Short answer: the DALI Rubikore 6. It ranks #194 of 226 floorstanding speakers by sound quality (rated 3.3/5) at $8,000 and is still sold new; the Atlantic Technology 8600eLR ranks #203 (rated 3.1/5) and is discontinued, so it is only an option used. The Atlantic Technology 8600eLR’s replacement, the Atlantic Technology 8600iLR, is rated 3.2/5 at $6,000.
What the Atlantic Technology 8600eLR does well: A sealed high-output flagship tower with four 8-inch woofers, dual 5.25-inch midranges, 91dB sensitivity and boundary/HF adjustment controls. The tradeoff: The raw preference score is only 2.65, making a subwoofer and correction essential despite the massive cabinet.
The DALI Rubikore 6 is the more accurate, deeper-bass pick. 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. Its measured preference score, a predictor of how neutral it sounds, is 5.27 against 2.65 for the Atlantic Technology 8600eLR. Its bass reaches about 43Hz before falling 3dB, against 68.8Hz for the Atlantic Technology 8600eLR. The catch: 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).
Buy the DALI Rubikore 6. It is rated higher for sound quality and still sold new, while the Atlantic Technology 8600eLR is discontinued.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.

Newer model: the Atlantic Technology 8600iLR, ranked higher, estimated 3.2/5, released Mar 2024. See every Atlantic Technology 8600 generation.
Same family: the Atlantic Technology 8600eC (center, rated 3.3/5).
Pros: A sealed high-output flagship tower with four 8-inch woofers, dual 5.25-inch midranges, 91dB sensitivity and boundary/HF adjustment controls. The local snapshot measures 58Hz extension and scores 5.26 with a subwoofer. Measured bass extension of 68.8Hz (-3dB).
Cons: The raw preference score is only 2.65, making a subwoofer and correction essential despite the massive cabinet. Each tower weighs over 90 pounds, and value is weak if two-channel neutrality is the main goal. Discontinued.

DALI Rubikore 6: $8000 per pair Safe and Sound HQ $8000 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.
