Siblings in Dynaudio's Focus series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Dynaudio Focus 20 XD digs deeper - 39Hz against 43Hz. A subwoofer would even that out. |
| Built-in power | A | Dynaudio Focus 10 has the bigger amplifier (390W vs 300W RMS). |
| Connections | A | Dynaudio Focus 10 adds Wi-Fi and streaming. |
| Size | depends | Dynaudio Focus 10 is easier to place; Dynaudio Focus 20 XD is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | A | Dynaudio Focus 10: a sub output. |
| Price | evenly matched | Much the same money ($5,500 vs $6,000 a pair). |
A Dynaudio Focus 10 B Dynaudio Focus 20 XD
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?
Dynaudio Focus 10 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. In a large or open-plan room, Dynaudio Focus 20 XD has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Dynaudio Focus 10 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.
