Short answer: the KEF Q100 for better sound quality, the JBL Stage A130 for the lower price. The KEF Q100 ranks #38 of 56 bookshelf speakers at $550. The JBL Stage A130 ranks #44 at $399, $151 cheaper.
The case for the KEF Q100: 5.25” Uni-Q coaxial driver keeps the tweeter and woofer point-source aligned for consistent imaging. The tradeoff: CEA2034 spinorama shows broad, audible deviations from flat rather than narrow peaks: a lift from 700Hz-1.5kHz and again from 5kHz up, plus a cancellation notch around 1.4kHz from port/cabinet interaction.
What the JBL Stage A130 offers: 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. Watch for: 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).
Buy the KEF Q100 if sound quality matters more than the price. Buy the JBL Stage A130 if the price matters more than sound quality.
If sound quality matters at all to you, skip the JBL Stage A130. It ranks near the bottom of the 56 bookshelf speakers, so look higher up the list instead.

KEF Q100: $550 Discontinued
Pros: 5.25” Uni-Q coaxial driver keeps the tweeter and woofer point-source aligned for consistent imaging. 86dB sensitivity is reasonably easy to drive.
Cons: CEA2034 spinorama shows broad, audible deviations from flat rather than narrow peaks: a lift from 700Hz-1.5kHz and again from 5kHz up, plus a cancellation notch around 1.4kHz from port/cabinet interaction. Bass sensitivity drops to about 80dB and impedance falls below 4 ohms in the bass, demanding a capable amplifier. The reviewer heard boomy, buzzing bass that improved somewhat with the port plugged, and could not recommend it, calling the famous reputation more about looks than sound. Discontinued.

JBL Stage A130: $399 Discontinued
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.
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.
