Short answer: the Klipsch The Nines II if sound quality matters most, the Klipsch The Nines if price matters most. The Klipsch The Nines II ranks #41 of 79 powered bookshelf speakers, rated 4.3/5, at $2,399.99. The Klipsch The Nines ranks #46, rated 4.2/5, at $999.99, $1,400 cheaper.
The case for the Klipsch The Nines II: Flagship active monitor combining Onkyo-designed amplification delivering 260W continuous power (520W peak) with an 8-inch Jet Cerametallic woofer and 1-inch titanium LTS vented tweeter on a 90x90 Tractrix horn. The catch: Large, heavy cabinet (over 57.3 lbs (26 kg) for the system) demands substantial shelf or heavy-duty stand placement.
What the Klipsch The Nines does well: The 1.7dB response span from 300Hz to 5kHz supports even mids, and measured -3dB extension is 42.5Hz. The catch: The 6.90 ideal-subwoofer score reflects limitations beyond the narrow midband span.
Buy the Klipsch The Nines II when sound quality outweighs the price for you, and the Klipsch The Nines when the price outweighs sound quality instead.

Klipsch The Nines: $999.99 per pair Crutchfield eBay
Newer model: the Klipsch The Nines II, ranked higher, estimated 4.3/5.
Smaller models: the Klipsch The Sevens (ranked lower, rated 3.7/5) and the Klipsch The Fives (rated 4.3/5).
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. Erin called it his favorite Klipsch speaker. Measured bass extension of 42.5Hz (-3dB), with a measured sensitivity of 82.5dB.
Cons: The 6.90 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. The app’s flat setting leaves treble elevated; Erin preferred a -2dB tweeter trim.
