Short answer: the JBL Stage 250B. It ranks #52 of 88 bookshelf speakers by sound quality, rated 3.2/5, at $439.95. The JBL Stage A120 ranks #67, rated 2.5/5, at $299, $140.95 cheaper, which does not close the gap in sound quality.
What the JBL Stage 250B does well: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The tradeoff: Its objective score is good rather than class-leading, and the rear port needs some wall clearance.
What the JBL Stage A120 does well: Comes with a port bung, letting you experiment between ported and sealed configurations - the reviewer found the sound improved somewhat with the port sealed. The catch: 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.
One note: the JBL Stage A120 is discontinued and no longer widely available new.
Buy the JBL Stage 250B. It is rated higher for sound quality, and the $140.95 saving on the JBL Stage A120 is not enough to make up the difference.

Older model: the JBL Stage A130 (ranked lower, rated 2.1/5).
Pros: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The current Stage 2 model offers solid build details, magnetic grilles and useful 56Hz measured extension at an accessible price. Measured bass extension of 64.5Hz (-3dB).
Cons: Its objective score is good rather than class-leading, and the rear port needs some wall clearance. At 86dB sensitivity and six-ohm nominal impedance it is not especially easy to drive, while the compact woofer limits deep-bass output.

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.
