Short answer: the MoFi SourcePoint 8. It ranks #9 of 47 bookshelf speakers at $2200; 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 8 side: 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design. Set against that: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis.
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. The tradeoff: 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 8 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 8: $2200 Crutchfield
Pros: 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design; rated 47Hz-30kHz. Notably more neutral and true-to-source than its sibling SourcePoint 10, which the reviewer found a bit too bright in the treble by comparison - measured about 4-5dB less high-frequency output. Excellent imaging: passed multiple stereo-panning and depth tests, including smooth continuous left-to-right pans without wobble and correct front-to-back layering of vocals versus percussion. Wide horizontal dispersion of about ±60°, broader than the reviewer expected from a coaxial design, and forgiving enough in placement that about 10° of toe-out variance and moving above or below the tweeter axis both still sound good. Excellent dynamic range and compression linearity - about 26dB of headroom up to 102dB/1m equivalent, with issues only appearing below about 60Hz. 8-ohm nominal impedance made it easy to drive on everything from a budget Denon AVR to a high-end Macintosh amplifier. No significant evidence of woofer-cone modulation distortion affecting the tweeter, even at 96dB/1m.
Cons: Like other coincident designs, produces diffraction dips around 4kHz and 7kHz when pointed directly on-axis; needs about 10-15° of toe-out to smooth those out. The rear-ported cabinet (two ports) means it can’t be placed too close to a wall without the bass becoming overblown - the reviewer settled on about 2 feet of clearance. F3 of 52Hz and F10 of 43Hz mean genuine deep bass tops out in the mid-40s Hz in-room - a subwoofer is still needed for true low-end extension. Harmonic distortion crosses the reviewer’s 3% threshold at 96dB (though it’s second-order and less audibly significant), and multitone distortion becomes noticeably more audible at that same output level. Vertical response doesn’t perfectly mirror horizontal, since the cabinet is a rectangle rather than a perfect square around the driver.

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.
