Short answer: both are discontinued, so this only matters if you are buying used. Used, the Kali Audio LP-6 is the better pick: it ranks #32 of 68 powered bookshelf speakers by sound quality (rated 4.3/5), against #45 (rated 4.1/5) for the JBL 4329P. If you want one new, the Neumann KH 150 ranks #8 at $3,398.
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 Kali Audio LP-6 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Neumann KH 150 instead.

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.

Kali Audio LP-6: $298 per pair Discontinued eBay
Newer model: the Kali Audio LP-6 V2, ranked higher, rated 4.4/5.
Pros: The original LP-6 measures 43.9Hz at -3dB and scores 6.33 with an ideal subwoofer. Its waveguide and placement controls make it a credible budget studio monitor, with useful bass for ordinary music listening. Measured bass extension of 43.9Hz (-3dB).
Cons: The measured 2.9dB response span from 300Hz to 5kHz is less even than the newer LP-6 V2. First-generation amplifier hiss can be distracting at short distances. Do not assume the V2’s noise improvements or measurements apply to this model. A port resonance adds bumps around 900Hz to 1kHz. Discontinued.
