Large and powerful nearfield studio monitors require a subwoofer that can achieve high sound pressure levels—and KRK’s 12sHO is a powerful, sonically pure addition to any studio setup. Whether for stereo or surround formats, the 12sHO subwoofer reproduces low-frequency detail as well as the LFE channel’s demanding bass content. These challenging applications place demands far exceeding the capabilities of traditional low frequency drivers and power amplifiers, so KRK developed the 12sHO (HO for “High Output”) as the industry solution for all types of demanding mix situations.

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.
