KRK Subwoofers S12.4 12" Active Studio Sub

Pro’s choice for mixing & mastering

Audio engineers, studio musicians, and audio enthusiasts looking for a high-quality active subwoofer to extend the low frequencies of their monitor setup will be satisfied with the KRK S12.4, a Fourth-Gen' powered studio subwoofer that delivers tight defined bass with remarkable transient performance, control, and punch. Adding this subwoofer to your 2.1 setup or 5.1 surround environment will optimize your mixing and listening experience.

Brilliant Low-end
After KRK’s legacy for sonic accuracy and stellar performance. The S12.4 utilizes a 220W Class-D amplifier to power the 12" glass-aramid composite woofer which offers a 32 to 139 Hz frequency response with a peak SPL of 119.9 dB. XLR, 1/4", and RCA inputs and outputs are available, allowing you total flexibility when connecting additional subs and monitors.

Bypass Footswitch
Mix with confidence. The bypass footswitch control allows you to quickly mute the sub and send full-range audio to your recording monitors.

Heavy Duty Enclosure
KRK Subwoofers feature reinforced MDF enclosures for maximum strength and durability. Never let a spilled beer or wild ninja roundhouse kick stop your mixing session again.

Front-firing Port
We engineered the front port to provide low frequency extension while reducing boundary coupling. The unique shape is optimized to avoid port turbulence.

Plays well with others
Dedicated crossover and optional High-pass filter bypass means that the S12.4 can be paired with any full-range studio monitor, but really shines when paired with KRK's Rokit and VXT monitors. 

Additional features include polarity and input sensitivity controls as well as a ground lift to prevent ground loops. The rugged MDF enclosure and all-steel grille ensure maximum strength and protection. From mixing and mastering to sound design, broadcast and production work - KRK has you covered.
