Short answer: the Wharfedale Diamond 12.1 for out-of-box balance, the Paradigm Monitor SE Atom for EQ-friendly directivity. The Atom’s consistent directivity makes it easier to equalize and less room-dependent, but its on-axis response has a 2-4kHz dip then a peak and a 15kHz resonance that give it a bright showroom voicing. The Diamond 12.1 holds distortion under 1% THD to about 60Hz, though its 1-3kHz dip saps attack.
Buy the Paradigm Monitor SE Atom, since the Wharfedale Diamond 12.1 is discontinued and only worth hunting down used.

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.

Paradigm Monitor SE Atom: $399.98 per pair Paradigm eBay
Pros: Good, consistent directivity across the on-axis, listening-window, and off-axis curves makes the Atom easier to equalize and less room-dependent than many budget speakers. Bass tuning is well judged, letting the woofer play loud on demanding tracks without bottoming out even without a subwoofer. Paradigm’s NRC research pedigree shows in the horizontal and vertical dispersion measurements. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 85dB.
Cons: On-axis response is uneven out of the box, with a 2-4kHz dip followed by a peak and a resonance around 15kHz that the reviewer said gives it a bright, “showroom” voicing without EQ correction. There’s no meaningful bass extension for full-range use, so a subwoofer is effectively required for anything beyond desktop or near-field listening.
