These sit in different price classes - Dynaudio Focus 10 costs roughly 1.8x what KEF LS50 Wireless II 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 (43Hz vs 45Hz). |
| Built-in power | evenly matched | Similar onboard amplification (390W vs 380W RMS). |
| Connections | B | KEF LS50 Wireless II adds HDMI. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Dynaudio Focus 10: a sub output; KEF LS50 Wireless II: a sub output. KEF LS50 Wireless II sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | KEF LS50 Wireless II is cheaper - $2,999 against $5,500, about 45% 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 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 $2,501 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.
