Short answer: the KEF R11 Meta, because the R5 Meta needs a subwoofer for the bass the R11 delivers on its own. The R11’s spinorama is generally flat on-axis with very deep bass to an F10 of 30Hz, though a dip around 1-1.2kHz shows in the predicted in-room response. The R5 Meta’s 5” Uni-Q array tracks near-identically off-axis at about +/-50 degrees, but its F3 of 52Hz and F10 of 38Hz mean a subwoofer is needed at 80Hz.
Buy the KEF R11 Meta new; the KEF R5 Meta is no longer sold new, so it only makes sense as a used find.

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.

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.
