Short answer: the MoFi SourcePoint 10 for better sound quality, the Sonus Faber Sonetto II G2 for the lower price. The MoFi SourcePoint 10 ranks #26 of 130 bookshelf speakers at $3795. The Sonus Faber Sonetto II G2 ranks #103 at $3500, $295 cheaper.
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.
What the MoFi SourcePoint 10 offers: Andrew Jones-designed concentric/coincident driver delivers best-in-class sound power and early-reflections directivity in the reviewer’s testing - a genuine “point source” design. Vertical and horizontal radiation patterns closely match each other (about ±50° horizontal, ±30-40° vertical), a hallmark benefit of a well-executed concentric driver. Distortion stays low - under 1% above 100Hz at 86dB, and under 3% up to 100Hz even at 96dB, better than the reviewer expected from a low-excursion waveguide-loaded woofer. Surprisingly strong dynamic capability with little audible compression at both low and high volume. Widely spaced (about 11 feet apart) with roughly 15° of toe-out produced a huge, expansive soundstage without significant loss of imaging precision. Solidly built cabinet (about 40 lbs, heavily braced) minimizes cabinet resonance. Watch for: Like virtually all coincident designs, sounds notably bright pointed directly on-axis due to a deliberate treble lift (meant to compensate for the 28mm tweeter’s earlier beaming versus a typical 25mm/1” tweeter) combined with a diffraction dip/peak from the waveguide edge; needs about 15° of toe-out to sound neutral, and even then benefits from an extra 1-2dB of treble EQ. Toeing out further (to 30°) flattens the treble further but introduces a dip in the midrange-to-tweeter crossover region - there’s no single toe-out angle that fixes everything at once. F3 of 56Hz and F10 of 38Hz (about 40Hz in-room) mean genuine deep bass is limited; the reviewer would pair it with a sealed 10” or 12” subwoofer for regular daily listening. Bass extension and cabinet placement trade off against midrange cleanliness: placing it close to a wall for more bass risks a wall-bounce suckout in the midrange (roughly 200-500Hz depending on distance). Not perfectly time-aligned between tweeter and woofer (about 0.4ms delta), an inherent limitation of passive coincident drivers versus actively time-corrected designs. Some resonances appear in measurements, likely port-related. Minimum impedance around 6.4 ohms with EPDR near 3 ohms, so the reviewer recommends sticking with a 4-ohm-rated amplifier to be safe.
Buy the Sonus Faber Sonetto II G2 if the price is the priority over sound quality, or the MoFi SourcePoint 10 if sound quality is the priority over the price.
If sound quality matters at all to you, skip the Sonus Faber Sonetto II G2. It ranks near the bottom of the 130 bookshelf speakers, so look higher up the list instead.
