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 #59 of 160 bookshelf speakers by sound quality (rated 3.6/5), against #143 (rated 2.1/5) for the JBL Stage A130. If you want one new, the JBL Stage 250B replaces the JBL Stage A130 and is rated 3.2/5 at $439.95.
The JBL Stage A130 is the more accurate, deeper-bass choice. More constant, better-behaved directivity than the smaller A120 once past the tweeter crossover point, giving a more consistent radiation pattern that likely explains some of its positive reception among other reviewers. Its measured preference score, a predictor of how neutral it sounds, is 4.04 against 3.53 for the Boston Acoustics A25. Its bass reaches about 66Hz before falling 3dB, against 90Hz for the Boston Acoustics A25. Watch for: Still shows the same underlying “Batman”-shaped response pattern as the A120: a bass bump, a midrange dip, a cabinet-resonance peak around 800Hz-1.7kHz (confirmed via accelerometer testing on the cabinet panels), and roughly a 5dB treble bump around 10kHz.
The Boston Acoustics A25 is the better-sounding option. 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. The catch: 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.
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, buy the JBL Stage 250B, which replaces the JBL Stage A130.

The Two Speakers In Full
JBL Stage A130: $399 per pair Discontinued eBay
Newer model: the JBL Stage 250B, ranked higher, rated 3.2/5.
Older model: the JBL Arena 120 (ranked higher, rated 3.8/5).
Same family: the JBL Stage A120 (smaller bookshelf, ranked higher, rated 2.5/5), the JBL Stage A180 (floorstanding, rated 3.8/5), the JBL Stage A125C (smaller center, rated 3.4/5) and the JBL Stage A135C (larger center, rated 2.9/5).
Pros: More constant, better-behaved directivity than the smaller A120 once past the tweeter crossover point, giving a more consistent radiation pattern that likely explains some of its positive reception among other reviewers. Distortion at 96dB measures slightly better than a direct competitor (Emotiva Airmotiv B1+) in the low end, though slightly worse at high frequencies. The tweeter itself sounded decent to the reviewer, who considers it a reasonable value at its price point despite other reservations. Wide, well-filled horizontal radiation through the midrange. Measured bass extension of 66Hz (-3dB), with a measured sensitivity of 85.2dB.
Cons: Still shows the same underlying “Batman”-shaped response pattern as the A120: a bass bump, a midrange dip, a cabinet-resonance peak around 800Hz-1.7kHz (confirmed via accelerometer testing on the cabinet panels), and roughly a 5dB treble bump around 10kHz. Does not include a port bung, so sealed-cabinet listening requires DIY stuffing rather than a proper factory solution. The reviewer’s own measurements notably diverge from another well-known publication’s results on this same model, possibly reflecting a running production change, though this couldn’t be confirmed. Overall sound quality struck the reviewer as not a good-sounding speaker despite the more favorable measurements relative to the A120. Output-limited at extreme volumes (102dB), similar to its smaller sibling. Loses to the similarly-priced Emotiva Airmotiv B1+ in overall linearity and neutrality, according to the reviewer’s direct comparison. Discontinued.

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.
