Short answer: the JBL 4329P for better sound quality, the Kali Audio LP-6 for the lower price. The JBL 4329P ranks #19 of 40 powered bookshelf speakers at $4500. The Kali Audio LP-6 ranks #29 at $298, $4202 cheaper.
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.
On the Kali Audio LP-6 side: CEA2034 spinorama shows generally flat on-axis response with excellent horizontal and vertical directivity. Set against that: Port resonance creates bumps around 900Hz-1kHz in the frequency response.
Buy the JBL 4329P if sound quality matters more than the price. Buy the Kali Audio LP-6 if the price matters more than sound quality.

The Two Speakers In Full
JBL 4329P: $4,500 Amazon
Pros: 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, with strong bass authority rather than a rolled-off, thin low end. Wide, constant horizontal directivity through the midrange and into the treble (about ±60°, wider than most horn-loaded designs which tend to run closer to ±40°) gives a wide, stable stereo image without needing to toe the speakers out and lose top-end energy. The reviewer listened for an hour-long sessions repeatedly without listener fatigue, across two very different rooms, with consistently great results in both. Extensive connectivity: USB, Optical, Bluetooth, analog, 3.5mm, AirPlay 2, and 24-bit/192kHz support; comes with a remote.
Cons: No HDMI input, a real drawback if you want to run these directly off a TV’s ARC. The supplied ethernet link cable between the two speakers is short - workable at close range but not long enough for wider speaker placement, so budget for a longer aftermarket cable if your setup needs it. A dip around 900Hz shows up in the on-axis measurement that the reviewer couldn’t fully explain (ruled out the ports as the cause, suspects cabinet edge diffraction), though it wasn’t something that bothered him in listening. At $4,500/pair, this is a serious investment for a bookshelf-format speaker.

Kali Audio LP-6: $298 Discontinued Bhphotovideo
Pros: CEA2034 spinorama shows generally flat on-axis response with excellent horizontal and vertical directivity. Deep bass distortion stays below the fundamental tone throughout testing, and the noise floor is low enough that hiss isn’t audible at normal listening distance. Exceptional value at $298 per pair.
Cons: Port resonance creates bumps around 900Hz-1kHz in the frequency response. Distortion measurements are worse than the on-axis response alone would suggest. Diffraction causes a treble rise above 10kHz, and bass shelves down slightly in the low end. Discontinued.
