Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Dynaudio X14 is the better pick: it ranks #62 of 90 bookshelf speakers by sound quality (rated 2.9/5), against #69 (rated 2.5/5) for the JBL Stage A120. 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 Dynaudio X14 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 Philharmonic Ceramic Mini instead.

Dynaudio X14: $1,500 per pair Discontinued eBay
Pros: 1” silk-dome tweeter and 5.7” magnesium-silicate-polymer woofer in a compact two-way stand-mount, rated at 85dB sensitivity. Measured bass extension of 67.4Hz (-3dB), with a measured sensitivity of 82dB.
Cons: CEA2034 spinorama shows an uneven on-axis response from the lack of a waveguide to control tweeter beam width, plus a port resonance that boosts the lower midrange and imperfect crossover matching between the drivers. Too much energy in the lower and upper treble reads as bright, and directivity narrows at higher frequencies rather than staying controlled. The reviewer’s verdict: out of the box, the objective performance isn’t that great, though EQ can make it a satisfying speaker. Discontinued.

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.
