Short answer: the WiiM Sub Pro. It ranks #116 of 212 subwoofers by sound quality, rated 3.6/5, at $479; the KEF KC62 ranks #212, rated 2.5/5, and costs $1,699.99, so there is not much of a tradeoff to weigh.
The WiiM Sub Pro is the better-sounding option. Independent CEA-2010 testing records 77.4 dB at 20 Hz and 111.8 dB through 40-80 Hz. Watch for: The 398.8H x 299.7W x 322.6D mm cabinet and 35.3 lbs (16.0 kg) mass still need deliberate placement.
The case for the KEF KC62: Dual 6.5-inch force-canceling drivers with 1000W in ultra-compact basketball-sized sealed enclosure.
Buy the WiiM Sub Pro. It is rated higher for sound quality than the KEF KC62 and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
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.
