#54 Dali Rubikore 6: $8000 Safeandsoundhq eBay
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.
How it compares: Just above it: Magnepan LRS+ - $6700 cheaper, 1.3Hz lower bass extension (-3dB). Just below it: Endow Audio Bravura 7 - $6000 more, 5.4Hz lower bass extension (-3dB).
