Short answer: the JBL 4305P for better sound quality, the Klipsch The Nines for the lower price. The JBL 4305P ranks #28 of 66 powered bookshelf speakers at $2200. The Klipsch The Nines ranks #39 at $999.99, $1200.01 cheaper.
What the JBL 4305P offers: Erin measured a 45Hz F3 and heard solid 40–50Hz in-room extension—excellent for a compact 5.25-inch active monitor. Watch for: The limiter becomes conspicuous around 96dB: Erin measured about 8dB lost near 50Hz at the highest drive and achieved roughly 93dB unweighted at 2m in-room, so this is a near/midfield system rather than a high-output theater…
What the Klipsch The Nines offers: Erin calls these his favorite Klipsch speaker he has heard. Watch for: The app’s flat setting leaves the treble elevated, and Erin preferred a -2dB tweeter trim.
Buy the JBL 4305P if sound quality is the priority over the price, or the Klipsch The Nines if the price is the priority over sound quality.

The Two Speakers In Full
JBL 4305P: $2,200/pair Amazon JBL eBay
Pros: The measured 1.5dB response span from 300Hz to 5kHz supports even mids, with a 6.54 ideal-subwoofer score and 45.4Hz -3dB bass extension. Integrated consumer connectivity makes this a more convenient living-room system than many studio monitors.
Cons: Crossover-region directivity changes mean the narrow on-axis span does not describe every listening angle. Limiting becomes relevant at high output, particularly with bass-heavy music. It suits near- to midfield listening better than the largest high-output systems here.

Klipsch The Nines: $999.99 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.
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.
