This is confirming measurements from @John Atkinson: exceptional performance for such a small box, except for high SPL...
Thanks for the link and the excellent discussion, John. But you have to be the first person I know of whose movie watching centers around the kitchen.You can find my measurements of the LSX at https://www.stereophile.com/content/kef-lsx-wireless-loudspeaker-system-measurements
and the in-room response and my auditioning comments using Roon at https://www.stereophile.com/content/kef-lsx-wireless-loudspeaker-system-john-atkinson-june-2019

You can also update the firmware of the speaker. But that does not happen often so that is probably ok.??? I downloaded the app a couple of days ago. How could it be old?
Sorry, my understanding is that the lsx and LS50W use a different KEF app than the LS50W-Meta, which I think is the KEF Connect. It is possible that app is no longer being updated by KEF.??? I downloaded the app a couple of days ago. How could it be old?
with a coaxial driver and 4.5" only I am already surprised the bass -6db point is somewhere at ~57hz already, for desktop/computer speaker use with some wall loading bass boost it should be fully usable and I can imagine very satisfying for such case.As the distortion plots show, this is a low-volume speaker just like the original LS50 is. You can't crank it loud without it severely distorting.

The Fives from Klipsch produce an unbelievably large sound from two little (very nice looking) boxes and toy drivers. I heard them on a recent visit to Harrods, free standing in a huge show room. No aid from walls. - The issue is that they do this with overblown bass and even using EQ can't completely fix this. Still, much fun and perfect for all the family if you want to keep them away from the main system.
The LSX sounds far more balanced and hifi but nowhere near as much fun. It is also lacking in power and grunt compared to the LS50 Wireless (1 or 2).I love the textile covering though.
You can now pick up up a Wireless 1 for a similar price to the LSX. Far better choice imho unless you have a very small room.

If you plan to use these tiny thingies in a large living room and not opt for a sub... you likely value design and decoration over sound, which I suppose us still satisfying
Not sure if you realized, but they actually use a 5.25" midwoofer, not a 4.5"
Do you prefer the sound of the Fives over the LSX?The Fives from Klipsch produce an unbelievably large sound from two little (very nice looking) boxes and toy drivers.

I own both the LSX and LS50w. Highly recommend interested buyers spend more on version 2 just for the new app alone. The app for version one is consistently rated among the worst for android, which for many of us significantly impacts usability and harmoniously living with both systems over the long term.

this is from kef webpage, I am pretty sure it’s a smaller driver than the X300A 5.25” UniQ driver in showrooms
I am pretty sure KEF use outer diameter and won't count the tweeter in their spec sheets, the X300A is spec. with a 130mm (5.25") driver and I just measured mine, it measured 130mm from the surround edge to edge. And IRL the LSX driver does look like a 4.5" not a 5".What's 4.5 + 0.75?

Yea that is really coincidence and misleading, but I would say they are smart not to do so as that likely will cause trouble if they did add the tweeter size in the math and when ppl go do some measurements and sue them for dishonestyI suspected as much, but the correlation was too perfect not to point out!
