Short answer: the MoFi SourcePoint 8. It ranks #17 of 131 bookshelf speakers by sound quality, rated 4.5/5, at $2,594. The Focal Aria 906 ranks #94, rated 3.3/5, at $2,199, $395 cheaper, which does not close the gap in sound quality.
What the MoFi SourcePoint 8 does well: 8” twin-drive concentric driver paired with a 1.25” soft dome tweeter, in a diffraction-reducing baffle design; rated 47Hz-30kHz. The catch: 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.
Why pick the Focal Aria 906: CEA2034 spinorama shows very flat bass response, with the reviewer rating overall performance “good.” Watch for: 3dB dip around 2.8kHz.
Worth knowing: the Focal Aria 906 has been discontinued and is hard to find new at this point.
Buy the MoFi SourcePoint 8. It is rated higher for sound quality, and the $395 you would save on the Focal Aria 906 does not close the gap.

MoFi SourcePoint 8: $2594 per pair Crutchfield eBay
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. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 86.3dB.
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.

Focal Aria 906: $2,199.00 per pair used Discontinued Amazon eBay
Newer model: the Focal Aria Evo X N°1. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: CEA2034 spinorama shows very flat bass response, with the reviewer rating overall performance “good.” Predicted in-room response is almost perfect prior to 1kHz. Horizontal dispersion of about ±60 degrees is good and stays even out to about -12dB before getting erratic. Woofer distortion is quite low at 86dB SPL/1m. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: 3dB dip around 2.8kHz. Some resonance around 800Hz, small directivity error around 7kHz. A dip in the upper midrange also shows up in the predicted in-room response. Distortion becomes problematic at 96dB SPL/1m, with a notable peak around 1.3-1.5kHz alongside broader midrange elevation. Discontinued.
