Short answer: the SVS Prime Bookshelf. It ranks #86 of 125 bookshelf speakers by sound quality at $699; the Sonus Faber Sonetto II G2 ranks #99 and costs $3500, so there is not much of a tradeoff to weigh.
What the SVS Prime Bookshelf offers: Reasonable sensitivity for the price at about 87dB, and the 6.5” woofer sits in its own dedicated sealed sub-compartment inside the cabinet for cleaner midrange/bass separation. Overall response stays within about ±3dB from 80Hz-16kHz, which the reviewer calls reasonable for the price point. Wide, consistent horizontal radiation. Toeing the speakers 30 degrees off-axis smooths the in-room response noticeably if the on-axis tonal balance isn’t to your taste. Watch for: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range. Measured minimum impedance dips below 4 ohms (EPDR even lower), so an 8-ohm-only amplifier or AVR may struggle - a 4-ohm-stable amp or separate amplification is recommended. Bass extension is modest (F3 72Hz, F10 49Hz measured) - SVS clearly designed this to be paired with one of their subwoofers rather than to stand fully alone. Compared directly against its pricier sibling, the SVS Ultra Bookshelf, in the same review, the reviewer found the Ultra noticeably more tonally neutral.
What the Sonus Faber Sonetto II G2 offers: 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. Watch for: 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.
Buy the SVS Prime Bookshelf. It ranks higher for sound quality than the Sonus Faber Sonetto II G2 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Sonus Faber Sonetto II G2. It ranks near the bottom of the 125 bookshelf speakers, so look higher up the list instead.
