Short answer: the Aalto Speakers Aalto 3 Active Pro. It ranks #11 of 119 powered bookshelf speakers by sound quality (rated 4.7/5); the Kali Audio LP-6 V2 ranks #37 (rated 4.4/5).
The Aalto Speakers Aalto 3 Active Pro is the more accurate pick. 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. Its measured preference score, a predictor of how neutral it sounds, is 7.49 against 5.53 for the Kali Audio LP-6 V2. Watch for: External amplification and system setup make this less straightforward than a self-contained desktop pair.
What the Kali Audio LP-6 V2 does well: 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 tradeoff: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

Aalto Speakers Aalto 3 Active Pro: €5,490 per pair Aalto Speakers eBay
Same family: the Aalto Speakers Aalto 1 EVO (smaller bookshelf, rated 4.3/5), the Aalto Speakers Aalto 3 Passive (smaller bookshelf, rated 4.2/5) and the Aalto Speakers Aalto 9 (floorstanding, rated 4.7/5).
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: $498 per pair B&H Photo Video $249.00 eBay
Older model: the Kali Audio LP-6 (ranked lower, rated 4.3/5). See every Kali Audio LP generation.
Same family: the Kali Audio LP-8 V2 (larger bookshelf, ranked lower, rated 4.1/5) and the Kali Audio LP-UNF (larger bookshelf, rated 3.9/5).
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.
