Short answer: the Sonus Faber Sonetto II G2. It ranks #158 of 188 bookshelf speakers by sound quality (rated 3.1/5) at $3,500 and is still sold new; the Sonus Faber Sonetto II ranks #163 (rated 3.0/5) and is discontinued, so it is only an option used.
Why pick the Sonus Faber Sonetto II G2: 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.
Why pick the Sonus Faber Sonetto II: A two-way stand-mount with a 6.5” paper pulp woofer, a 29mm silk dome tweeter and a downward-firing port in Sonus Faber’s curved wood cabinet. The tradeoff: The response is uneven (0.53 on-axis deviation), for a preference score of 3.97 that reaches 5.92 with an ideal subwoofer.
Buy the Sonus Faber Sonetto II G2. It is rated higher for sound quality, and the Sonus Faber Sonetto II is discontinued, so it is only available used.

Sonus Faber Sonetto II G2: $3500 per pair Crutchfield eBay
Older model: the Sonus Faber Sonetto II (ranked lower, rated 3/5).
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 Sonetto II: $2,500 per pair Discontinued eBay
Newer model: the Sonus Faber Sonetto II G2, ranked higher, rated 3.1/5.
Pros: A two-way stand-mount with a 6.5” paper pulp woofer, a 29mm silk dome tweeter and a downward-firing port in Sonus Faber’s curved wood cabinet. Measurements show good bass for its size, 58Hz (-3dB) and about 37Hz (-10dB). Measured bass extension of 58Hz (-3dB).
Cons: The response is uneven (0.53 on-axis deviation), for a preference score of 3.97 that reaches 5.92 with an ideal subwoofer. That data is low quality, from a reviewer’s home measurement. The load is 4 ohms. Sonus Faber replaced it with the Sonetto II G2. Discontinued.
