Short answer: the JBL Stage A130 on ranking, the Definitive Technology ProMonitor 1000 on price, though neither ranks well in its class. The A130 places #78 of 90 against the ProMonitor 1000’s #82 of 90. The ProMonitor’s rolloff helps it handle hard use, but its spinorama shows reduced bass energy between 40-120Hz, a directivity mismatch and a resonance around 14kHz. The A130’s directivity is more constant than the A120’s, but it keeps the “Batman” shape. Both are rated below 3.0/5 among the 90 bookshelf speakers; for better sound, the Ascend Acoustics HTM-200SE2 ranks #7 at $368.
Buy the Definitive Technology ProMonitor 1000 new; the JBL Stage A130 is no longer sold new, so it only makes sense as a used find.

JBL Stage A130: $399 per pair Discontinued eBay
Newer model: the JBL Stage 250B, ranked higher, rated 3.2/5.
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.

Definitive Technology ProMonitor 1000: $498 per pair Amazon eBay
Pros: Bass distortion is well controlled per the measurements, and the slow bass rolloff means it can be pushed fairly hard for its size. Ships with a footer that keeps the small cabinet planted despite its light weight. Measured bass extension of 95Hz (-3dB), with a measured sensitivity of 86dB.
Cons: CEA2034 spinorama shows severely reduced bass energy between 40-120Hz, a directivity mismatch between the tweeter and woofer, and a severe resonance/interference issue around 14kHz. Distortion at 96dB SPL was so bad the reviewer limited testing to 86dB. Direct comparison to a $118/pair Pioneer SP-BS22-LR left the reviewer calling the $249/pair ProMonitor 1000 “a bad experiment that should be forgotten” and concluding “there is nothing Pro about it.”
