Short answer: the JBL 4329P for bass depth, the Klipsch The Nines for the more enthusiastic review. The 4329P runs anechoic to 30Hz (measured F3 31Hz) with low-20s reach in-room but has no HDMI. Erin calls The Nines his favorite Klipsch he has heard, though its flat app setting leaves treble elevated and he preferred a -2dB tweeter trim.
What the JBL 4329P offers: Genuinely full-range performance for a bookshelf-style speaker - anechoic response extends to 30Hz (measured F3 31Hz), reaching into the low 20s Hz range in-room depending on placement. Watch for: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC.
Buy the Klipsch The Nines. It is rated higher for sound quality and still sold new, while the JBL 4329P is discontinued.

The Two Speakers In Full
JBL 4329P: $4,500 per pair Discontinued eBay
Pros: Measured -3dB extension of 32.2Hz provides deeper native bass than the smaller 4305P. Integrated amplification and streaming make it convenient for a full-range living-room system, and its larger format is useful when scale matters. Measured bass extension of 31Hz (-3dB), with a measured sensitivity of 102.2dB.
Cons: The measured 4.5dB response span from 300Hz to 5kHz includes a notable midrange dip, so it is not as neutral as its size and price might suggest. Its 6.72 ideal-subwoofer score trails the 4305P. There is no HDMI connection for the simplest TV hookup. Discontinued.

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.
