Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Studio 630 is the better pick: it ranks #79 of 134 bookshelf speakers by sound quality (rated 3.6/5), against #97 (rated 3.3/5) for the Focal Aria 906. If you want one new, the AsciLab C6B ranks #6 at $1,145.
Buy the JBL Studio 630 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the AsciLab C6B instead.

The Two Speakers In Full
JBL Studio 630: $699 per pair Discontinued eBay
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. Measured bass extension of 54.2Hz (-3dB), with a measured sensitivity of 83.2dB.
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. Discontinued and no longer sold new.

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.
