KRK S12.4
KRK S12.4
The KRK S12.4 is an active studio subwoofer. A specially designed Kevlar woofer delivers exceptionally tight and precisely defined bass, while the Class-D amplifier significantly improves transient response, control, and punch. A 4-position switchable crossover makes it easy to match the subwoofer settings to your existing monitors. Pairing the S12.4 with KRK monitors or other studio monitors provides an optimised listening experience with extended low-end, while the footswitch-enabled bypass control allows you to quickly mute the subwoofer and send full-range audio to your studio monitors.
