Short answer: the JBL 306P MKII, if you are buying new. The Kali Audio LP-6 ranks higher than it (#32 vs #41 of 68 powered bookshelf speakers, 4.3/5 vs 4.1/5) but is discontinued, so only consider it used; the JBL 306P MKII is still sold new at $398.
What the Kali Audio LP-6 gets right: CEA2034 spinorama shows generally flat on-axis response with excellent horizontal and vertical directivity. The catch: Port resonance creates bumps around 900Hz-1kHz in the frequency response.
On the JBL 306P MKII side: CEA2034 spinorama shows a nice, smooth on-axis response with very good directivity control for a compact 6.5” monitor. Set against that: A narrow but noticeable dip around 1.6kHz shows up in the on-axis and listening-window curves.
Buy the JBL 306P MKII, since the Kali Audio LP-6 is discontinued and only worth hunting down used.

The Two Speakers In Full
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.

JBL 306P MKII: $398 per pair B&H Photo Video eBay
Pros: A 6.94 ideal-subwoofer score and 46.9Hz measured -3dB extension make this a useful affordable nearfield monitor. The waveguide supports broad horizontal listening coverage, and basic boundary controls help with setup. Measured bass extension of 46.9Hz (-3dB).
Cons: The 3.4dB response span from 300Hz to 5kHz is less even than the 308P MKII’s, with midrange resonances affecting neutrality. Hiss can matter at a quiet desk, while bass distortion limits demanding playback. A subwoofer improves bandwidth but does not remove the midrange irregularities. A narrow dip around 1.6kHz shows in the on-axis and listening-window curves.
