Short answer: the JBL Stage A120, narrowly, on price and ranking, though neither ranks well in its class. It places #69 of 90 against the Q Acoustics 3020i’s #72 of 90 and costs $299 against $314.99. The 3020i is UK-designed with attractive styling, but its on-axis response shows a rising upper-frequency trend, a dip in the 2-4kHz crossover region, two resonance-related dips and a 366Hz waterfall resonance. The A120’s response is “Batman”-shaped. Both are rated below 3.0/5 among the 90 bookshelf speakers, and the Ascend Acoustics HTM-200SE2, ranked #7 at $368, is a better place to start if sound quality matters.
Buy the JBL Stage A120 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.

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 3020i: $314.99 per pair Discontinued eBay
Newer model: the Q Acoustics 3020c. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: UK-designed (Finkteam) with attractive styling, including recessed binding posts and custom connectors. Vertical directivity is good enough that the tweeter doesn’t need to be exactly at ear level. With EQ correction, especially high-frequency shelving and a sub-40Hz high-pass filter, Amir found performance “improves substantially.”. Measured bass extension of 82.0Hz (-3dB).
Cons: On-axis response shows a rising upper-frequency trend and a dip in the 2-4kHz crossover region alongside two resonance-related dips; a significant resonance appears at 366Hz in the waterfall plot. Horizontal directivity is narrow and uneven due to a woofer/tweeter beamwidth mismatch. Amir cautions the speaker is “merely a distortion generator” if played too low, and its low impedance demands a quality amplifier. Without EQ, Amir “can’t recommend the Q Acoustics 3020i.”. Discontinued; Q Acoustics now sells the 3030i and 3010c in its place.
