Short answer: the KEF R11 Meta for better sound quality, the Focal Aria Evo X N°2 for the lower price. The KEF R11 Meta ranks #26 of 68 floorstanding speakers at $3499.99. The Focal Aria Evo X N°2 ranks #58 at $2399, $1100.99 cheaper.
What the KEF R11 Meta offers: 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. Watch for: 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.
What the Focal Aria Evo X N°2 offers: Solid bass with a deliberate mid-bass bump (80-120Hz) that gives extra thump and weight, extending to about 40-50Hz in-room. High sensitivity (measured 88.2dB) makes it easy to drive, and distortion is low throughout the range even at high output - the reviewer found only a minor compression “glare” around 4.5kHz at very high volumes, not a real concern. Directivity components (mid-range and tweeter) transition smoothly rather than abruptly, and the overall soundstage is wide and enveloping. Watch for: Sounds very bright pointed directly at the listener - the tweeter comes in 5-6dB above the midrange with an unusually wide, roughly two-octave dip (1kHz-4kHz) leading into it, giving a laid-back, low-attack character even after toeing out ~20 degrees. Fixing this properly requires real EQ (a mini DSP or similar), not just toe-out or absorption alone; without EQ, expect it to sound bright for stereo listening. A mild dip around 200Hz makes male vocals sound slightly subdued. Narrow vertical directivity (about +/-15 degrees) means you need to stay close to tweeter-axis height. Impedance dips to 3.4 ohms (EPDR 1.4 ohms), so it wants a 4-ohm-capable amplifier, and requires a plinth for floor clearance since it’s bottom-ported.
Buy the KEF R11 Meta if sound quality matters more than the price. Buy the Focal Aria Evo X N°2 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Focal Aria Evo X N°2. It ranks near the bottom of the 68 floorstanding speakers, so look higher up the list instead.
