No single best speaker here - they are built to different priorities, and the right one depends on your room, your sources and what you listen to.

|---|
| Bass | B | Buchardt A700 digs deeper - 17Hz against 30Hz. |
| Built-in power | evenly matched | Similar onboard amplification (670W vs 600W RMS). |
| Connections | A | Dynaudio Focus 30 adds Bluetooth, streaming and digital inputs. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | A | Dynaudio Focus 30: a sub output. |
| Price | B | Buchardt A700 is cheaper - $6,600 against $8,250, about 20% less. |
A Dynaudio Focus 30 B Buchardt A700
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: Dynaudio Focus 30 measures better, Buchardt A700 costs about about 25% more% 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. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 30Hz anyway, so judge these on the other rows instead.
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.
