Short answer: the ELAC Debut 2.0 B5.2. It ranks #86 of 160 bookshelf speakers by sound quality, rated 3.2/5, at $269. The JBL Control 1 Pro ranks #145, rated 2.0/5, at $240, $29 cheaper, a saving that is not big enough to make up the sound-quality gap.
The ELAC Debut 2.0 B5.2 is the more accurate, deeper-bass choice. Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Its measured preference score, a predictor of how neutral it sounds, is 5.02 against 2.87 for the JBL Control 1 Pro. Its bass reaches about 60Hz before falling 3dB, against 78Hz for the JBL Control 1 Pro. The tradeoff: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance.
What the JBL Control 1 Pro does well: Magnetically shielded transducers and a rugged molded enclosure make it a durable choice for wall-mount or install use, with SonicGuard overload protection built into the crossover. The catch: Sound power and predicted in-room response measurements are badly uneven compared to the JBL 305P Mark II tested alongside it, with no waveguide to control directivity as the woofer beams before handing off to the tweeter.
Buy the ELAC Debut 2.0 B5.2. It is rated higher for sound quality, and the $29 saving on the JBL Control 1 Pro is not enough to make up the difference.

ELAC Debut 2.0 B5.2: $269.00 per pair Amazon eBay
Newer model: the ELAC Debut 3.0 DB53, ranked higher, estimated 3.9/5.
Same family: the ELAC Debut 2.0 B6.2 (larger bookshelf, rated 3.5/5).
Pros: Good horizontal directivity: the off-axis curves track the on-axis response closely, so the broad tonal error responds predictably to EQ. Erin demonstrated that a single high-shelf filter centered near 1.6kHz, about -2dB with Q near 2, substantially improves linearity. Moderate roughly +/-50-60 degree horizontal coverage balances room interaction and image focus. The front port makes close-to-wall placement practical. Erin measured F3 near 60Hz and F10 near 40Hz, useful extension for a compact 5.25-inch two-way. Harmonic distortion is mostly below 1% at 86dB/1m, and low-frequency distortion is better than its size might suggest. Compact cabinet and inexpensive pair pricing make it a workable EQ-assisted desktop or small-room system. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Erin measured a broad +3dB step beginning around 1.5kHz; the resulting elevated upper range sounds tonally uneven even though it is not a narrow, sharp resonance. Native response spans roughly -2.6 to +4dB around the mean, so this is not a neutral speaker without correction. Sensitivity is only about 83dB after correcting the shelf, demanding materially more amplifier voltage than ELAC’s 86dB specification implies. Vertical response changes substantially outside roughly +/-10 degrees of tweeter height. Dynamic compression is the larger limitation: at the highest sweep level it loses roughly 1-1.5dB through the midrange, and even the 86dB trace shows unusual nonlinearity that may involve crossover heating. At about 96dB, multitone distortion rises audibly around 600Hz; an 80-120Hz subwoofer crossover helps but does not turn it into a high-output design. Erin recommends the larger B6.2 instead when EQ is unavailable.

JBL Control 1 Pro: $240 per pair Parts Express eBay
Pros: Magnetically shielded transducers and a rugged molded enclosure make it a durable choice for wall-mount or install use, with SonicGuard overload protection built into the crossover. Feels solidly built despite the low price, and the professional crossover network uses steep slopes. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 87dB.
Cons: Sound power and predicted in-room response measurements are badly uneven compared to the JBL 305P Mark II tested alongside it, with no waveguide to control directivity as the woofer beams before handing off to the tweeter. The reviewer performed no distortion or dedicated listening test on this unit and concluded he didn’t “think there is a reason to purchase it” over a proper studio monitor at a similar price.
