Short answer: the JBL Studio 530, not the scooped Stage A120. The A120 includes a port bung for sealed operation, which the reviewer preferred, but its “Batman” response boosts bass, scoops the midrange and lifts treble about 3-4dB above the midrange, driven partly by cabinet resonance around 800Hz-1.7kHz. The Studio 530 is fairly flat on-axis, its main faults a 1.4kHz tweeter resonance and a 2kHz bump.
Buy the JBL Studio 530 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.

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.

JBL Stage A120: $299 per pair Discontinued eBay
Newer model: the JBL Stage 2 240B. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: Comes with a port bung, letting you experiment between ported and sealed configurations: the reviewer found the sound improved somewhat with the port sealed. Distortion at 96dB is broadly comparable to competitors in this price range outside of some elevated low-end THD. Wide horizontal radiation pattern for a compact bookshelf speaker in the low-to-midrange. Measured bass extension of 71Hz (-3dB), with a measured sensitivity of 83dB.
Cons: A pronounced “Batman”-shaped frequency response: boosted bass, a scooped midrange, and elevated treble (about 3-4dB above the midrange), driven partly by confirmed cabinet panel resonance around 800Hz-1.7kHz. Directivity shows significant back-to-back peaks and dips, making the speaker harder to correct with EQ since the off-axis sound doesn’t track the direct sound cleanly. Elevated treble that some might call “detailed” reads as an unwelcome boost to the reviewer rather than genuine resolution. Compression testing shows the low end degrading substantially at high output (102dB). Overall considered one of the weaker speakers the reviewer has tested in this class, with a competing model (Emotiva Airmotiv B1+) recommended instead at a similar price. Discontinued.
