Short answer: the Polk Audio XT15. It ranks #28 of 71 bookshelf speakers by sound quality at $179; the JBL Stage A130 ranks #59 and costs $399, so there is not much of a tradeoff to weigh.
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. 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. 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), 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.
What the Polk Audio XT15 offers: Very low $179/pair entry price for a Hi-Res Audio Certified 2-way design that’s Dolby Atmos and DTS:X compatible, and works with either 4- or 8-ohm amplifier outputs so it drops into almost any AVR without matching concerns. Directivity spread is reasonably even for the price (directivity_spdi_stddev 3.60). Watch for: Bass rolls off earlier than most of this batch at 77.6Hz (-3dB) / 54.2Hz (-10dB). On-axis deviation is the roughest measured figure here (aad_on_axis 0.449), and listening-window smoothness (0.303) trails the pricier options in this group. Modest 86dB sensitivity wants a reasonably powered amp channel. The 5.25” bi-laminate paper woofer is Polk’s entry-tier driver, not the polypropylene/Turbine cones used in its pricier Signature Elite/Reserve lines.
Buy the Polk Audio XT15. It ranks higher for sound quality than the JBL Stage A130 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the JBL Stage A130. It ranks near the bottom of the 71 bookshelf speakers, so look higher up the list instead.
