Short answer: the Polk Audio XT15. It ranks #52 of 160 bookshelf speakers by sound quality (rated 3.7/5) at $149 and is still sold new; the JBL Stage A130 ranks #143 (rated 2.1/5) and is discontinued, so it is only an option used. The JBL Stage A130’s replacement, the JBL Stage 250B, is rated 3.2/5.
The JBL Stage A130 is the deeper-bass pick. 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. Its bass reaches about 66Hz before falling 3dB, against 77.6Hz for the Polk Audio XT15. 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.
The Polk Audio XT15 is the more accurate pick. Very low $149/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. Its measured preference score, a predictor of how neutral it sounds, is 4.56 against 4.04 for the JBL Stage A130. The tradeoff: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB).
Buy the Polk Audio XT15. It is rated higher for sound quality, and the JBL Stage A130 is discontinued, so it is only available used.

The Two Speakers In Full
JBL Stage A130: $399 per pair Discontinued eBay
Newer model: the JBL Stage 250B, ranked higher, rated 3.2/5.
Older model: the JBL Arena 120 (ranked higher, rated 3.8/5).
Same family: the JBL Stage A120 (smaller bookshelf, ranked higher, rated 2.5/5), the JBL Stage A180 (floorstanding, rated 3.8/5), the JBL Stage A125C (smaller center, rated 3.4/5) and the JBL Stage A135C (larger center, rated 2.9/5).
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.

Polk Audio XT15: $149.00 per pair Amazon B&H Photo Video Crutchfield eBay
Same family: the Polk Monitor XT20 (larger bookshelf, rated 3.4/5), the Polk Audio XT60 (smaller floorstanding, rated 3.5/5), the Polk Audio XT70 (larger floorstanding, rated 3.6/5), the Polk Audio XT30 (smaller center, rated 3.6/5), the Polk Audio XT35 (larger center, rated 4.1/5), the Polk Audio Monitor XT10 (smaller subwoofer, estimated 3.1/5) and the Polk Audio Monitor XT12 (larger subwoofer, estimated 3.3/5).
Pros: Very low $149/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. Off axis sound tracks the on axis response reasonably consistently for the price. Measured bass extension of 77.6Hz (-3dB).
Cons: Bass rolls off early, at 77.6Hz (-3dB) and 54.2Hz (-10dB). On-axis response is relatively uneven, with an average deviation of about 0.45dB, and its listening window is less smooth than pricier speakers. 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.
