Short answer: the Revel F226Be. It ranks #9 of 54 floorstanding speakers by sound quality at $7700; the Dali Rubikore 6 ranks #49 and costs $8000, so there is not much of a tradeoff to weigh.
What the Revel F226Be offers: Compact three-way tower with a beryllium dome tweeter in an acoustic lens waveguide, a dedicated 5.25” mid-range, and dual 6.5” woofers (not a coaxial layout) - all Deep Ceramic Composite aluminum cones engineered specifically to… Watch for: Minimum impedance dips to about 3.7-4 ohms below roughly 500Hz despite the 8-ohm nominal rating, so it wants a genuine 4-ohm-capable two-channel amplifier; budget AVRs rated only for 6 or 8 ohms may struggle.
What the Dali Rubikore 6 offers: 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… Watch for: 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…
Buy the Revel F226Be. It ranks higher for sound quality than the Dali Rubikore 6 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Dali Rubikore 6. It ranks near the bottom of the 54 floorstanding speakers, so look higher up the list instead.

The Two Speakers In Full
Revel F226Be: $7700 Crutchfield
Pros: Compact three-way tower with a beryllium dome tweeter in an acoustic lens waveguide, a dedicated 5.25” mid-range, and dual 6.5” woofers (not a coaxial layout) - all Deep Ceramic Composite aluminum cones engineered specifically to avoid breakup outside their crossover bands, and it measures that way: neither the woofers nor the mid-range show breakup spikes even well outside their intended pass bands, and even the front port measures unusually clean (only a mild ~3dB bump around 150Hz, well controlled versus the resonances the reviewer typically sees from ports). On-axis frequency response holds within about ±1.5dB above roughly 65Hz - excellent linearity - and off-axis behavior tracks it closely, with only mild, subdued peaking around 4-6kHz that doesn’t show up as real resonance in the spinorama data. Average sensitivity around 90dB (2.83V/1m), notably higher than some competing three-way designs and most bookshelf speakers, translating directly into better dynamic range at both low and high listening levels - one reviewer specifically praised its ability to deliver full transient impact (snare hits, kick drum) even at quiet, conversational volumes rather than needing to be cranked up to feel dynamic. Wide, consistent horizontal radiation of about ±60-70° at the -6dB point, landing right in the reviewer’s preferred range for an enveloping soundstage without excess diffusion, and exceptionally wide vertical dispersion - roughly ±80° up to 10kHz and still ±70° above that, which one reviewer called the widest vertical radiation pattern he had measured to date. Distortion stays under 3% even at 104dB SPL, and in real-world testing up to 105dB from 12-14 feet away, full-range with no crossover, the reviewer heard no audible mechanical noise, port chuffing, or compression at all. Flat enough on- and off-axis response that toeing the speaker 10-15° away from the listener preserves the same tonal balance rather than changing it, and the wide, well-controlled directivity lets sidewall reflections reinforce rather than smear the soundstage.
Cons: Minimum impedance dips to about 3.7-4 ohms below roughly 500Hz despite the 8-ohm nominal rating, so it wants a genuine 4-ohm-capable two-channel amplifier; budget AVRs rated only for 6 or 8 ohms may struggle. F3 of 56Hz and F10 of 36Hz mean it doesn’t extend nearly as low as some three-way rivals with larger woofers - a dedicated subwoofer (10-12”, or 15” for content below 30Hz) is recommended for home theater or bass-heavy music, even though the speaker itself can play surprisingly loud without one. Vertical directivity tolerance is tighter in the crossover handoff region than a true coaxial design would offer, since the tweeter, midrange, and woofers are physically separated - a mild directivity bump appears around 2-2.5kHz that’s typical of non-coaxial multi-way speakers, though not audibly problematic within about ±10° vertically. On-axis, the top end reads as a bit bright according to one reviewer’s subjective impression, generally benefiting from some toe-out. High-gloss cabinet finish can create distracting reflections if used behind a projector screen in a home theater setup. Front-ported, so it can technically sit close to a wall, but doing so makes the bass boomier.

Dali Rubikore 6: $8000 Safeandsoundhq
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.
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.
