ELAC Debut 2.0 B6.2 vs Sonus Faber Sonetto II G2

Last updated: August 19, 2026

Short answer: the ELAC Debut 2.0 B6.2. It ranks #67 of 105 bookshelf speakers by sound quality at $329; the Sonus Faber Sonetto II G2 ranks #79 and costs $3500, so there is not much of a tradeoff to weigh.

What the ELAC Debut 2.0 B6.2 gets right: 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. Set against that: 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.

On the Sonus Faber Sonetto II G2 side: Two-way design with a 1.125” damped Apex Dome silk tweeter and 6.5” cone woofer, using a base of concrete, aluminum, and steel with under-cabinet venting. Watch for: Sounds notably bright pointed directly on-axis; toeing the speaker out about 30° reduces treble energy and sibilance meaningfully.

Buy the ELAC Debut 2.0 B6.2. It ranks higher for sound quality than the Sonus Faber Sonetto II G2 and costs less, so there is no real case for the other one.

If sound quality matters at all to you, skip the Sonus Faber Sonetto II G2. It ranks near the bottom of the 105 bookshelf speakers, so look higher up the list instead.

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.

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).

Sonus Faber Sonetto II G2: $3500 Crutchfield

Sonus Faber Sonetto II G2 ranking card

Pros: Two-way design with a 1.125” damped Apex Dome silk tweeter and 6.5” cone woofer, using a base of concrete, aluminum, and steel with under-cabinet venting. Notably more neutral than Sonus Faber’s own Lumina 2, which runs 2-5dB hotter in the treble. Horizontal directivity narrows at a fairly constant, well-behaved rate rather than narrowing-then-widening-then-narrowing like some rivals (including the Lumina 2), meaning sidewall reflections match the direct sound well enough that the reviewer doesn’t recommend sidewall absorption for this speaker. The tweeter-to-woofer crossover handoff around 3kHz looks clean, suggesting a higher-order crossover than typical for the size/price class. Good dynamic range - the low end loses only about 2dB from 76dB to 96dB, otherwise holding up well. Not a difficult amplifier load (about 4.2 ohms minimum impedance). Bass extension reaches a genuine 50Hz in-room, fuller than the Lumina 2.

Cons: Sounds notably bright pointed directly on-axis; toeing the speaker out about 30° reduces treble energy and sibilance meaningfully. A resonance around 700Hz gives vocals a slightly nasal, hollow quality. A dip in the upper midrange (roughly 1-2kHz) reduces perceived detail and attack, while the elevated treble can read as “analytical” or “detailed” to some listeners despite being a coloration rather than true resolution. Needs more clearance from the rear wall than some rivals - about 1.5-2 feet in an ideal room, more or less depending on your specific room modes - or the 80-120Hz region can become boomy. Vertical listening window is limited to about ±10-15° from the tweeter axis. Some unexplained directivity irregularities appear around 1.2kHz and 1.6kHz, possibly port-related, along with a longer decay in the 800Hz-1600Hz range in burst-decay measurements. Multitone distortion approaches the reviewer’s 3% threshold through the midrange, though likely not obviously audible without direct A/B comparison. A resonance in the cabinet appears around 400Hz in impedance measurements.
