The KRK S8.4 is a compact 8" powered studio subwoofer that extends the low end of any nearfield monitoring setup. The custom-voiced glass aramid composite woofer and Class D amplifier deliver tight, defined bass with fast transient response. A four-position selectable crossover matches the sub to your existing monitors, and an optional bypass footswitch lets you compare your mix with and without the subwoofer without leaving your listening position.

Crossover & Integration
