These sit in different size classes, so this is not a straight ranking comparison. The JBL Studio 698 ranks #36 of 89 floorstanding speakers by sound quality at $1,499.90; the JBL Studio 630 ranks #83 of 141 bookshelf speakers by sound quality at $699.
The JBL Studio 698 is the more accurate option. High-Definition Imaging (HDI) horn waveguide paired with a 1” compression driver provides excellent high-frequency directivity control and seamless acoustic handoff to the 6” PolyPlas midrange. Its measured preference score, a predictor of how neutral it sounds, is 4.20 against 3.67 for the JBL Studio 630. The catch: Measured response exhibits a prominent mid-bass emphasis bump around 80Hz that can sound overly thick or chesty in smaller rooms without DSP EQ.
What the JBL Studio 630 does well: 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. Watch for: Noticeable mid-range dip/scoop relative to the higher frequencies: not dramatic, but audibly “missing” something by the second or third track.
One note: the JBL Studio 630 is discontinued and no longer widely available new.
Buy the JBL Studio 698 ($1,499.90) for a floorstanding speaker; the JBL Studio 630 ($699) suits a bookshelf speaker instead.

JBL Studio 698: $1,499.90 per pair Crutchfield eBay
Older model: the JBL Studio 590 (ranked lower, rated 2.8/5).
Pros: High-Definition Imaging (HDI) horn waveguide paired with a 1” compression driver provides excellent high-frequency directivity control and seamless acoustic handoff to the 6” PolyPlas midrange. Dual 8” PolyPlas woofers deliver robust low-end authority with solid bass extension down to an F3 of 53Hz and F10 of 34Hz. High voltage sensitivity (90dB SPL at 2.83V/1m) and clean power handling provide effortless dynamic headroom and low distortion for home theater and music listening. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 90dB.
Cons: Measured response exhibits a prominent mid-bass emphasis bump around 80Hz that can sound overly thick or chesty in smaller rooms without DSP EQ. Treble response lacks top-octave ‘air’ above 12kHz compared to high-end dome or ribbon tweeters. Physically large, heavy cabinet (35.8 kg per speaker) requires careful room placement and a wide acoustic footprint.

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.
