Short answer: the Genelec 8351B for flatter on- and off-axis response, with a deep-bass caveat. Its CEA2034 spinorama is exceptionally flat both on and off axis, but deep bass distortion rises substantially at 96dB SPL/1m and the reviewer notes deep bass suffers below about 100Hz. The 8050B is very good on axis with excellent directivity, though a dip around 2kHz shows up on axis and in-room.
On the Genelec 8050B side: CEA2034 spinorama shows a very good on-axis response with excellent directivity. The catch: A dip around 2kHz shows up in both the on-axis and predicted in-room measurements.
The case for the Genelec 8351B: CEA2034 spinorama shows exceptionally flat response both on- and off-axis. The catch: Deep bass distortion rises substantially at higher output (96dB SPL/1m) - the reviewer notes “deep bass suffers” below about 100Hz.

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 68Hz (-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.

Genelec 8351B: $9150 per pair B&H Photo Video eBay
Pros: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Coaxial midrange and treble help maintain consistent sound as the listening angle changes. Low measured distortion at ordinary listening levels and GLM calibration make it a strong precision-monitoring choice. Measured bass extension of 33Hz (-3dB).
Cons: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material. Upper-treble distortion in the test also cautions against assuming unlimited output. Calibration hardware adds to an already expensive system, and the quoted result is for the measured vertical orientation.
