Short answer: the Kii THREE on measured sound quality, the Adam Audio T8V on price. The Kii THREE ranks #3 of 113 powered bookshelf speakers, rated 4.9/5, at $16,970. The Adam Audio T8V ranks #92, rated 3.9/5, at $719.98, $16,250.02 cheaper.
Why pick the Adam Audio T8V: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. Watch for: 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 Kii THREE is the more accurate, deeper-bass pick. Exceptionally even measured balance: the 300Hz-5kHz response spans only 1.2dB, with preference scores of 7.70 standalone and 8.35 with an ideal subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 7.70 against 4.65 for the Adam Audio T8V. Its bass reaches about 28Hz before falling 3dB, against 39.6Hz for the Adam Audio T8V. The tradeoff: Deep-bass output has limits: demanding low-frequency material at high levels can trigger compression or audible distress.
Buy the Adam Audio T8V if the price is the priority over sound quality, or the Kii THREE if sound quality is the priority over the price.

Adam Audio T8V: $719.98 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.

Kii THREE: $16,970 per pair Vintage King eBay
Same family: the Kii Seven (smaller bookshelf, ranked lower, estimated 4.6/5).
Pros: Exceptionally even measured balance: the 300Hz-5kHz response spans only 1.2dB, with preference scores of 7.70 standalone and 8.35 with an ideal subwoofer. Cardioid control reduces rearward low-midrange energy, while measured -3dB extension of 29.3Hz provides convincing full-range bass in a compact system. Measured bass extension of 28Hz (-3dB).
Cons: Deep-bass output has limits: demanding low-frequency material at high levels can trigger compression or audible distress. The reviewer preferred a small treble reduction, so the high score is not a promise of ideal tonal balance for every listener. Linear-phase operation adds latency, and the system is expensive.
