KRK S12.4 Powered 12″ Studio Subwoofer
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 thrilled with the KRK S12.4, a fourth-generation 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.
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. A four-position selectable crossover lets you adjust the subwoofer settings to easily match your existing monitors. The S12.4 can be paired with any full-range studio monitor, but really shines when paired with KRK’s Rokit and VXT monitors. The curved design with front-firing bass port provides placement flexibility. Other notable 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.
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
- KRK 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 subwoofers are the perfect complement to powered monitors. From mixing and mastering to sound design, broadcast, and production work—KRK has you covered.
