The KRK S12.4 is not ranked yet. We rank speakers on independent measurements, and none have been published for it so far. It is likely to perform similarly to the model it replaces, though we can’t confirm that until it has been measured. See all Subwoofers rankings for measured picks.

KRK S12.4: $839.00 Amazon eBay
Replaces: the KRK Systems 12S (ranked #25 of 145 in its size class).
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.
