Short answer: it depends which flaw you can live with. The Diamond 220’s on-axis response is smooth once the grille comes off, which Amir called a huge improvement over the stock grille’s comb filtering around 5kHz, but it rolls off below 200Hz and wants a subwoofer. The Diamond 12.1 holds distortion under 1% THD to about 60Hz, with a 3dB dip in the 1-3kHz crossover region that saps attack.
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, start with the Ascend Acoustics HTM-200SE2 instead.

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.

Wharfedale Diamond 220: $299 per pair Discontinued eBay
Newer model: the Wharfedale Diamond 12.1i. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: Amir found the on-axis response smooth once the grille is removed, calling grille removal “a huge improvement” since the stock grille caused unusually strong comb filtering around 5kHz. Good horizontal dispersion from the waveguide-loaded tweeter and controlled distortion. After some EQ (a room mode filter and treble shelf), the reviewer called it “a truly hifi speaker” where “every audiophile track..sounded very good,” and said he was “happy to recommend” it for the budget class. Measured bass extension of 117.2Hz (-3dB), with a measured sensitivity of 86.9dB.
Cons: Response rolls off below 200Hz, so a subwoofer is recommended for full-range use. Some port rattling was noted at high volumes, traced to vibration rather than the woofer itself. Best performance requires removing the grille and applying the reviewer’s EQ filters. Discontinued, with only limited remaining stock available direct from Wharfedale.
