These sit in different price classes - KEF LS60 Wireless costs roughly 10x what Fluance Ai81 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (30Hz vs 31Hz). |
| Built-in power | B | KEF LS60 Wireless has the bigger amplifier (1400W vs 150W RMS). |
| Connections | B | KEF LS60 Wireless adds Wi-Fi, streaming and HDMI. |
| Size | depends | Fluance Ai81 is easier to place; KEF LS60 Wireless is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Fluance Ai81: a sub output; KEF LS60 Wireless: a sub output. KEF LS60 Wireless sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | A | Fluance Ai81 is cheaper - $499 against $4,999, about 90% 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?
The usual trade-off: KEF LS60 Wireless measures better, Fluance Ai81 costs about about 10x the price% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. In a large or open-plan room, KEF LS60 Wireless has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Fluance Ai81 is the easier speaker to get right. Think about the whole system, not just the speakers: the roughly $4,500 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.
