Short answer: the Q Acoustics 5020, if you are buying new, though neither ranks well in its class. The JBL Stage A120 ranks higher than it (#69 vs #76 of 90 bookshelf speakers, 2.5/5 vs 2.2/5) but is discontinued, so only consider it used; the Q Acoustics 5020 is still sold new at $1,199. Both are rated below 3.0/5 among the 90 bookshelf speakers; for better sound, the Philharmonic Ceramic Mini ranks #2 at $900.
Buy the Q Acoustics 5020 new; the JBL Stage A120 is no longer sold new, so it only makes sense as a used find.

The Two Speakers In Full
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.

Q Acoustics 5020: $1,199.00 per pair Amazon eBay
Pros: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. Erin found distortion well controlled at normal levels: below 1% down to about 50Hz at 86dB/1m. Its 87dB measured sensitivity is unremarkable rather than hard to drive, and it maintains acceptable output for typical 80-85dB listening. The rear port can be plugged for placement flexibility. Measured bass extension of 103Hz (-3dB), with a measured sensitivity of 87.1dB.
Cons: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range. The shallow woofer crossover and steeper tweeter slope contribute to the off-axis discontinuity, while the port has a strong 1kHz resonance. Bass is limited: Erin measured F3 103Hz and F10 48Hz; at 96dB distortion reaches about 3% by 100Hz, and he bottomed the woofer when pushed hard. He preferred the less-expensive 3020i’s linearity and did not recommend the 5020 for neutral listening without EQ.
