Siblings in KEF's LS series, so they share a family sound. It comes down to size, output and price.

| Built-in power | evenly matched | Similar onboard amplification (230W vs 200W RMS). |
| Connections | B | KEF LSX II LT adds HDMI. |
| Size | depends | KEF LSX II LT is easier to place; KEF LS50 Wireless is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | KEF LS50 Wireless: a sub output; KEF LSX II LT: a sub output. |
| Price | B | KEF LSX II LT is cheaper - $999 against $2,200, about 55% less; arguably a different class. |

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 LSX II LT is the easier recommendation: it leads on most of the measured areas and costs less. Take KEF LS50 Wireless if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 79Hz anyway, so judge these on the other rows instead. In a large or open-plan room, KEF LS50 Wireless has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF LSX II LT is the easier speaker to get right.
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.
