The KRK S12.4 is a 12" powered studio subwoofer with a 220W Class-D amp, designed to extend your nearfield monitor system down to club-level low end while staying tight and controlled. With a front-ported, low-profile cabinet and flexible I/O, it’s ideal for modern music production, post, and EDM-ready project studios.
Key Highlights
12" Kevlar® composite woofer for accurate, punchy low frequencies tailored to studio monitoring.
220W Class-D power delivers up to ≈120 dB max SPL, giving plenty of headroom for larger control rooms.
Deep bass extension – frequency response 26 Hz–97 Hz (±3 dB) with usable range down to about 23 Hz, revealing sub-bass you can’t hear on typical nearfields.
Front-firing slot port & low-profile cabinet minimize boundary issues and make placement near walls or under a desk easier.
Flexible connectivity – XLR, 1/4" TRS, and stereo RCA inputs/outputs to integrate with almost any monitor setup or additional subs.
The S12.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy and stellar performance. The custom-made, Kevlar® woofer delivers ultra-tight, defined bass, while the Class-D power amplifier dramatically increases transient response, control, and punch. The four-position selectable crossover lets you adjust the subwoofer setting easily to your existing monitors.
Pairing the S12.4 with KRK or another studio monitor delivers an optimized listening and mixing experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without switching off the subwoofer. The powerful S12.4 subwoofer doesn’t just deliver precise, ultra-low bass and a rich feature set: it’s the next dimension in subwoofer performance.
