Short answer: the HEDD Type 20 MK2 if sound quality matters most, the Adam Audio T8V if price matters most. The HEDD Type 20 MK2 ranks #26 of 113 powered bookshelf speakers, rated 4.5/5, at $4,798. The Adam Audio T8V ranks #92, rated 3.9/5, at $719.98, $4,078.02 cheaper.
What the Adam Audio T8V does well: Measured -3dB extension of 39.6Hz gives useful bass depth for an affordable large monitor. The catch: 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 HEDD Type 20 MK2 is the more accurate, deeper-bass option. The measured ported configuration reaches 35.2Hz at -3dB and scores 7.69 with an ideal subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 6.11 against 4.65 for the Adam Audio T8V. Its bass reaches about 32Hz before falling 3dB, against 39.6Hz for the Adam Audio T8V. The tradeoff: These results are for ported operation, not every bass or phase setting.
Buy the Adam Audio T8V if the price is the priority over sound quality, or the HEDD Type 20 MK2 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.

HEDD Type 20 MK2: $4,798 per pair B&H Photo Video eBay
Pros: The measured ported configuration reaches 35.2Hz at -3dB and scores 7.69 with an ideal subwoofer. A 2.4dB response span from 300Hz to 5kHz supports broadly balanced mids, while ported operation reduces deep-bass strain compared with the sealed setting in the review. Measured bass extension of 32Hz (-3dB).
Cons: These results are for ported operation, not every bass or phase setting. Horizontal asymmetry and vertical crossover behavior make orientation and listening position important. Distortion rises at higher output, and linear-phase processing can add latency for live monitoring.
