Short answer: the MoFi SourcePoint 10. It ranks #8 of 47 bookshelf speakers at $3500; the Radiant Acoustics Clarity 6.2 ranks #10 and costs $4500, so there is not much of a tradeoff to weigh.
On the MoFi SourcePoint 10 side: 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.
The case for the Radiant Acoustics Clarity 6.2: Custom AMT (Air Motion Transformer) tweeter paired with a 6.5” Purifi Eikona midrange and dual Purifi passive radiators. Set against that: Needs a fairly specific setup to sound its best: about 15-20° of toe-out (per the manufacturer’s own recommendation) and roughly 2 feet.
Buy the MoFi SourcePoint 10 if the ranking matters more than the price. Buy the Radiant Acoustics Clarity 6.2 if the price matters more than the ranking.

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.

Radiant Acoustics Clarity 6.2: $4500 Radiantacoustics
Pros: Custom AMT (Air Motion Transformer) tweeter paired with a 6.5” Purifi Eikona midrange and dual Purifi passive radiators in a passive-radiator enclosure, crossed over at 2.4kHz. Rigid cabinet construction (21mm MDF with a 15mm aluminum front baffle, extensive internal bracing) helps keep resonance in check. A deliberately rising on-axis response paired with narrowing directivity above about 2kHz yields a genuinely linear, non-fatiguing in-room sound rather than the “fake detail” of speakers with a straight treble boost. Excellent pair matching between units (within about 1dB), contributing to precise, well-focused imaging that clearly separated fine details in test tracks. In-room bass extension reaches a solid 40Hz with real kick-drum authority, not just sub-bass rumble. Class-leading dynamic range and compression performance - among the best the reviewer has measured at this price point.
Cons: Needs a fairly specific setup to sound its best: about 15-20° of toe-out (per the manufacturer’s own recommendation) and roughly 2 feet from the rear wall; pointed straight on-axis, the treble reads as noticeably elevated. Low impedance (2.1-ohm minimum, about 1-ohm minimum EPDR) demands an amplifier genuinely comfortable with 4-ohm-and-below loads. Soundstage width narrows above about 5kHz, even though the AMT tweeter itself is capable of wider dispersion. An unexplained resonance appears in harmonic distortion measurements on both units tested (though not on the reviewer’s reference speaker) - possibly a basket resonance, and not something the reviewer could hear. A minor bump around 500Hz in the estimated in-room response could add a touch of boxiness for some listeners, though the reviewer didn’t personally notice it. F3 of 55Hz and F10 of 32Hz mean a subwoofer is still needed for home-theater rumble or bass-heavy genres like rap.
