Short answer: the AsciLab C6B. It ranks #6 of 203 bookshelf speakers by sound quality, rated 4.7/5, at $1,145. The ELAC DBR62 ranks #77, rated 4.0/5, at $678.97, $466.03 cheaper, which does not close the gap in sound quality.
What the ELAC DBR62 does well: Two-way design with a 6.5” woofer and 1” dome tweeter in a shallow waveguide, with the tweeter positioned close to the woofer for near-point-source coherence: giving more vertical listening leeway than typical two-ways. Watch for: A slight recess in the 1-2kHz region reduces vocal presence somewhat compared to other speakers in direct comparison.
The AsciLab C6B is the more accurate option. Two-way design pairing a 1” aluminum ceramic dome tweeter on a large waveguide with a 6” aluminum ceramic cone woofer, crossed over at 1.1kHz, plus a rear passive radiator. Its measured preference score, a predictor of how neutral it sounds, is 6.33 against 5.07 for the ELAC DBR62. The tradeoff: Bass rolls off around 50Hz in-room (F3 54Hz, F10 35Hz), so a subwoofer is needed for real extension below that.
Buy the AsciLab C6B. It is rated higher for sound quality, and saving $466.03 with the ELAC DBR62 does not make up for the sound-quality gap.

The Two Speakers In Full
ELAC DBR62: $678.97 per pair Amazon Crutchfield eBay
Same family: the ELAC Debut Reference DFR52 (floorstanding, estimated 4.3/5) and the ELAC Debut Reference DCR52 (center, estimated 3.4/5).
Pros: Two-way design with a 6.5” woofer and 1” dome tweeter in a shallow waveguide, with the tweeter positioned close to the woofer for near-point-source coherence: giving more vertical listening leeway than typical two-ways. Notably forgiving of placement and aiming: sounds good from directly on-axis all the way to 30° of toe-out (parallel with the rear wall), making it more room-independent than many speakers this price. Wide horizontal radiation of about ±70° until the tweeter starts beaming, right in the reviewer’s preferred sweet spot. A mild, wide-Q bass bump centered around 100Hz adds a bit of extra punch that the reviewer personally likes. On-axis linearity within about ±2.5dB, with a strong measured preference score of 5.3. Distortion stays below 3% at both 86dB and 96dB until around 50Hz. Vertical sweet spot of about ±10-20° works well for multi-row home theater seating. The reviewer calls it “the epitome of a good speaker” for its price, with no reservations recommending it. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.3dB.
Cons: A slight recess in the 1-2kHz region reduces vocal presence somewhat compared to other speakers in direct comparison. A mild hot spot around 4-5kHz can read as slight sibilance when pointed directly on-axis. Low-to-mid sensitivity (about 84.3dB) combined with a current draw that behaves like roughly 2.4 ohms between 100-200Hz means it’s best driven by a dedicated 4-ohm-capable amplifier rather than an AVR. A diffraction dip from the baffle edge is visible in measurements: typical of any standard rectangular-baffle speaker and not correctable without a much more expensive curved-baffle design. Multitone distortion testing suggests some potential midrange distortion could be audible on certain material, though the reviewer didn’t personally notice it. Minor resonances appear around 700Hz and 1-1.5kHz, possibly tied to the enclosure, port, or cone/surround edge termination, though their audible impact appears minimal. F3 of 53Hz means a subwoofer is still needed for real bass extension below about 40Hz.

AsciLab C6B: $1145 per pair Ascilab eBay
Same family: the AsciLab C5B (smaller bookshelf, rated 4.2/5).
Pros: Two-way design pairing a 1” aluminum ceramic dome tweeter on a large waveguide with a 6” aluminum ceramic cone woofer, crossed over at 1.1kHz, plus a rear passive radiator. Unusual trait: horizontal radiation actually widens at higher frequencies instead of narrowing like most two-way designs, which keeps image focus and soundstage depth consistent whether you toe the speakers in or out (5-10° off-axis was the sweet spot in testing). Vertical radiation also stays wide straight through the 2kHz crossover region, so the sound doesn’t collapse when standing up: unusual at this price. CA2034 measurements show strong on-axis linearity, listening window, early reflections, and directivity. Midrange and tweeter distortion stay very low even at 96dB, holding up against a $5,900 Arendal speaker in that regard despite roughly a 5x price gap. At $1145 shipped to the US, the reviewer calls it the best-value bookshelf speaker he’s tested, rivaling speakers 2-5x the price. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 85.6dB.
Cons: Bass rolls off around 50Hz in-room (F3 54Hz, F10 35Hz), so a subwoofer is needed for real extension below that. Low-frequency harmonic distortion increases substantially at 96dB versus 86dB, though it’s second-order and less audible than it looks on paper. Minimum impedance dips to 2.6 ohms (EPDR as low as 1.2 ohms), so it wants an amplifier comfortable driving 4-ohm loads, ideally 100W or more. At 102dB, compression noticeably eats into midrange, bass, and some treble output. Shipping to the US adds roughly $200 on top of AsciLab’s list price. Against the reviewer’s reference Audiofirst Fidelia at a similar price, has slightly less lower-midrange body (about 1dB difference) and a smaller perceived soundstage size.
