Short answer: the Rythmik LV12. It ranks #8 of 212 subwoofers by sound quality, rated 4.2/5, at $899. The KRK S12.4 ranks #28, rated 3.9/5, at $649, $250 cheaper, which does not close the gap in sound quality.
The case for the KRK S12.4: A 12 inch studio subwoofer built to pair with desk monitors, with a selectable crossover and a footswitch for quick mix checks. Watch for: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
The Rythmik LV12 is the better-sounding choice. A great value 12 inch servo controlled subwoofer with deep bass and switchable tuning for depth or loudness. Watch for: At 495 by 381 by 470mm and 69 lbs (31.3 kg) it is a large, heavy cabinet for a 12 inch subwoofer.
Buy the Rythmik LV12. It is rated higher for sound quality, and saving $250 with the KRK S12.4 does not make up for the sound-quality gap.
Worth knowing: the KRK S12.4 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.7 to 4.1, so treat this verdict as provisional.
