Short answer: the Dynaudio Contour 20i if sound quality matters most, the ELAC Debut 2.0 B6.2 if price matters most. The Dynaudio Contour 20i ranks #96 of 214 bookshelf speakers, rated 3.9/5, at $5,750. The ELAC Debut 2.0 B6.2 ranks #143, rated 3.5/5, at $329, $5,421 cheaper.
The case for the ELAC Debut 2.0 B6.2: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity, holding about ±60° up to roughly 8kHz for consistent stereo width whether aimed directly at the listener or toed out. Watch for: A good size resonant peak around 700Hz stands out from an otherwise smooth response and lingers in cumulative spectral decay (waterfall) measurements: in one reviewer’s sighted A/B test, reducing it by about 5dB via EQ made a noticeable but not dramatic difference.
The Dynaudio Contour 20i is the better-sounding, deeper-bass choice. Two-way design with a 1.125” Esotar2i silk dome tweeter and a 7” magnesium silicate polymer woofer in a vented enclosure. Its bass reaches about 56Hz before falling 3dB, against 64Hz for the ELAC Debut 2.0 B6.2. The catch: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment.
Buy the ELAC Debut 2.0 B6.2 when the price outweighs sound quality for you, and the Dynaudio Contour 20i when sound quality outweighs the price instead.

Newer model: the ELAC Debut 3.0 DB63, ranked higher, rated 4.2/5.
Same family: the ELAC Debut 2.0 B5.2 (smaller bookshelf, rated 3.2/5).
Pros: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity, holding about ±60° up to roughly 8kHz for consistent stereo width whether aimed directly at the listener or toed out. Its larger-than-typical woofer lets it play very loud with minimal distortion, staying under about 1% THD down to 50Hz at 86dB, and minimum impedance stays a comfortable 5-6 ohms. In-room bass extension reaches about 50Hz without much trouble, enough for a solid kick-drum sound. Takes equalization very well: correcting the on-axis response doesn’t cost sensitivity through the midrange, and the underlying directivity behavior (diffraction, vertical mismatch) is mild enough that EQ alone gets most of the way to a well-balanced sound. Vertical tolerance is asymmetric and fairly forgiving: about 10° above the tweeter axis and 20° below it before tonal balance meaningfully shifts. One reviewer called it “a good speaker” with “a good price” rather than just good-for-the-price, and found it fairly neutral overall in-room. Measured bass extension of 64Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: A good size resonant peak around 700Hz stands out from an otherwise smooth response and lingers in cumulative spectral decay (waterfall) measurements: in one reviewer’s sighted A/B test, reducing it by about 5dB via EQ made a noticeable but not dramatic difference. Directivity error shows up around 3.3kHz, and the upper-midrange around 4-6kHz stood out as edgy and sharp, almost sibilant at times, in casual listening: the predicted in-room response shows a lack of energy between 1-2kHz and a bit too much above that, which one reviewer thought would sound bright. Distortion at 96dB SPL/1m shows two harmonic peaks the reviewer says “should not be there,” one from woofer breakup around 400Hz and another around 7-8kHz from the tweeter, and multitone distortion approaches 10% in the 500-800Hz range at that output level. Real compression shows up even at moderate volume and worsens at 96dB and above, with the woofer clearly giving up around 60-70Hz: a subwoofer is recommended for anyone wanting to listen loud, since running it full-range at high output costs real dynamic range in the midbass and bass. Don’t place it close to a wall: boundary reinforcement adds a midbass bump that undoes the otherwise smooth, linear response. Getting the best out of it takes EQ (taming the 700Hz peak, filling in the 1-2kHz dip, and trimming the highs).

Dynaudio Contour 20i: $5750 per pair Safe and Sound HQ eBay
Pros: Two-way design with a 1.125” Esotar2i silk dome tweeter and a 7” magnesium silicate polymer woofer in a vented enclosure. A shallow bass rolloff profile lets it sit closer to a wall (about 1-2 feet worked best in testing) without becoming boomy, and makes subwoofer integration comparatively easy. Very wide horizontal radiation (about ±70° through the midrange) gives an enveloping, spacious sound in a suitably sized room. On-axis response holds within about ±3dB overall and ±1.5dB through the midrange. Attractive build quality with a distinctive metal front baffle and gloss finish options. Long-term compression stays good up to 96dB, and short-term compression is within about 0.5dB at that same level. Measured bass extension of 56Hz (-3dB).
Cons: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment. A roughly 2dB lift in the lower treble combined with wide dispersion means more energy reflecting off sidewalls than some listeners will prefer. Relatively low sensitivity (about 82.5dB measured). Unusually sensitive to amplifier output impedance: high-output-impedance amps like tube or SET designs introduce up to a 2dB dip in the midrange, making the sound more mellow rather than “warmer,” the opposite of what many tube-amp buyers expect. Elevated harmonic and multitone distortion around 700Hz, which the reviewer attributes to typical cone-edge/surround behavior common across many driver brands, though it stands out on the measurement graphs. An upper-midrange dip around 2kHz can reduce attack and clarity on vocals and brass instruments. Vertical listening window is fairly narrow (roughly -20° to +30°): moving outside that range causes a noticeable tonal shift, unlike coaxial designs that tolerate more vertical movement.
