Short answer: the Klipsch The Nines. It ranks #40 of 68 powered bookshelf speakers by sound quality, rated 4.2/5, at $999.99; the Klipsch The Sevens ranks #65, rated 3.7/5, at $999.99. The price gap is small enough that the sound-quality ranking should decide it.
Why pick the Klipsch The Nines: The 1.7dB response span from 300Hz to 5kHz supports even mids, and measured -3dB extension is 42.5Hz. The tradeoff: The 6.90 ideal-subwoofer score reflects limitations beyond the narrow midband span.
What the Klipsch The Sevens does well: Erin reported 49Hz -3dB extension, with useful bass for ordinary music listening. The tradeoff: The review found a recessed 2-4kHz region and upper-treble emphasis, producing a scooped balance that a simple treble reduction did not fully fix.
Buy the Klipsch The Nines. It is rated higher for sound quality than the Klipsch The Sevens at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
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. 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.

Klipsch The Sevens: $999.99 per pair Amazon eBay
Pros: Erin reported 49Hz -3dB extension, with useful bass for ordinary music listening. HDMI, phono, USB, optical and Bluetooth connections make the system convenient for TV and music, while app controls and a subwoofer output provide adjustment options. Bass reaches about 36Hz at -10dB, delivering a controlled thump near 40Hz in-room without strain. Measured bass extension of 49Hz (-3dB).
Cons: The review found a recessed 2-4kHz region and upper-treble emphasis, producing a scooped balance that a simple treble reduction did not fully fix. Relatively narrow horizontal coverage limits consistency across seats.
