Short answer: the Revel Concerta2 F35, if you are buying new. The KEF R5 Meta ranks higher than it (#13 vs #24 of 89 floorstanding speakers, 4.6/5 vs 4.5/5) but is discontinued, so only consider it used; the Revel Concerta2 F35 is still sold new at $900.
Buy the Revel Concerta2 F35, since the KEF R5 Meta is discontinued and only worth hunting down used.

KEF R5 Meta: $3,999.99 per pair Discontinued eBay
Pros: 12th generation 5” Uni-Q coaxial driver array with Metamaterial Absorption Technology (MAT) delivers remarkably smooth, controlled horizontal (±50°) and vertical directivity with near-identical off-axis tracking. Exceptional frequency response linearity through the midrange and treble that takes extremely well to minor parametric EQ adjustments. Constrained Layer Damping cabinet construction and flexible rear ports minimize enclosure resonances and port turbulence. Deliberately tuned low-frequency roll-off profile permits boundary-adjacent room placement near front walls without boomy acoustic buildup. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Low-frequency extension (F3 of 52Hz, F10 of 38Hz) requires pairing with a dedicated subwoofer crossed over at 80Hz for high-output home theater or bass-heavy music performance. High-frequency radiation above 7kHz shows a mild on-axis taper (1-2dB downward slope), performing best when listened to 10-20° off-axis. Moderate sensitivity (~86dB SPL average) requires a clean, robust 4-ohm capable amplifier to drive high dynamic peaks without clipping. Discontinued.

Revel Concerta2 F35: $900 per pair Crutchfield eBay
Smaller model: the Revel Concerta2 M16 (rated 4.1/5).
Pros: Two-and-a-half-way, four-driver design: a 1” aluminum dome tweeter on a waveguide, a 5.25” mid-range, and dual 5.25” mid-bass drivers in a rear-ported cabinet. Measured sensitivity of 89.4dB closely matches the 90dB spec, and distortion looks good at both 86dB and 96dB, holding up well even with a high-pass filter applied. At its sale price of $900/pair, down from full retail, the reviewer calls it a “no-brainer,” undercutting comparable budget floorstanders like the ELAC DF63. Frequency response and directivity mismatches are largely EQ-able, since most of what shows up in measurements traces to physical tweeter/mid-range separation rather than a fundamental flaw. Compression is fairly well controlled for the price: about 1dB of loss around 100Hz under long-term compression, described as “par for the course” at this cost. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension. A dip in the lower midrange/2-3kHz region reduces attack and detail, and a peak around 5kHz adds some edge and sibilance in the lower treble. A peak in off-axis energy around 3kHz reflects off sidewalls at roughly 60-70° off-axis and arrives louder than the direct sound: this specific issue can’t be fixed with EQ (boosting the direct sound would boost the stronger reflection too) and would need acoustic absorption to properly address, though the reviewer considers it a minor, optional fix at this price. A couple of minor resonances appear in the impedance plot, including one around 300Hz that may partly explain a subtle sense of vocal warmth noticed in listening, though it’s more likely room-related. Minimum impedance around 3.8 ohms. Short-term compression testing shows some increased distortion in the tweeter and higher-frequency compression at loud output.
