Short answer: the KEF R11 Meta for deep bass, the JBL HDI-3800 for output and dynamics. The R11 Meta’s spinorama is generally flat with good directivity and very deep bass down to an F10 of 30Hz, though a dip around 1-1.2kHz attributed to diffraction shows in the predicted in-room response. The HDI-3800’s compression driver and HDI horn deliver exceptional horizontal directivity, high output and effortless transients, with a narrow 8-10kHz elevation as its catch.
Buy the KEF R11 Meta if you want one new; the JBL HDI-3800 is discontinued, so only look for it used.

Pros: 2410H-2 1” Teonex compression driver matched to a custom High-Definition Imaging (HDI) horn geometry achieves exceptional horizontal directivity control, high output capability, and effortless transient response. Triple 8” Advanced Aluminum Matrix woofers deliver deep, authoritative bass extension down to an F3 of 37Hz and F10 of 28Hz with minimal low-frequency compression. Outstanding sensitivity (92dB SPL at 2.83V/1m) and ultra-low THD/multitone distortion allow extremely high undistorted SPL output in large home theater spaces. Measured bass extension of 37Hz (-3dB), with a measured sensitivity of 92dB.
Cons: On-axis frequency response features a narrow upper-frequency elevation around 8-10kHz, performing noticeably smoother when toed out 10-20° off-axis. Vertical directivity handoff across the triple woofer layout creates vertical soundstage height tilt depending on listening distance and ear height. Minimum impedance dips to 3.8 ohms, requiring high-current amplifier stability. Substantial cabinet dimensions and 38kg weight require significant room real estate. Discontinued.

KEF R11 Meta: $6,999.98 per pair Amazon eBay
Smaller models: the KEF R7 Meta (ranked higher, estimated 4.6/5) and the KEF R3 Meta (rated 4.6/5).
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.
