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.
