Short answer: the KEF R3 for low-distortion three-way output, the Focal Aria 906 for dispersion at moderate levels. The R3 is a true three-way with sub-1% distortion at 86dB, orderly directivity in both planes and a measured -10dB point of 35.2Hz, though its bass rolls off gradually and an 80Hz subwoofer crossover makes sense. The Aria 906 matches with good horizontal dispersion of about 60 degrees and low woofer distortion at 86dB, but a 3dB dip around 2.8kHz and distortion that becomes a problem at 96dB. The Focal Aria 906 is discontinued; its replacement is the Focal Aria Evo X N°1.
Buy the KEF R3. It is rated higher for sound quality and still sold new, while the Focal Aria 906 is discontinued.
