoyable!
