Short answer: the Wharfedale Diamond 12.1. It ranks #21 of 88 bookshelf speakers by sound quality, rated 3.9/5, at $599. The JBL Stage A130 ranks #76, rated 2.1/5, at $399, $200 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Wharfedale Diamond 12.1: A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. The catch: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material: possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat.
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.
Worth knowing: the Wharfedale Diamond 12.1 is discontinued, though it still ranks #21 of 88 bookshelf speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Wharfedale Diamond 12.1. It is rated higher for sound quality, and the $200 saving on the JBL Stage A130 is not enough to make up the difference.

Newer model: the Wharfedale Diamond 12.1i. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. Wide horizontal radiation of about ±60° up to roughly 5kHz before the tweeter starts to beam. Tonally smooth and easy to listen to at moderate volumes, with a pleasant, non-fatiguing character the reviewer said he’d happily recommend to someone who wants noticeably better fit, finish and looks than typical speakers in the $300-400 range. A high-pass crossover around 80Hz meaningfully cleans up midrange multitone distortion, so pairing it with a subwoofer helps more than usual for a speaker this size. Measured bass extension of 61Hz (-3dB), with a measured sensitivity of 84dB.
Cons: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material: possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat. Vertical directivity is unusually tight for this class of speaker, holding together only within about ±5° of the tweeter axis before a real hole opens up in the response, so seating height matters a lot more than on most bookshelf designs. Diffraction artifacts around 3kHz and 5kHz show up as differences between the listening-window and on-axis curves. Distortion climbs well past acceptable levels at higher output: harmonic distortion exceeds 3% around 150Hz at 96dB (versus under 1% at 86dB), multitone distortion tops 10% at 96dB/1m, and real compression sets in between 96-102dB (about 1.5dB of lost dynamic range around 300Hz at 102dB/1m, roughly equivalent to 92dB for a pair at 4m in a room). A genuine limitation on how loud or how far away this speaker can be pushed. Measured average sensitivity (84dB) runs a few dB below the 87dB spec. Only a 5” woofer, so a subwoofer is required for real bass. 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.
