Short answer: the KEF LS50 Wireless II for better sound quality, the Focal Alpha 50 EVO for the lower price. The KEF LS50 Wireless II ranks #18 of 100 powered bookshelf speakers, rated 4.3/5, at $2,999. The Focal Alpha 50 EVO ranks #51, rated 3.8/5, at $658, $2,341 cheaper.
What the Focal Alpha 50 EVO does well: Rear shelving controls and a conventional studio-monitor layout provide practical placement adjustment. The catch: Basic shelving controls are less flexible than parametric room correction.
The KEF LS50 Wireless II is the more accurate option. Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.43 against 1.04 for the Focal Alpha 50 EVO. It keeps a wired aux input, which the Focal Alpha 50 EVO lacks. Watch for: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Buy the Focal Alpha 50 EVO if the price matters more than sound quality. Buy the KEF LS50 Wireless II if sound quality matters more than the price.

KEF LS50 Wireless II: $2,999.00 per pair Amazon KEF Crutchfield eBay
Same family: the KEF LSX II LT (smaller bookshelf, ranked lower, rated 4/5), the KEF LSX II (smaller bookshelf, estimated 4.1/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.
