Short answer: the Genelec 8351B for better sound quality, the Adam Audio T8V for the lower price. The Genelec 8351B ranks #4 of 113 powered bookshelf speakers, rated 4.8/5, at $9,900. The Adam Audio T8V ranks #92, rated 3.9/5, at $599.98, $9,300.02 cheaper.
Why pick the Adam Audio T8V: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. The tradeoff: The 6.31 ideal-subwoofer score and 3.0dB response span from 300Hz to 5kHz show less even tonal balance than stronger budget alternatives.
The Genelec 8351B is the better-sounding, deeper-bass option. The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Its bass reaches about 33Hz before falling 3dB, against 39.6Hz for the Adam Audio T8V. The catch: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material.
Buy the Adam Audio T8V if the price matters more than sound quality. Buy the Genelec 8351B if sound quality matters more than the price.

Adam Audio T8V: $599.98 per pair Amazon eBay
Same family: the Adam Audio T5V (smaller bookshelf, rated 4/5) and the Adam Audio T7V (smaller bookshelf, ranked lower, rated 3.9/5).
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. Measured bass extension of 39.6Hz (-3dB).
Cons: The 6.31 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. A notch around 4.6kHz, where tweeter and woofer interact, and a hole below the tweeter axis mean the tweeter should sit at or above ear height.

Genelec 8351B: $9,900 per pair B&H Photo Video eBay
Older model: the Genelec 8351A (ranked lower, estimated 4.6/5).
Same family: the Genelec 8331A (smaller bookshelf, rated 4.8/5), the Genelec 8341A (smaller bookshelf, ranked lower, rated 4.8/5), the Genelec 8361A (larger bookshelf, ranked lower, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5).
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.
