Short answer: the Q Acoustics 5040, if you are buying new. The KEF R5 Meta ranks higher than it (#14 vs #97 of 188 floorstanding speakers, 4.6/5 vs 4.1/5) but is discontinued, so only consider it used; the Q Acoustics 5040 is still sold new at $4,014.96.
The case for the Q Acoustics 5040: C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. Watch for: Free-field frequency response exhibits a noticeable mid-bass scoop around 200Hz (~6dB lower than mean SPL), causing an F3 of 70Hz (F10 of 39Hz) in open space and requiring boundary placement (11-22 inches from front wall) to reinforce upper bass output.
The KEF R5 Meta is the more accurate, deeper-bass choice. 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. Its measured preference score, a predictor of how neutral it sounds, is 6.33 against 3.80 for the Q Acoustics 5040. Its bass reaches about 52Hz before falling 3dB, against 70Hz for the Q Acoustics 5040. Watch for: 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.
Buy the Q Acoustics 5040 new; the KEF R5 Meta is no longer sold new, so it only makes sense as a used find.

Q Acoustics 5040: $4,014.96 per pair Amazon eBay
Same family: the Q Acoustics 5010 (smaller bookshelf, estimated 3.5/5), the Q Acoustics 5020 (larger bookshelf, rated 2.2/5), the Q Acoustics 5050 (larger floorstanding, ranked higher, estimated 4.3/5) and the Q Acoustics 5090 (center, estimated 3.7/5).
Pros: C3 (Continuous Curved Cone) driver profile technology provides smooth midrange integration, controlled cone breakup, and improved bass damping. High voltage sensitivity (91.5dB SPL at 2.83V/1m) allows loud listening with low-to-moderate amplifier wattage. Cabinet features Point-to-Point (P2P) internal bracing and Helmholtz Pressure Equalizer (HPE) tubes to suppress internal standing waves and panel vibrations. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 91.5dB.
Cons: Free-field frequency response exhibits a noticeable mid-bass scoop around 200Hz (~6dB lower than mean SPL), causing an F3 of 70Hz (F10 of 39Hz) in open space and requiring boundary placement (11-22 inches from front wall) to reinforce upper bass output. Measurements indicate an enclosure resonance near 300Hz visible in sound power data. Minimum impedance drops to 3.0 ohms, demanding a stable 4-ohm rated amplifier despite high sensitivity.

KEF R5 Meta: $3,999.99 per pair Discontinued eBay
Same family: the KEF R3 Meta (bookshelf, rated 4.6/5), the KEF R7 Meta (larger floorstanding, ranked lower, estimated 4.6/5), the KEF R11 Meta (larger floorstanding, ranked lower, rated 4.4/5), the KEF R2 Meta (smaller center, rated 4.3/5) and the KEF R6 Meta (larger center, rated 4.2/5).
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.
