Short answer: the JBL Studio 630, which avoids the Infinity’s distortion spikes. The IL10 is impressively flat for a budget bookshelf, but it has resonances at 600 and 5kHz that show up as distinct distortion spikes at 96dB SPL/1m in the same regions. The Studio 630 delivers excellent directivity linearity and stable imaging, with a noticeable mid-range dip relative to the higher frequencies as its tradeoff.

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.

Infinity IL10: $160 per pair used Discontinued eBay
Pros: Impressively flat for a budget bookshelf. Predicted in-room response is good aside from a bit of excess energy here and there. Distortion at 96dB SPL/1m stays low and controlled outside two narrow resonance-driven peaks. Measured bass extension of 59Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Resonances at 600 and 5kHz, which show up as distinct distortion spikes at 96dB SPL/1m in the same frequency regions. Discontinued.
