KRK S12.4 – 12 Inch Active Studio Subwoofer

Powered Studio Subwoofer
The S12.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy and stellar performance. The custom-made, Kevlar woofer delivers ultra-tight, defined bass, while the Class-D power amplifier dramatically increases transient response, control, and punch. The four-position selectable crossover lets you adjust the subwoofer setting easily to your existing monitors.

Pairing the S12.4 with KRK or another studio monitor delivers an optimized listening and mixing experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without switching off the subwoofer. The powerful S12.4 subwoofer doesn’t just deliver precise, ultra-low bass and a rich feature set: it’s the next dimension in subwoofer performance.

KRK Subwoofers
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 our subwoofers are the perfect compliment to powered monitors. From mixing and mastering to sound design, broadcast and production work – KRK has you covered.
