Short answer: the JBL Control 1 Pro, if you are buying new. The JBL Studio 530 ranks higher than it (#80 vs #145 of 160 bookshelf speakers, 3.3/5 vs 2.0/5) but is discontinued, so only consider it used; the JBL Control 1 Pro is still sold new at $240.
The JBL Studio 530 is the more accurate choice. CEA2034 spinorama shows a fairly flat on-axis response. Its measured preference score, a predictor of how neutral it sounds, is 5.21 against 2.87 for the JBL Control 1 Pro. The tradeoff: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz.
The case for the JBL Control 1 Pro: 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 tradeoff: 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 JBL Control 1 Pro, since the JBL Studio 530 is discontinued and only worth hunting down used.

JBL Studio 530: $399 per pair Discontinued eBay
Same family: the JBL Studio 590 (floorstanding, rated 2.8/5) and the JBL Studio 520C (center, rated 3.4/5).
Pros: CEA2034 spinorama shows a fairly flat on-axis response. Predicted in-room response is very smooth aside from the high-frequency roll-off. Measured bass extension of 73.2Hz (-3dB), with a measured sensitivity of 85dB.
Cons: A peak around 1.4kHz is attributed to a tweeter resonance, and shows up as a distinct spike in harmonic distortion at that frequency along with a second resonance-driven bump around 2kHz. Response rolls off in the high frequencies and the tuning is a bit bass-shy overall. Cumulative spectral decay (waterfall) shows the same 1kHz-region resonances lingering in time. Discontinued.

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.
