The KRK 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 optimised 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.
