Short answer: the KEF Q150. It ranks #26 of 88 bookshelf speakers by sound quality, rated 3.7/5, at $350; the JBL Stage A130 ranks #76, rated 2.1/5, and costs $399, which makes this an easy call rather than a real tradeoff.
What the KEF Q150 does well: Two-way coaxial (Uni-Q) design with a 1” dome tweeter and 5.25” mid-range time-aligned in a single driver assembly, available in ported or sealed configuration. The catch: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one: a real preference factor depending on your room’s furnishings.
What the JBL Stage A130 does well: More constant, better-behaved directivity than the smaller A120 once past the tweeter crossover point, giving a more consistent radiation pattern that likely explains some of its positive reception among other reviewers. The tradeoff: Still shows the same underlying “Batman”-shaped response pattern as the A120: a bass bump, a midrange dip, a cabinet-resonance peak around 800Hz-1.7kHz (confirmed via accelerometer testing on the cabinet panels), and roughly a 5dB treble bump around 10kHz.
One note: the KEF Q150 is discontinued, but it still ranks #26 of 88 bookshelf speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the KEF Q150. It is rated higher for sound quality than the JBL Stage A130 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
KEF Q150: $350 per pair Discontinued Amazon eBay
Newer model: the KEF Q1 Meta, ranked lower, rated 3.6/5.
Pros: Two-way coaxial (Uni-Q) design with a 1” dome tweeter and 5.25” mid-range time-aligned in a single driver assembly, available in ported or sealed configuration. Exceptional soundstage depth, a hallmark of KEF’s coaxial designs that the reviewer says few other speakers match. Bass extension reaches into kick-drum territory, respectable for a compact bookshelf speaker. Resonances present in measurements are consistent across on- and off-axis readings, meaning they can be effectively corrected with EQ. Distortion profile is essentially the same whether run sealed or ported, since a subwoofer crossover point sits above where the differences would matter anyway. At its sale price (around $300, sometimes seen at $400), the reviewer considers it a clear step up from his previous budget favorite in this range, the Emotiva B1+, mainly due to the superior soundstage depth. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 85dB.
Cons: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one: a real preference factor depending on your room’s furnishings. A mild dip in the 1-2kHz region reduces vocal fullness somewhat. Unexplained resonances appear in measurements and persist in both sealed and ported configurations, pointing to enclosure or panel vibration rather than the port. Horizontal radiation is narrower than the reviewer generally prefers from KEF’s lineup, with directivity that widens somewhat around 1.2kHz (near a resonance) and again above about 5kHz. Compression testing at high output (102dB) shows significant nonlinearity, especially at lower frequencies: noticeably worse than a comparable Arendal bookshelf speaker costing over twice as much, which held up better until 80Hz. Not intended for loud listening without a subwoofer: the woofer will over-exert itself without a high-pass filter, and the reviewer recommends crossing over at 80-120Hz. At full retail price (around $600/pair), the value proposition is far less certain than at sale pricing. Discontinued.

JBL Stage A130: $399 per pair Discontinued eBay
Newer model: the JBL Stage 250B, ranked higher, rated 3.2/5.
Pros: More constant, better-behaved directivity than the smaller A120 once past the tweeter crossover point, giving a more consistent radiation pattern that likely explains some of its positive reception among other reviewers. Distortion at 96dB measures slightly better than a direct competitor (Emotiva Airmotiv B1+) in the low end, though slightly worse at high frequencies. The tweeter itself sounded decent to the reviewer, who considers it a reasonable value at its price point despite other reservations. Wide, well-filled horizontal radiation through the midrange. Measured bass extension of 66Hz (-3dB), with a measured sensitivity of 85.2dB.
Cons: Still shows the same underlying “Batman”-shaped response pattern as the A120: a bass bump, a midrange dip, a cabinet-resonance peak around 800Hz-1.7kHz (confirmed via accelerometer testing on the cabinet panels), and roughly a 5dB treble bump around 10kHz. Does not include a port bung, so sealed-cabinet listening requires DIY stuffing rather than a proper factory solution. The reviewer’s own measurements notably diverge from another well-known publication’s results on this same model, possibly reflecting a running production change, though this couldn’t be confirmed. Overall sound quality struck the reviewer as not a good-sounding speaker despite the more favorable measurements relative to the A120. Output-limited at extreme volumes (102dB), similar to its smaller sibling. Loses to the similarly-priced Emotiva Airmotiv B1+ in overall linearity and neutrality, according to the reviewer’s direct comparison. Discontinued.
