Short answer: the KEF R11 Meta for bass depth, the JBL HDI-3600 for sensitivity and low midrange distortion. The JBL offers high 90dB sensitivity and very low midrange distortion, but a wide shelving-down above 2kHz affects its in-room response and its vertical dispersion is a bigger problem than horizontal, with a wider dip than on the HDI-1600. The KEF goes deeper, to an F10 of 30Hz, with only a dip around 1-1.2kHz.
Buy the KEF R11 Meta when sound quality outweighs the price for you, and the JBL HDI-3600 when the price outweighs sound quality instead.

KEF R11 Meta: $6,999.98 per pair Amazon eBay
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.

JBL HDI-3600: $3800 per pair Audio Advice eBay
Pros: CEA2034 spinorama shows a fairly even on-axis response and flat overall frequency response, with high 90dB sensitivity and very low distortion through the midrange. Triple 6.5” Advanced Aluminum Matrix woofers and a 1” compression driver in JBL’s HDI waveguide. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: A wide shelving-down above 2kHz affects the in-room response, and vertical dispersion is a bigger issue than horizontal: the reviewer noted the dip is wider here than on the smaller HDI-1600, making it more audible. Narrow vertical sweet spot means careful listener-height positioning matters more than usual.
