The KRK 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 ensured 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.
