Short answer: the LOGProfessional Alpha. It ranks #14 of 68 powered bookshelf speakers by sound quality (rated 4.6/5); the Genelec 8050B ranks #27 (rated 4.4/5).
What the LOGProfessional Alpha does well: Sound & Recording’s measurements show a 1.2dB response span from 300Hz to 5kHz and a 8.26 ideal-subwoofer score. The catch: The measured -3dB point is 67.1Hz, making a subwoofer important for full-range listening.
What the Genelec 8050B does well: Measured -3dB extension of 35.2Hz gives the 8050B deeper native bass than many similarly ranked monitors. The tradeoff: A 2.7dB response span from 300Hz to 5kHz and a dip around 2kHz keep it below the strongest tonal performers.
Buy the LOGProfessional Alpha. It is rated higher for sound quality than the Genelec 8050B.

LOGProfessional Alpha: €11,560 per pair LOGProfessional eBay
Pros: Sound & Recording’s measurements show a 1.2dB response span from 300Hz to 5kHz and a 8.26 ideal-subwoofer score. This supports a particularly even midrange and makes the Alpha a promising choice for a system with properly integrated bass support.
Cons: The measured -3dB point is 67.1Hz, making a subwoofer important for full-range listening. A smooth midrange is not proof of high clean output or uniformly controlled dispersion.

Genelec 8050B: $3800 per pair B&H Photo Video eBay
Pros: Measured -3dB extension of 35.2Hz gives the 8050B deeper native bass than many similarly ranked monitors. The 6.49 ideal-subwoofer score supports broadly balanced listening, with a waveguide and analog boundary controls for practical studio placement. Measured bass extension of 35.2Hz (-3dB).
Cons: A 2.7dB response span from 300Hz to 5kHz and a dip around 2kHz keep it below the strongest tonal performers. Port-related response features and high-level distortion also warrant attention. Unlike the SAM models, it does not provide GLM room calibration.
