Short answer: the JBL 708P for better sound quality, the Kali Audio LP-6 for the lower price. The JBL 708P ranks #20 of 40 powered bookshelf speakers at $4000. The Kali Audio LP-6 ranks #29 at $298, $3702 cheaper.
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 sound quality matters more than the price. Buy the Kali Audio LP-6 if the price matters more than sound quality.

JBL 708P: $4000 Bhphotovideo
Pros: CEA2034 spinorama shows extremely good frequency response both on- and off-axis, with excellent horizontal directivity. Bi-amplified 500W design (250W woofer, 250W compression driver) handles an 8” woofer and JBL’s 2409H compression tweeter.
Cons: A port resonance creates a mild rise around 600-900Hz. Vertical dispersion is narrower than horizontal, so staying within a few degrees of the tweeter axis matters. Distortion climbs at 96dB SPL, with the tweeter reaching about 2.5% THD at elevated levels.

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.
