Short answer: the JBL Stage 250B. Both are rated 3.2/5 for sound quality (#91 and #95 of 168 bookshelf speakers), and the JBL Stage 250B costs $349.95 against $399 for the Wharfedale Diamond 12.0i, so with nothing between them on sound quality, price settles it.
The case for the JBL Stage 250B: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The tradeoff: Its objective score is good rather than class-leading, and the rear port needs some wall clearance.
What the Wharfedale Diamond 12.0i does well: The 2025 update of the Wharfedale Diamond 12.0, keeping its 4” Klarity woofer and 1” woven polyester dome tweeter with a refined port, extra bracing and damping. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the JBL Stage 250B. Both are rated the same for sound quality, and it costs $49.05 less than the Wharfedale Diamond 12.0i.
About the ratings: the Wharfedale Diamond 12.0i’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.9 to 3.5, so this verdict could change once it is measured.

Older models: the JBL Arena 120 (ranked higher, rated 3.8/5) and the JBL Stage A130 (ranked lower, rated 2.1/5). See every JBL Arena and Stage generation.
Same family: the JBL Stage 2 240B (smaller bookshelf, ranked lower, estimated 2.7/5), the JBL Stage 2 260F (smaller floorstanding, estimated 4.2/5), the JBL Stage 2 280F (larger floorstanding, rated 3.4/5), the JBL Stage 2 245C (center, estimated 3.2/5), the JBL Stage 200P (smaller subwoofer, estimated 3.5/5) and the JBL Stage 220P (larger subwoofer, estimated 3.7/5).
Pros: Good local Spinorama scores of 4.06 raw and 6.60 with a subwoofer, with smooth horizontal directivity from JBL’s next-generation HDI waveguide. The current Stage 2 model offers solid build details, magnetic grilles and useful 56Hz measured extension at an accessible price. Measured bass extension of 64.5Hz (-3dB).
Cons: Its objective score is good rather than class-leading, and the rear port needs some wall clearance. At 86dB sensitivity and six-ohm nominal impedance it is not especially easy to drive, while the compact woofer limits deep-bass output.

Wharfedale Diamond 12.0i: $399 per pair Estimated Music Direct eBay
Older model: the Wharfedale Diamond 12.0 (ranked lower, estimated 3.1/5). See every Wharfedale Diamond generation.
Same family: the Wharfedale Diamond 12.1i (larger bookshelf, ranked higher, estimated 4/5), the Wharfedale Diamond 12.3i (smaller floorstanding, estimated 4/5), the Wharfedale Diamond 12.4i (larger floorstanding, estimated 4.2/5) and the Wharfedale Diamond 12.Ci (center, estimated 3.6/5).
Pros: The 2025 update of the Wharfedale Diamond 12.0, keeping its 4” Klarity woofer and 1” woven polyester dome tweeter with a refined port, extra bracing and damping. At 87dB and 8 ohms it is easy to drive from a small amplifier, and it is the most compact model in Wharfedale’s Diamond 12i range.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. Rated bass stops at 70Hz (±3dB), so it needs a subwoofer for anything beyond desktop or small-room listening.
