Short answer: a tie on sound quality. Both are rated 3.6/5 (#146 and #116 of 212 subwoofers) at nearly the same price ($479 vs $479), so choose on features and fit.
Why pick the KRK S10.4: The 10” studio subwoofer in KRK’s fourth generation, with a glass aramid woofer, a 160W Class D amplifier and a four-position crossover. Watch for: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from KRK’s measured 12S (117.1dB in the 40 to 80Hz CEA-2010 bands), which it is not expected to match.
The case for the WiiM Sub Pro: Independent CEA-2010 testing records 77.4 dB at 20 Hz and 111.8 dB through 40-80 Hz. The tradeoff: The 398.8H x 299.7W x 322.6D mm cabinet and 35.3 lbs (16.0 kg) mass still need deliberate placement.
Buy the KRK S10.4 or the WiiM Sub Pro on features: they are rated the same for sound quality at close to the same price.
About the ratings: the KRK S10.4’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.2 to 3.8, so this verdict could change once it is measured.

WiiM Sub Pro: $479.00 Amazon eBay
Pros: Independent CEA-2010 testing records 77.4 dB at 20 Hz and 111.8 dB through 40-80 Hz. The ported enclosure with an 8” driver suits a small-to-mid room.
Cons: The 398.8H x 299.7W x 322.6D mm cabinet and 16.0 kg mass still need deliberate placement. Newly launched, so long-term reliability is unproven.
