Short answer: the Dali Rubikore 6 for better sound quality, the Atlantic Technology 8600eLR for the lower price. The Dali Rubikore 6 ranks #64 of 71 floorstanding speakers at $8000. The Atlantic Technology 8600eLR ranks #65 at $5700, $2300 cheaper.
What the Atlantic Technology 8600eLR offers: 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 4.53 with a subwoofer. Watch for: The raw preference score is only 1.92, 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.
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 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. 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 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.
Buy the Atlantic Technology 8600eLR if the price matters more than sound quality. Buy the Dali Rubikore 6 if sound quality matters more than the price.
If sound quality matters at all to you, skip both of these and look higher up the 71 floorstanding speakers instead.
