Short answer: the Dynaudio Emit M10 for measured distortion, the Wharfedale Diamond 12.1 for flatter voicing. The Emit M10 shows headphone-level distortion through the midrange and tweeter at 86dB SPL, but it is tuned to a mild showroom sound with boosted upper bass and treble and a recessed midrange. The Diamond 12.1 holds distortion under 1% THD down to about 60Hz, though its 3dB dip in the 1-3kHz crossover region 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 Philharmonic Ceramic Mini instead.

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

Dynaudio Emit M10: $800 per pair Discontinued eBay
Newer model: the Dynaudio Emit 10. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: CEA2034 spinorama shows impressive, headphone-level distortion through the midrange and tweeter at 86dB SPL, with a well-executed port that keeps resonance low below the crossover. 28mm soft dome tweeter and 14cm MSP mid/bass driver. Measured bass extension of 60.1Hz (-3dB), with a measured sensitivity of 83.5dB.
Cons: Tuned toward a mild showroom sound with boosted upper bass and treble and a recessed midrange: the reviewer prefers speakers that get the 100Hz-3kHz range right, which this doesn’t. His verdict: cheaper speakers deliver much more balanced tonality, so he wouldn’t buy it for himself. Discontinued.
