Short answer: the Sonetto II G2 for tonal accuracy, the Lumina II Amator for looks and price. The Sonetto runs 2-5dB cooler in the treble and reaches a genuine 50Hz in-room, though it still sounds bright on-axis until toed out about 30 degrees. The Lumina II Amator has solid bass extension at F3 63Hz and a gorgeous cabinet, but runs 3-6dB above the midrange, the brightest of the three Sonus Faber models tested.
Sonetto II G2’s two-way design is notably more neutral than Sonus Faber’s own Lumina 2, running 2-5dB cooler in the treble, with well-behaved horizontal directivity and bass reaching a genuine 50Hz in-room. It still sounds bright pointed directly on-axis; toeing it out about 30 degrees tames the sibilance.
Lumina II Amator has solid bass extension for a bookshelf (F3 63Hz) and wide, consistent horizontal dispersion in a gorgeous cabinet, but its treble runs 3-6dB above the midrange depending on angle, making it the brightest of three Sonus Faber models Erin’s Audio Corner has tested, even brighter than the Sonetto II G2.
Buy the Sonetto II G2 if tonal accuracy is the priority and the price premium is acceptable, toeing it out to tame its own brightness. Buy the Lumina II Amator if the striking cabinet design and lower price matter more, and plan on EQ or careful placement to manage its brighter treble.

Sonus Faber Sonetto II G2: $3500 per pair Crutchfield eBay
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. Measured bass extension of 62Hz (-3dB), with a measured sensitivity of 87dB.
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.

Sonus Faber Lumina II Amator: $2000 per pair Crutchfield eBay
Pros: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. Decent sensitivity and wide, consistent horizontal dispersion (~60-70 degrees): better directivity than expected for a two-way design. Gorgeous, luxury-grade cabinet design. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 86.9dB.
Cons: Very bright treble, running 3-6dB above the midrange depending on measurement angle: independently corroborated by other owners online, not just one reviewer’s opinion. Causes audible sibilance and a forward, grainy character. Notably the brightest of three Sonus Faber models Erin’s Audio Corner has tested, even brighter than the brand’s own Sonetto II G2. A mechanical resonance/ringing artifact shows up around 1kHz in measurements. Needs a subwoofer for anything below about 50Hz.
