Short answer: the Adam Audio T8V, if you are buying new. The Thomann Swissonic A306 ranks higher than it (#31 vs #54 of 68 powered bookshelf speakers, 4.3/5 vs 3.9/5) but is discontinued, so only consider it used; the Adam Audio T8V is still sold new at $719.98.
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.
What the Thomann Swissonic A306 does well: With the treble control set to -2dB, Erin measured a 7.29 ideal-subwoofer score and 43.9Hz -3dB bass extension. The catch: The published result is not the flat-control setting: it specifically uses -2dB treble.
Buy the Adam Audio T8V if you want one new; the Thomann Swissonic A306 is discontinued, so only look for it used.

Adam Audio T8V: $719.98 per pair 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. 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.

Thomann Swissonic A306: $250 per pair Discontinued Thomann eBay
Pros: With the treble control set to -2dB, Erin measured a 7.29 ideal-subwoofer score and 43.9Hz -3dB bass extension. This is a useful affordable monitoring option when carefully set up, with onboard controls for basic tonal adjustment. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 89.9dB.
Cons: The published result is not the flat-control setting: it specifically uses -2dB treble. Even then, the response spans 2.8dB from 300Hz to 5kHz, so balance is not as even as the leaders. Bass output and vertical listening position remain practical limitations. Discontinued.
