Short answer: both are discontinued, so this only matters if you are buying used. Used, the Wharfedale Diamond 12.1 is the better pick: it ranks #32 of 179 bookshelf speakers by sound quality (rated 3.9/5), against #161 (rated 2.1/5) for the JBL Stage A130. If you want one new, the Wharfedale Diamond 12.1i replaces the Wharfedale Diamond 12.1 and is rated 4.0/5 at $499.
The Wharfedale Diamond 12.1 is the more accurate option. Smooth, easy listening budget bookshelf speakers with low distortion, wide dispersion and a fit and finish above their class. Its measured preference score, a predictor of how neutral it sounds, is 5.01 against 4.04 for the JBL Stage A130. The tradeoff: 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, relaxed 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: A discontinued bookshelf speaker with an aluminum tweeter and wide, consistent dispersion through the midrange. The tradeoff: Still shows the same underlying response shape as the JBL Stage 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.
Buy the Wharfedale Diamond 12.1 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Wharfedale Diamond 12.1i, which replaces the Wharfedale Diamond 12.1.

Measured Differences
- Tonal accuracy above the bass: with a subwoofer taking the low end, the Wharfedale Diamond 12.1 scores 7.4 against 6.5 for the JBL Stage A130 on the Spinorama preference scale. Its frequency response and off-axis sound are smoother, so voices and instruments sound closer to the recording.
- Close enough not to matter: bass extension (46 Hz vs 50 Hz, 10 dB down).
