Short answer: the Genelec 8050B for the higher ranking, the Genelec 8040B for the lower price. The Genelec 8050B ranks #6 of 20 powered bookshelf speakers at $3800. The Genelec 8040B ranks #7 at $2350, $1450 cheaper.
On the Genelec 8040B side: Based on their smaller speaker’s performance against others, I’m ranking this 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.
Buy the Genelec 8040B if the price matters more than the ranking. Buy the Genelec 8050B if the ranking matters more than the price.

Genelec 8050B: $3800 Bhphotovideo
Pros: CEA2034 spinorama shows a very good on-axis response with excellent directivity. Predicted in-room response is smooth, with only a 2kHz dip as a real issue. Horizontal beamwidth of about ±50 degrees is very smooth and well controlled. Vertical directivity is similarly even outside the 2kHz region, as long as listening position stays within about ±20 degrees of the woofer’s border. Distortion at 96dB SPL/1m is typical low-frequency behavior with the rest of the range well controlled.
Cons: A dip around 2kHz shows up in both the on-axis and predicted in-room measurements. An unexplained distortion spike appears around 10-15kHz at 96dB SPL/1m that the reviewer couldn’t identify a clear cause for. Cumulative spectral decay (waterfall) shows a port resonance lingering in the upper-bass/lower-midrange region. Very expensive.
