Short answer: the Ascend Acoustics Sierra Titan Tower. Both are rated 4.4/5 for sound quality (#45 and #46 of 228 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: Accurate floorstanding speakers with a premium tweeter and controlled bass, hand matched pairs and a long seven year warranty. 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: Slim floorstanding speakers with accurate sound, very deep bass and extremely low distortion even when played loud, with excellent coaxial imaging. 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.
