Short answer: the Kali Audio LP-6 V2. It ranks #25 of 68 powered bookshelf speakers by sound quality, rated 4.4/5, at $398; the JBL 708P ranks #39, rated 4.2/5, and costs $4,000, which makes this an easy call rather than a real tradeoff.
On the Kali Audio LP-6 V2 side: Outstandingly neutral active monitor for the money, with no audible amplifier hiss in Erin’s listening and excellent horizontal directivity from the contoured waveguide. Set against that: A vertical directivity disturbance around 1.5-2kHz makes ear height important; desk or console reflections and ceiling bounce can expose the crossover lobing, so absorption may help.
What the JBL 708P gets right: CEA2034 spinorama shows extremely good frequency response both on- and off-axis, with excellent horizontal directivity. The catch: A port resonance creates a mild rise around 600-900Hz.
Buy the Kali Audio LP-6 V2. It is rated higher for sound quality than the JBL 708P and costs less, so only choose the other one for a particular feature it does better.

Kali Audio LP-6 V2: $398 per pair Amazon B&H Photo Video eBay
Older model: the Kali Audio LP-6 (ranked lower, rated 4.3/5).
Pros: Erin’s measurements give a 7.48 ideal-subwoofer score and 42.5Hz -3dB bass extension, a strong combination for an affordable nearfield monitor. The waveguide and placement switches help with practical setup, and the second generation improves close-range noise behavior. Measured bass extension of 42Hz (-3dB).
Cons: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness. Vertical crossover behavior makes ear-height placement important, and compression limits loud bass playback. Its good tonal score is not evidence of the output capability of a much larger monitor.

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.
