Short answer: the Micca RB42 on price, the JBL Stage A120 on ranking, though neither ranks well in its class. The RB42 costs $159.99 against $299 and its curved cabinet fit and finish look closer to a far pricier speaker, but its CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up. The A120 places #69 of 90 against #75 of 90, with treble about 3-4dB above the midrange. 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 Micca RB42 if you want one new; the JBL Stage A120 is discontinued, so only look for it used.

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.

Micca RB42: $159.99 per pair Amazon eBay
Pros: Curved cabinet fit and finish look closer to a speaker costing three times as much. Rated for a wide 15-100W amplifier range with 4-8 ohm compatibility, giving flexibility with modest amplification. Measured bass extension of 85Hz (-3dB), with a measured sensitivity of 80dB.
Cons: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up, with excess high-frequency energy the reviewer found fatiguing over time despite an initial impression of “detail.” Off-axis response diverges heavily from on-axis, meaning tonality shifts with room and listening position in ways EQ can’t correct. Distorts and the woofer visibly flaps under moderate volume; low 83dB sensitivity makes it a harder amplifier load than its size suggests.
