Short answer: the Ascend Acoustics Sierra Titan Tower. Both are rated 4.4/5 for sound quality (#45 and #46 of 226 floorstanding speakers), and the Ascend Acoustics Sierra Titan Tower costs $2,998 against $6,999.98 for the KEF R11 Meta, so with nothing between them on sound quality, price settles it.
Why pick the Ascend Acoustics Sierra Titan Tower: A SEAS Titan dome tweeter and dual 5.25 inch long throw woofers in a bamboo V-LAM tower reach a measured 58.6Hz extension point at a more accessible price than Ascend’s ribbon tweeter ELX line. Watch for: Its listening window response is the least smooth of Ascend’s measured towers, trailing the pricier Ascend Acoustics ELX Ribbon Tower.
The case for the KEF R11 Meta: CEA2034 spinorama shows a generally flat on-axis response with good directivity and very deep bass extension (F10 of 30Hz). The tradeoff: 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.
Buy the Ascend Acoustics Sierra Titan Tower. Both are rated the same for sound quality, and it costs $4,001.98 less than the KEF R11 Meta.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

Same family: the Ascend Acoustics Sierra 1 v2 (smallest bookshelf, rated 4.7/5), the Ascend Acoustics Sierra-2EX V2 (bookshelf, rated 4.3/5), the Ascend Acoustics Sierra-LX (largest bookshelf, rated 4.3/5) and the Ascend Acoustics Sierra Horizon V2 (center, estimated 4.3/5). See every Ascend Sierra generation.
Pros: A SEAS Titan dome tweeter and dual 5.25 inch long throw woofers in a bamboo V-LAM tower reach a measured 58.6Hz extension point at a more accessible price than Ascend’s ribbon tweeter ELX line. The bass alignment Q of 0.72 keeps the low end reasonably well controlled. Backed by the same 7 year parts and labor warranty and hand matched +/-1.5dB pairs, each shipped with its own production line frequency response printout. Measured bass extension of 58.6Hz (-3dB).
Cons: Its listening window response is the least smooth of Ascend’s measured towers, trailing the pricier Ascend Acoustics ELX Ribbon Tower. Sound power response falls off more steeply above the crossover than the ribbon version, so off axis and in room treble energy rolls off faster. Ascend sells direct only, with no dealer network or third party retailers for an in person audition.

KEF R11 Meta: $6,999.98 per pair Amazon $3,499.99 eBay
Older model: the KEF R11 (ranked lower, estimated 4.3/5). See every KEF R Series generation.
Same family: the KEF R3 Meta (bookshelf, rated 4.6/5), the KEF R5 Meta (smaller floorstanding, ranked higher, rated 4.6/5), the KEF R7 Meta (smaller floorstanding, ranked higher, estimated 4.6/5), the KEF R2 Meta (smaller center, rated 4.3/5) and the KEF R6 Meta (larger center, rated 4.2/5).
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.
