Short answer: the DALI Rubikore 6. It ranks #195 of 228 floorstanding speakers by sound quality, rated 3.3/5, at $8,000; the Børresen X3 ranks #207, rated 3.0/5, and costs $11,000, which makes this an easy call rather than a real tradeoff.
The DALI Rubikore 6 is the more accurate, deeper-bass choice. Large floorstanding speakers with an unusual four driver layout, low distortion, solid bass and wide dispersion for an enveloping soundstage. Its measured preference score, a predictor of how neutral it sounds, is 5.27 against 2.38 for the Børresen X3. Its bass reaches about 43Hz before falling 3dB, against 50Hz for the Børresen X3. The tradeoff: On-axis, the treble sits 3-5dB above the midrange (especially around 4kHz), giving a sibilant, hot top end that the manufacturer itself recommends compensating for with 30° of toe-out (firing the speakers straight into the room rather than at the listener).
Why pick the Børresen X3: Floorstanding speakers with a ribbon tweeter, very wide dispersion for an expansive soundstage, and a punchy bass that is easy to drive. The tradeoff: A significant midrange suckout centered around 200-300Hz measures 8-11dB below the mean SPL, creating an audible hole in the mid-range that multiple independent listeners also flagged unprompted.
Buy the DALI Rubikore 6. It is rated higher for sound quality than the Børresen X3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Measured Differences
- Bass depth: the Børresen X3 reaches 25 Hz (10 dB down) against 31 Hz for the DALI Rubikore 6, about half an octave deeper. You hear more of the lowest bass notes and kick drums.
- Tonal accuracy above the bass: with a subwoofer taking the low end, the DALI Rubikore 6 scores 7.0 against 3.5 for the Børresen X3 on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
