Short answer: the Genelec 8331A on measured sound quality, the Focal Alpha 50 EVO on price. The Genelec 8331A ranks #1 of 105 powered bookshelf speakers, rated 4.8/5, at $5,750. The Focal Alpha 50 EVO ranks #52, rated 3.8/5, at $658, $5,092 cheaper.
The case for the Focal Alpha 50 EVO: Rear shelving controls and a conventional studio-monitor layout provide practical placement adjustment. The tradeoff: Basic shelving controls are less flexible than parametric room correction.
The Genelec 8331A is the more accurate choice. Erin’s Klippel measurements support its reference-monitor credentials: a 1.4dB response span from 300Hz to 5kHz, low listening-window and predicted-room irregularity, and preference scores of 6.57 standalone and 8.51 with an ideal subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 6.57 against 1.04 for the Focal Alpha 50 EVO. The catch: Expensive, with studio-oriented XLR connectivity rather than consumer streaming.
Buy the Focal Alpha 50 EVO if the price is the priority over sound quality, or the Genelec 8331A if sound quality is the priority over the price.

Same family: the Focal Alpha 65 EVO (larger bookshelf, rated 4/5), the Focal Alpha 80 Evo (larger bookshelf, estimated 4/5) and the Focal Alpha Twin Evo (larger bookshelf, rated 3.8/5).
Pros: Rear shelving controls and a conventional studio-monitor layout provide practical placement adjustment.

Genelec 8331A: $5,750 per pair B&H Photo Video eBay
Same family: the Genelec 8341A (larger bookshelf, rated 4.8/5), the Genelec 8351B (larger bookshelf, rated 4.8/5), the Genelec 8361A (larger bookshelf, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5). See every Genelec 8351 and The Ones generation.
Pros: Erin’s Klippel measurements support its reference-monitor credentials: a 1.4dB response span from 300Hz to 5kHz, low listening-window and predicted-room irregularity, and preference scores of 6.57 standalone and 8.51 with an ideal subwoofer. The coaxial mid/tweeter and concealed woofers maintain coherent radiation as listening position changes. Bass reaches -3dB around 48Hz, and GLM adds level, delay and room-response calibration. Measured bass extension of 49Hz (-3dB).
Cons: Expensive, with studio-oriented XLR connectivity rather than consumer streaming. The compact woofers still limit deep-bass output, and the review reports protection muting when pushed beyond its operating range. GLM calibration hardware is an additional purchase. Its excellent tonal score does not remove the need for a subwoofer or larger monitor at demanding levels.
