Siblings in Dynaudio's Focus series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | Dynaudio Focus 50 digs deeper - 22Hz against 30Hz. A subwoofer would even that out. |
| Built-in power | evenly matched | Similar onboard amplification (670W vs 670W RMS). |
| Connections | evenly matched | The same set of inputs and streaming options. |
| Size | depends | Dynaudio Focus 30 is easier to place; Dynaudio Focus 50 is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | depends | Dynaudio Focus 50: a sub output; Dynaudio Focus 30: a sub output. |
| Price | B | Dynaudio Focus 30 is cheaper - $8,250 against $11,000, about 25% less. |
A Dynaudio Focus 50 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 50 is ahead, but only on 1 of the measured areas, and it costs about 33% more. That is a lot of money for a narrow margin on paper - Dynaudio Focus 30 looks like the sensible buy unless something else about the Dynaudio Focus 50 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 30Hz anyway, which makes the cheaper Dynaudio Focus 30 much easier to justify. In a large or open-plan room, Dynaudio Focus 50 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.
