A generation apart: Dynaudio Focus 30 is the newer design, against a 2016 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (29Hz vs 30Hz). |
| Built-in power | B | Dynaudio Focus 30 has the bigger amplifier (670W vs 450W RMS). |
| Connections | B | Dynaudio Focus 30 adds Bluetooth, Wi-Fi, streaming and digital inputs. |
| Size | depends | Dynaudio Focus 30 is easier to place; Dynaudio Focus 30 XD is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Ported vs Sealed. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability | B | Dynaudio Focus 30: a sub output. Dynaudio Focus 30 sits in a wider range (4 models), so a matched surround system is easier later. |
| Price | evenly matched | Much the same money ($8,250 vs $8,250 a pair). |
A Dynaudio Focus 30 XD B Dynaudio Focus 30
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 30 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 30 XD has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Dynaudio Focus 30 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.
