Short answer: the Genelec 8040B on measured sound quality, the Adam Audio T8V on price. The Genelec 8040B ranks #32 of 67 powered bookshelf speakers at $2350. The Adam Audio T8V ranks #53 at $349.99, $2000.01 cheaper.
What the Adam Audio T8V offers: Quite balanced and neutral, very close to the Yamaha HS8. Deeper bass than the HS8 Watch for: A crossover-region notch around 4.6kHz where tweeter and woofer interact, and a hole in the vertical response below the tweeter axis - keep the tweeter at or above ear height. Distortion is well controlled at 86dB SPL but gets messier at 96dB.
What the Genelec 8040B offers: Based on their smaller speaker’s performance against others, I’m ranking this accordingly. Watch for: Very expensive
Buy the Adam Audio T8V when the price outweighs sound quality for you, and the Genelec 8040B when sound quality outweighs the price instead.
The Adam Audio T8V is not a sound-quality pick. It sits near the bottom of the 67 powered bookshelf speakers; there are better options higher up.

Adam Audio T8V: $349.99 Amazon eBay
Pros: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. Analog inputs and basic shelf controls offer uncomplicated studio integration.
Cons: The 5.42 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives. Treble emphasis and crossover-region vertical cancellation make listening height important. Deep bass and an AMT tweeter do not by themselves imply accurate sound.

Genelec 8040B: $2350 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.
