Short answer: the MoFi SourcePoint 10 for the higher ranking, the HiVi Swans 3.1A Sehlin Sound Solutions mod for the lower price. The MoFi SourcePoint 10 ranks #8 of 47 bookshelf speakers at $3500. The HiVi Swans 3.1A Sehlin Sound Solutions mod ranks #13 at $346.74, $3153.26 cheaper.
The case for the HiVi Swans 3.1A Sehlin Sound Solutions mod: CEA2034 spinorama shows a mostly smooth on-axis response for a DIY three-way kit. Set against that: Some directivity error appears around 2.1kHz on-axis.
What the MoFi SourcePoint 10 gets right: Andrew Jones-designed concentric/coincident driver delivers best-in-class sound power and early-reflections directivity in the reviewer’s. The catch: Like virtually all coincident designs, sounds notably bright pointed directly on-axis due to a deliberate treble lift (meant to compensate.
Buy the HiVi Swans 3.1A Sehlin Sound Solutions mod if the price matters more than the ranking. Buy the MoFi SourcePoint 10 if the ranking matters more than the price.

HiVi Swans 3.1A Sehlin Sound Solutions mod: $346.74 for the kit (assembly required) Amazon
Pros: CEA2034 spinorama shows a mostly smooth on-axis response for a DIY three-way kit. Horizontal beamwidth of about ±70 degrees is wide and consistent. Distortion stays under control down to 40Hz at 96dB SPL/1m, a strong result for a 6.5” woofer in this class.
Cons: Some directivity error appears around 2.1kHz on-axis. Predicted in-room response needs about 1-2dB of correction to fit an ideal target curve. Vertical directivity is just okay, so listening height matters more than with a coincident design. Minimum impedance dips to 3.8 ohms with several peaks, a moderately demanding load. Requires DIY assembly (kit only), with additional Sehlin-mod parts and labor beyond the base kit price.

MoFi SourcePoint 10: $3500 Crutchfield
Pros: 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.
Cons: 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.
