Siblings in KEF's LS series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | KEF LS LUXE digs deeper - 42Hz against 45Hz. A subwoofer would even that out. |
| Built-in power | evenly matched | Similar onboard amplification (380W vs 380W RMS). |
| Connections | B | KEF LS50 Wireless II adds Bluetooth, Wi-Fi, streaming and digital inputs. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | B | KEF LS50 Wireless II: a sub output. |
| Price | B | KEF LS50 Wireless II is cheaper - $2,999 against $4,000, about 25% less. |

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
KEF LS50 Wireless II has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. Think about the whole system, not just the speakers: the roughly $1,001 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
