Short answer: the KEF R11 Meta for bass depth; the Revel F206 is similarly even but gives up extension. The F206’s spinorama shows a pretty even on-axis response, but some directivity error and a small peak around 4.5kHz appear alongside the directivity error around 3kHz. The KEF is generally flat on-axis with good directivity and very deep bass extension to an F10 of 30Hz, with a small dip around 1-1.2kHz as its main flaw.
What the KEF R11 Meta gets right: CEA2034 spinorama shows a generally flat on-axis response with good directivity and very deep bass extension (F10 of 30Hz). Set against that: A dip around 1-1.2kHz on-axis is attributed to a diffraction effect, and shows up as a smaller dip in the predicted in-room response.
On the Revel F206 side: CEA2034 spinorama shows a pretty even on-axis response. The tradeoff: Some directivity error and a small peak around 4.5kHz show up alongside the directivity error around 3kHz.
Buy the KEF R11 Meta if you want one new; the Revel F206 is discontinued, so only look for it used.

Pros: CEA2034 spinorama shows a generally flat on-axis response with good directivity and very deep bass extension (F10 of 30Hz). Predicted in-room response is very smooth aside from the small 1-1.5kHz dip. The coaxial Uni-Q driver gives excellent, symmetric vertical directivity, unusual for a tower speaker. Distortion is incredibly low even down to 30Hz at 86dB SPL/1m, and stays low even at 96dB and 102dB SPL/1m - the reviewer found essentially no audible tonality change across that whole output range. Measured bass extension of 64Hz (-3dB).
Cons: A dip around 1-1.2kHz on-axis is attributed to a diffraction effect, and shows up as a smaller dip in the predicted in-room response. Horizontal beamwidth of about ±40 degrees is on the narrower side, though the transition from wide to constant directivity is smooth. Minimum impedance dips to 3.2 ohms around 580Hz, calling for an amplifier comfortable with a demanding load. 4-ohm nominal impedance overall.

Revel F206: $2000 per pair used, Discontinued eBay
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.
