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 Sigberg Audio Manta ranks #42, rated 4.1/5, and costs $32,220, so there is not much of a tradeoff to weigh.
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 catch: The 2.5dB response span from 300Hz to 5kHz leaves some tonal unevenness.
What the Sigberg Audio Manta does well: Designed for use with separate subwoofers, the Manta is a main speaker for a complete system rather than a conventional full-range desktop pair. Watch for: Separate subwoofers and system setup add cost and occupy more space than the main speakers alone.
Buy the Kali Audio LP-6 V2. It is rated higher for sound quality than the Sigberg Audio Manta and costs less, which makes it the one to get unless you need something the other one 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.
