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 #98 (rated 3.3/5) for the Revel Performa M22. If you want one new, the Ascend Acoustics CMT-340 SE2 ranks #23 at $798.
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 Ascend Acoustics CMT-340 SE2 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.

Revel Performa M22: $600 per pair used (about) Discontinued eBay
Pros: Very flat frequency response from 200Hz to 10kHz. Distortion is well controlled through most of the range, with only a modest crossover-region bump around 2-4kHz. Measured bass extension of 46.9Hz (-3dB).
Cons: 3dB bass boost around 100Hz. On-axis response also droops below 150Hz and peaks above 4kHz, which the reviewer thought may sound a bit bright/light. Distortion rises substantially below 100Hz when driven hard. Discontinued.
