Short answer: the JBL Studio 630. It ranks #61 of 105 bookshelf speakers by sound quality at $699; the Focal Aria 906 ranks #72 and costs $2199, so there is not much of a tradeoff to weigh.
On the JBL Studio 630 side: Excellent directivity linearity: harmonics of the same instrument stay collocated in the soundstage instead of drifting between positions, giving precise, stable imaging that holds up well into higher frequencies where many speakers start to beam and narrow. The catch: Noticeable mid-range dip/scoop relative to the higher frequencies - not dramatic, but audibly “missing” something by the second or third track.
What the Focal Aria 906 gets right: CEA2034 spinorama shows very flat bass response, with the reviewer rating overall performance “good.” Predicted in-room response is almost perfect prior to 1kHz. Watch for: 3dB dip around 2.8khz. Some resonance around 800hz, small directivity error around 7khz.
Buy the JBL Studio 630. It ranks higher for sound quality than the Focal Aria 906 and costs less, so there is no real case for the other one.

JBL Studio 630: $699 Amazon
Pros: Excellent directivity linearity: harmonics of the same instrument stay collocated in the soundstage instead of drifting between positions, giving precise, stable imaging that holds up well into higher frequencies where many speakers start to beam and narrow. Good compression behavior - mid-bass stays taut and controlled from low to high volume without the sound falling apart or distorting as you turn it up. A pleasant, controlled mid-bass bump in the 60-100 Hz range adds punch to kick drums without bleeding into an uncontrolled boom on bass guitar. Horizontal radiation holds steady off-axis (about ±60°), so toe-in isn’t fussy. Compared directly to its predecessor, the JBL Studio 530, the reviewer would pick the 630 - smoother trend line through the upper mids and treble, and likely more dynamic headroom - as long as you’re willing to EQ.
Cons: Noticeable mid-range dip/scoop relative to the higher frequencies - not dramatic, but audibly “missing” something by the second or third track. Some tracks read as forward or aggressive around 2 kHz, like the upper frequencies are jumping out at you rather than sitting in stage depth. Needs EQ to bring the mid-range back up to be fully recommendable; without EQ available, the reviewer says he’d look at a different speaker entirely. Measured sensitivity (about 83.2dB) runs noticeably below the 85dB manufacturer spec, likely a byproduct of the mid-range dip skewing the average downward.

Focal Aria 906: $2,199.00 used, Discontinued Amazon
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.
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.
