KRK 12SHO High Output Powered Studio Subwoofer
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.
