Short answer: the ELAC Debut 2.0 B6.2. It ranks #62 of 100 bookshelf speakers by sound quality at $329; the Sonus Faber Lumina II ranks #66 and costs $1600, so there is not much of a tradeoff to weigh.
On the ELAC Debut 2.0 B6.2 side: 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.
What the Sonus Faber Lumina II offers: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet - genuinely nice-looking speaker with real brand cachet. Watch for: Not a neutral speaker - has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out.
Buy the ELAC Debut 2.0 B6.2. It ranks higher for sound quality than the Sonus Faber Lumina II and costs less, so there is no real case for the other one.

ELAC Debut 2.0 B6.2: $329.00 Amazon Crutchfield
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 Lumina II: $1600 Crutchfield
Pros: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet - genuinely nice-looking speaker with real brand cachet. Bass extension is competitive for the size, reaching about 50 Hz in-room with mild compression and good distortion figures, so higher output levels and greater listening distances aren’t a problem down to that point. About 20 dB of dynamic range at typical listening levels (73 dB at 4m), which comfortably covers most music without the tonal balance shifting as instruments and vocals peak. Off-axis behavior is consistent - toeing the speakers 20-30 degrees out doesn’t meaningfully change the in-room high-frequency character, so placement flexibility is good once you’ve dialed in the tonal balance.
Cons: Not a neutral speaker - has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out. A slightly nasal quality traced to a resonance around 1 kHz that EQ can address. The reviewer needed to trim treble by about 4 dB on his preamp to get the tonal balance he wanted, meaning most listeners will want equalization available to fully enjoy this speaker. At roughly the same $1,000ish price point, alternatives like the Ascend Acoustics Sierra 1 V2 measure more linear (with a tradeoff in distortion and crossover-region directivity), and the Dynaudio Emit 20 offers deeper bass extension and lower compression at the cost of a more deliberately colored tonal signature.
