Short answer: the Genelec 8340A, if you are buying new. The Genelec 8040B ranks higher than the Adam Audio T8V (#54 vs #92 of 113 powered bookshelf speakers) but is discontinued; its replacement, the Genelec 8340A, is rated 4.4/5 at $3,790 and is still sold new.
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 Genelec 8040B is the better-sounding choice. A compact professional monitor with balanced XLR input and analog room-adjustment controls. The catch: It lacks GLM calibration and consumer streaming inputs.
Buy the Genelec 8340A, the replacement for the discontinued Genelec 8040B; it is rated higher for sound quality than the Adam Audio T8V.

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 8040B: $2,790 per pair Discontinued B&H Photo Video eBay
Newer model: the Genelec 8340A, ranked higher, estimated 4.4/5. It uses the same cabinet and woofer size, adding GLM room calibration and an AES/EBU digital input.
Same family: the Genelec 8010A (smaller bookshelf, rated 4.5/5), the Genelec 8020D (smaller bookshelf, rated 4.4/5), the Genelec 8030C (smaller bookshelf, rated 4.6/5) and the Genelec 8050B (larger bookshelf, ranked higher, rated 4.4/5).
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. It is expensive. Discontinued.
