Short answer: the Wharfedale Diamond 12.1 for better sound quality, the Wharfedale Diamond 220 for the lower price. The Wharfedale Diamond 12.1 ranks #13 of 56 bookshelf speakers at $599. The Wharfedale Diamond 220 ranks #19 at $350, $249 cheaper.
On the Wharfedale Diamond 12.1 side: 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. Set against that: 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.
The case for the Wharfedale Diamond 220: 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. The tradeoff: Response rolls off below 200Hz, so a subwoofer is recommended for full-range use.
Buy the Wharfedale Diamond 12.1 if sound quality matters more than the price. Buy the Wharfedale Diamond 220 if the price matters more than sound quality.

The Two Speakers In Full
Wharfedale Diamond 12.1: $599 Discontinued
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.
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: $350 Amazon
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.
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.
