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 #123 of 203 bookshelf speakers by sound quality (rated 3.6/5), against #169 (rated 3.0/5) for the Emotiva Airmotiv B2+. If you want one new, the Emotiva Airmotiv XB2 replaces the Emotiva Airmotiv B2+ and is rated 4.2/5 at $549.
Choose the JBL Studio 630 for excellent directivity linearity: Watch for: noticeable mid-range dip/scoop relative to the higher frequencies - not dramatic, but audibly “missing” something by the second or third track. It costs more too, at $699 against $449.
Choose the Emotiva Airmotiv B2+ for erin measured a useful 86dB average sensitivity and strong midbass: Watch for: the replacement B2+ did not deliver the neutral upgrade Erin expected. It’s also the cheaper of the two, at $449 against $699.
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, buy the Emotiva Airmotiv XB2, which replaces the Emotiva Airmotiv B2+.

The Two Speakers In Full
JBL Studio 630: $699 per pair Discontinued eBay
Same family: the JBL Studio 698 (floorstanding, rated 4.3/5).
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.

Emotiva Airmotiv B2+: $449 per pair Discontinued eBay
Newer model: the Emotiva Airmotiv XB2, ranked higher, rated 4.2/5.
Same family: the Emotiva Airmotiv T2+ (floorstanding, rated 4.2/5) and the Emotiva Airmotiv C2+ (center, rated 2.9/5).
Pros: Erin measured a useful 86dB average sensitivity and strong midbass punch around 120Hz. The folded-ribbon tweeter provides very broad upper-treble radiation, and the speaker can create a spacious presentation when positioned carefully. Response and directivity remain reasonably orderly below the roughly 2kHz crossover region. The 6.5-inch woofer offers more output capability than compact 5-inch competitors, while F3/F10 of 66/43Hz leave adequate overlap for a conventional 80Hz subwoofer crossover. Horizontal directivity data makes the broad baffle-step trend amenable to partial EQ below the crossover. Measured bass extension of 66Hz (-3dB), with a measured sensitivity of 86dB.
Cons: The replacement B2+ did not deliver the neutral upgrade Erin expected. A baffle-step loss around 500Hz depresses the lower midrange while the AMT’s much wider radiation above crossover injects excess room energy, yielding a bright, forward balance and false impression of cymbal detail. The directivity discontinuity near 2kHz cannot be completely equalized. Erin measured F3 at 66Hz and F10 at 43Hz, so meaningful kick-drum fundamentals and low bass still need a subwoofer. Vertical listening tolerance is roughly +/-10 degrees, with best results between the top of the woofer and tweeter axes. Broad lateral treble energy may require careful toe-out and sidewall absorption. Despite a large cabinet, it offers limited deep-bass advantage and was not Erin’s hoped-for successor to the more linear Emotiva B1+. Discontinued.
