The S8.4 powered studio subwoofer builds upon KRKs legacy for sonic accuracy in a compact form factor. The custom-voiced, glass-aramid woofer delivers 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 S8.4 subwoofer with KRK or another studio monitor delivers an optimized mixing and listening experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without switching off the subwoofer. KRKs S8.4 subwoofer doesnt just deliver precise bass and a rich feature set: its the next dimension in subwoofer performance.
