Short answer: the Sonus Faber Sonetto II G2, if you are buying new. The Sonus Faber Sonetto II measures as well as the Sonus Faber Sonetto I G2 (#173 vs #107 of 160 bookshelf speakers) but is discontinued; its replacement, the Sonus Faber Sonetto II G2, is rated 3.1/5 at $3,500 and is still sold new.
What the Sonus Faber Sonetto I G2 does well: The smallest standmount in the Sonetto G2 range, with the same 1.1” DAD Arrow Point tweeter as the measured Sonetto II G2 above a 5” natural fiber midwoofer, crossed over at 2.1kHz. The catch: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sonetto II G2, which showed an uneven listening window (a 4.25 Spinorama preference score).
What the Sonus Faber Sonetto II does well: 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, the replacement for the discontinued Sonus Faber Sonetto II; it is rated higher for sound quality than the Sonus Faber Sonetto I G2.
Worth knowing: the Sonus Faber Sonetto I G2 has not been measured yet. Its rating is estimated from related models, with a likely range of 2.6 to 3.4, so treat this verdict as provisional.

Sonus Faber Sonetto I G2: $2,500.00 per pair Estimated Audio Advice eBay
Same family: the Sonus Faber Sonetto II G2 (larger bookshelf, rated 3.1/5), the Sonus Faber Sonetto III G2 (smaller floorstanding, estimated 3.2/5), the Sonus Faber Sonetto V G2 (larger floorstanding, estimated 3.3/5) and the Sonus Faber Sonetto Center G2 (center, estimated 3/5).
Pros: The smallest standmount in the Sonetto G2 range, with the same 1.1” DAD Arrow Point tweeter as the measured Sonetto II G2 above a 5” natural fiber midwoofer, crossed over at 2.1kHz. The front-facing port lets it sit nearer a wall, and the lute-shaped wood cabinet with leather top and concrete base is finished to a high standard.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the measured Sonetto II G2, which showed an uneven listening window (a 4.25 Spinorama preference score). Sensitivity is 86dB into a 4 ohm load and bass is rated only to 52Hz, so pair it with a subwoofer and a solid amplifier.

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.
