Short answer: the KEF Reference 203 on measurements, if condition holds up. It delivers on-axis linearity within about +/-3dB and genuinely good directivity, roughly 55 degrees horizontally and 40-50 degrees vertically, but it is 20+ years old, long-discontinued and secondhand only. The Revel F206 measures a pretty even on-axis response, though some directivity error around 3kHz and a small peak around 4.5kHz show up alongside it.
Buy the KEF Reference 203 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 MoFi SourcePoint 888 instead.

KEF Reference 203: $5,000 per pair Discontinued eBay
Newer model: the KEF Reference 3 Meta, ranked lower, rated 4.6/5.
Pros: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees), and an estimated in-room response that closely matches what the reviewer actually heard. Distortion is excellent: under 1% harmonic above 80Hz at both 86dB and 96dB, and multitone stays around 1% even at 96dB. Bass reaches a real F3 of 51Hz (F10 37Hz), with in-room extension into the low-mid-40s. The reviewer’s overall listening notes were essentially “nothing stood out bad or good”: a genuinely neutral, accurate speaker with a distinctive rounded-baffle look that avoids the diffraction issues a flat baffle this wide would normally have. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 88dB.
Cons: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums): condition, driver matching, and component aging vary by unit, so audition before buying if at all possible. Demands a robust amplifier: impedance dips to about 3.6 ohms with an EPDR of 2.2 ohms. The small supertweeter shows minor breakup artifacts at the extremes of the vertical polar plot and some compression at very high output in the top octave, though neither was audible in normal listening.

Revel F206: $2,000 per pair used Discontinued eBay
Newer model: the Revel F226Be, ranked higher, rated 4.6/5.
Pros: CEA2034 spinorama shows a pretty even on-axis response. Predicted in-room response is excellent, with a smooth downward slope. Horizontal beamwidth of about ±65 degrees is wide, if a bit uneven. Distortion is very nice at 86dB SPL/1m, falling below the frequency range where human hearing is most sensitive, and stays excellent even at 96dB SPL/1m. Near-field measurements of the individual drivers show nice suppression of port and woofer resonances. Really amazing value for the performance. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 87dB.
Cons: Some directivity error and a small peak around 4.5kHz show up alongside the directivity error around 3kHz. Vertical directivity means listening position needs to stay within the tweeter axis, though the reviewer notes there is some leeway. Minimum impedance dips to 3.3 ohms, calling for an amplifier comfortable with a demanding load. Discontinued.
