Pros: The manufacturer dataset reports a remarkably even 0.7dB response span from 300Hz to 5kHz, 34.6Hz -3dB extension and an 8.90 ideal-subwoofer preference score. If representative of the delivered system, this promises exceptionally neutral balance with useful bass reach.
Cons: External amplification and system setup make this less straightforward than a self-contained desktop pair.

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.
