Short answer: both are discontinued, so this only matters if you are buying used. Used, the Boston Acoustics A25 is the better pick: it ranks #34 of 90 bookshelf speakers by sound quality (rated 3.6/5), against #44 (rated 3.3/5) for the JBL Studio 530. If you want one new, the Ascend Acoustics HTM-200SE2 ranks #7 at $368.
Buy the Boston Acoustics A25 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 HTM-200SE2 instead.

The Two Speakers In Full
Boston Acoustics A25: $299.98 per pair Discontinued eBay
Pros: CEA2034 spinorama is decent once you ignore a peak around 900Hz and a dip around 3kHz: directivity is good enough that the response can be EQed and won’t be too room-dependent. Cabinet fit and finish is well above its price class, and dynamics were strong with no distortion audible even at high volume on well-recorded material. Discontinued, but the reviewer suggests hunting for clearance pricing on remaining stock. Measured bass extension of 90Hz (-3dB), with a measured sensitivity of 85dB.
Cons: A crazy port resonance and a tweeter with a steeper rolloff than the woofer both show up in the near-field driver measurements, creating the 900Hz peak and the crossover-region dip. The rear port itself measured audibly distorted up close, though it wasn’t noticeable from normal listening distance in the reviewer’s room. Discontinued.

JBL Studio 530: $399 per pair Discontinued eBay
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.
