Short answer: the Klipsch The Nines on measured sound quality, the Adam Audio T8V on price. The Klipsch The Nines ranks #39 of 67 powered bookshelf speakers at $999.99. The Adam Audio T8V ranks #53 at $349.99, $650 cheaper.
The case for the Adam Audio T8V: Quite balanced and neutral, very close to the Yamaha HS8. The tradeoff: A crossover-region notch around 4.6kHz where tweeter and woofer interact, and a hole in the vertical response below the tweeter axis - keep the tweeter at or above ear height.
On the Klipsch The Nines side: Erin calls these his favorite Klipsch speaker he has heard. Set against that: The app’s flat setting leaves the treble elevated, and Erin preferred a -2dB tweeter trim.
Buy the Adam Audio T8V if the price is the priority over sound quality, or the Klipsch The Nines if sound quality is the priority over the price.
The Adam Audio T8V is not a sound-quality pick. It sits near the bottom of the 67 powered bookshelf speakers; there are better options higher up.

The Two Speakers In Full
Adam Audio T8V: $699.98 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 45Hz (-3dB).
Cons: The 5.42 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.

Klipsch The Nines: $999.99 per pair Crutchfield eBay
Pros: The 1.7dB response span from 300Hz to 5kHz supports even mids, and measured -3dB extension is 42.5Hz. Extensive consumer connections and app adjustment make it convenient for TV and music, while the horn provides a focused listening presentation. Measured bass extension of 41Hz (-3dB), with a measured sensitivity of 82.5dB.
Cons: The 5.99 ideal-subwoofer score reflects limitations beyond the narrow midband span. Horizontal coverage is relatively focused, so placement matters for multiple seats. The reviewer preferred reduced treble, and bass limiting at higher playback levels means the large woofer is not a guarantee of unlimited output.
