Short answer: both are discontinued, and they are rated the same for sound quality (#79 and #80 of 134 bookshelf speakers). Either one is only an option used, so choose on condition and price. If you want one new, the Ascend Acoustics CMT-340 SE2 ranks #23 at $798.

Buy the JBL Studio 630 or the Behringer B2030P, whichever you find used in better condition; both are discontinued. 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.

Behringer B2030P: $220 per pair Discontinued eBay
Pros: CEA2034 spinorama shows strong horizontal directivity control, keeping the response nearly constant off-axis through most of the audible spectrum, with a wide beamwidth that eases seating position and toe-in requirements. Distortion measurements hold up well against the pricier Revel M106 at both 86dB and 106dB SPL. With EQ to tame a resonance around 800Hz and a bit of a bass fill, the reviewer called it a “winner” that could play loud without bottoming out. Measured bass extension of 98.1Hz (-3dB), with a measured sensitivity of 84.5dB.
Cons: A resonance around 800Hz shows up clearly in the on-axis response and the waterfall/CSD plot, and the flat, near-horizontal predicted in-room response makes it sound bright without an equalization target curve. Vertical directivity is only typical, not exceptional. Long discontinued: the reviewer noted you’ll have to hunt for a used pair.
