JBL Stage A120 - ranked #98 of 122 Medium Size Bookshelf Speakers · Editor's rating 2.5/5

#98 JBL Stage A120: $299 per pair Discontinued eBay

Newer model: the JBL Stage 2 240B, ranked higher, estimated 2.7/5.

Larger model: the JBL Stage A130 (ranked lower, rated 2.1/5).

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.

How it compares: Just above it: Parts Express Copperhead Desktop Kit - $179 cheaper, 2Hz lower bass extension (-3dB). Just below it: ELAC Uni-Fi 2.0 UB52 - $500 more, 0.3Hz higher bass extension (-3dB).
