Short answer: the JBL L52 Classic, because the JBL Stage A120 has a bat-shaped response and a cabinet resonance, though neither ranks well in its class. The A120 ships with a port bung and the reviewer found it sounded better sealed, but its response boosts bass, scoops the midrange and lifts the treble about 3-4dB above the midrange, partly from confirmed cabinet panel resonance around 800Hz-1.7kHz. The L52 has its own flaw: compression and distortion from about 1-5kHz that were inconsistent across output levels. Both are rated below 3.0/5 among the 90 bookshelf speakers, so if sound quality matters, consider the Philharmonic Ceramic Mini instead, ranked #2 at $900.
Buy the JBL L52 Classic. It is rated higher for sound quality and still sold new, while the JBL Stage A120 is discontinued.

JBL L52 Classic: $999.00 per pair Amazon eBay
Pros: Genuine walnut wood veneer cabinet with a retro Quadrex foam grille (black, orange, or dark blue) reviving JBL’s classic L-series look. 5.25” pure pulp cone woofer and 0.75” titanium dome tweeter on a waveguide, front-firing bass reflex port, in a compact stand-mount cabinet. A pronounced upper-bass bump around 100 Hz gives kick drums a punchy, textured character. Measured bass extension of 62Hz (-3dB), with a measured sensitivity of 85dB.
Cons: Measured compression and distortion behavior from about 1-5 kHz was inconsistent (“wonky”) across output levels, and didn’t clean up even at lower volume; adding a subwoofer high-pass didn’t fix the high-frequency distortion either. Response rolls off quickly above the upper-bass bump, so there’s punch and impact but not real low-end rumble or fundamental weight below about 60 Hz without a subwoofer. Soundstage width was inconsistent track to track, with imaging not staying locked to where instruments should be. Vocals could sound hot and slightly grainy in the 2.5-5 kHz region; pointing the speakers off-axis reduced that sharpness but also killed high-frequency air.

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.
