Short answer: the JBL 708P, if you are buying new. The Kali Audio LP-6 ranks higher than it (#32 vs #39 of 68 powered bookshelf speakers, 4.3/5 vs 4.2/5) but is discontinued, so only consider it used; the JBL 708P is still sold new at $4,000.
The case for the JBL 708P: CEA2034 spinorama shows extremely good frequency response both on- and off-axis, with excellent horizontal directivity. The tradeoff: A port resonance creates a mild rise around 600-900Hz.
What the Kali Audio LP-6 offers: CEA2034 spinorama shows generally flat on-axis response with excellent horizontal and vertical directivity. Watch for: Port resonance creates bumps around 900Hz-1kHz in the frequency response.
Buy the JBL 708P if you want one new; the Kali Audio LP-6 is discontinued, so only look for it used.

JBL 708P: $4000 per pair B&H Photo Video eBay
Pros: Erin’s measurements give 43.9Hz -3dB extension and a 6.91 ideal-subwoofer score, with useful bass from a professional active monitor. The waveguide and onboard processing make it a practical choice for a carefully installed studio system. Measured bass extension of 43.9Hz (-3dB).
Cons: The 2.6dB response span from 300Hz to 5kHz includes audible-relevance irregularities, with port-region features and vertical crossover sensitivity. High-level distortion remains a constraint. Its professional positioning and amplifier power do not make it automatically more neutral than the cheaper 308P MKII. A port resonance adds a mild rise around 600 to 900Hz, and vertical dispersion is narrower than horizontal, so stay within a few degrees of the tweeter axis.

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.
