Short answer: the Rythmik L12. It ranks #25 of 212 subwoofers by sound quality, rated 4.0/5, at $791; the KRK S12.4 ranks #28, rated 3.9/5, and costs $839, which makes this an easy call rather than a real tradeoff.
Why pick the Rythmik L12: Rythmik’s least expensive subwoofer: a sealed 12” with Rythmik’s Direct Servo feedback, which lowers distortion and compression, and a 300W Hypex amplifier with one band of parametric EQ. The tradeoff: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured sealed Rythmik F12 (119.3dB in the 40 to 80Hz CEA-2010 bands) and placed below it, since the L12 has a less powerful amplifier.
Why pick the KRK S12.4: A 12-inch Kevlar woofer in a reinforced MDF cabinet with a front-firing port, driven by a 220W Class-D amplifier. The catch: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
Buy the Rythmik L12. It is rated higher for sound quality than the KRK S12.4 and costs less, which makes it the one to get unless you need something the other one does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Rythmik L12 3.7 to 4.1; KRK S12.4 3.7 to 4.1). Treat this verdict as provisional.

KRK S12.4: $839.00 Estimated Amazon eBay
Older model: the KRK Systems 12S (ranked lower, rated 3.9/5). See every KRK S Subwoofers generation.
Same family: the KRK S8.4 (smaller subwoofer, estimated 3.3/5) and the KRK S10.4 (smaller subwoofer, ranked lower, estimated 3.6/5).
Pros: A 12-inch Kevlar woofer in a reinforced MDF cabinet with a front-firing port, driven by a 220W Class-D amplifier. A four-position selectable crossover matches it to existing studio monitors, and the included bypass footswitch mutes the sub and sends full-range audio to the monitors for mix checks.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. It is built as a studio monitor partner, so its controls suit a desk setup more than a home theater receiver.
