Short answer: the Paradigm Monitor SE Atom. The JBL Stage A120’s pronounced “Batman” response, boosted bass, scooped midrange, and treble about 3-4dB above the mids, traces partly to confirmed cabinet panel resonance around 800Hz-1.7kHz, and sealing the supplied port bung only somewhat helped. The Atom’s directivity is more consistent, though its own response dips through 2-4kHz and resonates near 15kHz.

The Two Speakers In Full
Paradigm Monitor SE Atom: $399.98 per pair Paradigm eBay
Pros: Good, consistent directivity across the on-axis, listening-window, and off-axis curves makes the Atom easier to equalize and less room-dependent than many budget speakers. Bass tuning is well judged, letting the woofer play loud on demanding tracks without bottoming out even without a subwoofer. Paradigm’s NRC research pedigree shows in the horizontal and vertical dispersion measurements. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 85dB.
Cons: On-axis response is uneven out of the box, with a 2-4kHz dip followed by a peak and a resonance around 15kHz that the reviewer said gives it a bright, “showroom” voicing without EQ correction. There’s no meaningful bass extension for full-range use, so a subwoofer is effectively required for anything beyond desktop or near-field listening.

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.
