Short answer: the Paradigm XR11. It ranks #22 of 212 subwoofers by sound quality, rated 4.1/5, at $3,999.99; the Sigberg Audio 10D ranks #36, rated 3.9/5, and costs $4,067.37, so there is little reason to consider the other one.
What the Paradigm XR11 does well: 11-inch ultra-high-excursion CARBON-X driver with ART surround in an ultra-rigid sealed cabinet, driven by an immense 1,100W RMS / 2,200W peak Class D amplifier. Watch for: High investment cost.
What the Sigberg Audio 10D does well: Dual 10-inch sealed with 500W RMS, 116.8dB average.
Buy the Paradigm XR11. It is rated higher for sound quality than the Sigberg Audio 10D and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Worth knowing: the Paradigm XR11 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.9 to 4.3, so treat this verdict as provisional.

The Two Speakers In Full
Paradigm XR11: $3,999.99 Estimated Paradigm eBay
Same family: the Paradigm XR13 (larger subwoofer, estimated 4.3/5).
Pros: 11-inch ultra-high-excursion CARBON-X driver with ART surround in an ultra-rigid sealed cabinet, driven by an immense 1,100W RMS / 2,200W peak Class D amplifier. Advanced Anthem Room Correction (ARC Genesis) delivers clean reference bass down to 20Hz.
Cons: High investment cost. Sealed alignment trades ultimate 16Hz output headroom compared to larger 13-inch and 15-inch flagship subwoofers.
