Short answer: the JL Audio Fathom f212v2. It ranks #41 of 143 subwoofers by sound quality, rated 4.3/5, at $10,000; the Genelec W371A ranks #121, rated 3.9/5, and costs $10,795, so there is little reason to consider the other one.
The JL Audio Fathom f212v2 is the better-sounding option. JL Audio’s dual-driver Fathom: two 12” W7 drivers and a 3600W amplifier in a tall sealed cabinet, rated 20 to 97Hz (±1.5dB) and 15Hz at -10dB anechoic, with automatic room optimization. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured JL Audio Fathom f113 (118.9dB in the 40 to 80Hz CEA-2010 bands): two 12” drivers with twice the cone area and 3600W should add several dB, putting it among the louder sealed subs.
Why pick the Genelec W371A: A floor-standing woofer system that sits under the Genelec 8341A, Genelec 8351B or Genelec 8361A coaxial monitors to make a full-range speaker. The tradeoff: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Buy the JL Audio Fathom f212v2. It is rated higher for sound quality than the Genelec W371A and costs less, so only choose the other one for a particular feature it does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: JL Audio Fathom f212v2 3.9 to 4.5; Genelec W371A 3.7 to 4.1). Treat this verdict as provisional.

Genelec W371A: $10,795 Estimated B&H Photo Video eBay
Pros: A floor-standing woofer system that sits under the Genelec 8341A, Genelec 8351B or Genelec 8361A coaxial monitors to make a full-range speaker. Front 14-inch (356mm) and rear 12-inch (305mm) woofers, each with 400W of Class D amplification, reach down to 23Hz at -6dB with 120dB short-term output, and three selectable modes steer bass directivity to suit the room. Analog XLR and AES/EBU inputs with GLM calibration.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. It only works with Genelec’s The Ones monitors and is meant to be used in pairs, one under each speaker. Room calibration needs Genelec’s GLM kit or 9320A controller, sold separately.
