Short answer: the DALI Rubikore 8. It ranks #193 of 226 floorstanding speakers by sound quality, rated 3.4/5, at $13,000. The DALI Rubikore 6 ranks #194, rated 3.3/5, at $8,000, $5,000 cheaper, which does not close the gap in sound quality.
What the DALI Rubikore 6 does well: Unusual 2.5-plus-half-way, four-driver configuration: two woofers overlap up to 800Hz, then one continues alone to about 2600Hz where the tweeter takes over, followed by a supertweeter engaging at 14kHz. 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).
The case for the DALI Rubikore 8: The flagship Rubikore tower, with three 6.5” wood fiber woofers and DALI’s hybrid tweeter module, a 29mm soft dome plus a 17 x 45mm planar ribbon that extends the treble to 34kHz. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured DALI Rubikore 6, which scored 5.27 on-axis but 4.93 at 30 degrees, so placement and toe-in matter.
Buy the DALI Rubikore 8. It is rated higher for sound quality, and saving $5,000 with the DALI Rubikore 6 does not make up for the sound-quality gap.
Worth knowing: the DALI Rubikore 8 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.0 to 3.7, so treat this verdict as provisional.

DALI Rubikore 6: $8000 per pair Safe and Sound HQ eBay
Same family: the DALI Rubikore 2 (bookshelf, estimated 3.2/5), the DALI Rubikore 8 (larger floorstanding, ranked higher, estimated 3.4/5) and the DALI Rubikore Cinema (center, estimated 3.1/5).
Pros: Unusual 2.5-plus-half-way, four-driver configuration: two woofers overlap up to 800Hz, then one continues alone to about 2600Hz where the tweeter takes over, followed by a supertweeter engaging at 14kHz. A design layout the reviewer says he’d never encountered before. Bass extension reaches a solid 40-45Hz in-room. Distortion is quite low overall, with an especially impressive gap between second- and third-order harmonic distortion in the midwoofers. Wide horizontal radiation of about ±75°, close to the reviewer’s preferred range for an enveloping soundstage. Very good dynamic range, holding up to about 26dB of level increase (70dB to 102dB) with distortion staying within the reviewer’s 3% threshold even at full output. Multiple attractive finish options, including bi-wireable connections. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 86.4dB.
Cons: 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). Even with that toe-out, the midrange still reads as somewhat scooped and recessed: the reviewer needed a wide, +2dB EQ boost around 2.5kHz to bring vocals back into proper balance. A high-Q resonance appears around 590Hz, and another shows up around 800Hz in burst decay measurements. Best combined with sidewall absorption to help tame the elevated 4-5kHz energy, adding to setup complexity. Needs specific listening-height positioning: ears should be at the tweeter (not supertweeter) level for the most accurate sound. Without EQ or acoustic treatment, the reviewer found the combination of a hot tweeter and recessed midrange a “tough sale” despite otherwise strong measured performance.

DALI Rubikore 8: $13,000.00 per pair Estimated Safe and Sound HQ eBay
Same family: the DALI Rubikore 2 (bookshelf, estimated 3.2/5), the DALI Rubikore 6 (smaller floorstanding, ranked lower, rated 3.3/5) and the DALI Rubikore Cinema (center, estimated 3.1/5).
Pros: The flagship Rubikore tower, with three 6.5” wood fiber woofers and DALI’s hybrid tweeter module, a 29mm soft dome plus a 17 x 45mm planar ribbon that extends the treble to 34kHz. Bass reaches 38Hz (±3dB), sensitivity is a high 90.5dB and DALI rates it to 112dB, so it suits large rooms.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured DALI Rubikore 6, which scored 5.27 on-axis but 4.93 at 30 degrees, so placement and toe-in matter. It is a 4 ohm load.
