Short answer: the Genelec 8050B, on measurements. Its CEA2034 spinorama shows a very good on-axis response with excellent directivity, though a dip around 2kHz appears in both the on-axis and predicted in-room measurements. The 8040B is ranked on its smaller speaker’s performance and is very expensive.
On the Genelec 8040B side: Based on the smaller sibling’s measured performance against others, it is ranked accordingly. Set against that: Very expensive.
The case for the Genelec 8050B: CEA2034 spinorama shows a very good on-axis response with excellent directivity. The tradeoff: A dip around 2kHz shows up in both the on-axis and predicted in-room measurements.

Genelec 8040B: $2,790 per pair B&H Photo Video eBay
Pros: A compact professional monitor with balanced XLR input and analog room-adjustment controls. The manufacturer’s 41Hz limit is specified at -6dB, offering a useful reference for system planning without confusing it with a measured -3dB point.
Cons: It lacks GLM calibration and consumer streaming inputs. The balanced XLR connection may require an interface or controller for a typical desktop source.

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.
