Short answer: the Aalto Speakers Aalto 3 Passive. It ranks #54 of 222 bookshelf speakers by sound quality (rated 4.2/5); the Sonus Faber Lumina II Amator ranks #188 (rated 3.0/5).
The Aalto Speakers Aalto 3 Passive is the better-sounding, deeper-bass option. The passive version of the same cabinet as Aalto’s Active Pro model, sharing its 26mm aluminum tweeter and 6.5” bass-midrange driver but without the built-in amp module, for buyers who already have their own amplification. Its bass reaches about 56.6Hz before falling 3dB, against 63Hz for the Sonus Faber Lumina II Amator. The tradeoff: Requires an external amplifier (50-250W recommended) that the Active Pro doesn’t, and shares the same review gap: no independent editorial coverage found, only manufacturer-supplied specs, with factory-direct-only sales from Finland.
The case for the Sonus Faber Lumina II Amator: Solid bass extension for a bookshelf (F3 63Hz, F10 43Hz), reaching about 50Hz in-room. Watch for: 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.

The Two Speakers In Full
Aalto Speakers Aalto 3 Passive: €3,490 per pair Aalto Speakers eBay
Same family: the Aalto Speakers Aalto 1 EVO (smaller bookshelf, rated 4.3/5), the Aalto Speakers Aalto 3 Active Pro (larger bookshelf, rated 4.7/5) and the Aalto Speakers Aalto 9 (floorstanding, rated 4.7/5).
Pros: The passive version of the same cabinet as Aalto’s Active Pro model, sharing its 26mm aluminum tweeter and 6.5” bass-midrange driver but without the built-in amp module, for buyers who already have their own amplification. Measures a -3dB extension of 56.6Hz with an on-axis deviation of 0.192dB, close to tonally neutral, a well-damped bass-alignment Q of 0.64, and reaches a deeper 34Hz Harman in-room extension estimate.
Cons: Requires an external amplifier (50-250W recommended) that the Active Pro doesn’t, and shares the same review gap: no independent editorial coverage found, only manufacturer-supplied specs, with factory-direct-only sales from Finland.

Sonus Faber Lumina II Amator: $2000 per pair Crutchfield $2000 eBay
Same family: the Sonus Faber Lumina I (smaller bookshelf, estimated 3.3/5), the Sonus Faber Lumina II (smaller bookshelf, ranked higher, rated 3.4/5), the Sonus Faber Lumina III (smallest floorstanding, estimated 3.5/5), the Sonus Faber Lumina V (floorstanding, estimated 3.6/5), the Sonus Faber Lumina V Amator (largest floorstanding, estimated 3.5/5) and the Sonus Faber Lumina Center I (center, estimated 3.5/5).
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 Sonus Faber Sonetto II G2. A mechanical resonance/ringing artifact shows up around 1kHz in measurements. Needs a subwoofer for anything below about 50Hz.
