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. 12" Woven Kevlar® High Performance Woofer Bass Extension to 29Hz with a Max SPL of 123 dB Quad-vented, Front-firing Bass Port 400W Class A-B Power 92 dB Signal to Noise Ratio Combo XLR-1/4"" TRS Inputs with XLR Outputs Dedicated LFE Channel with Combo XLR-1/4" TRS Input Sweepable Crossover Control Bypass Foot Control included Reinforced MDF Enclosure Specifications Configuration: Front Loaded, Vented Subwoofer System Type: Active Subwoofer Low-Frequency Transducer: 12" Woven Kevlar® High Performance Woofer Frequency Response: 29.2Hz - 160Hz (L/R inputs), 29.1Hz - 211Hz (LFE input) Max Peak SPL: 123 dB Amplifier: Class A/B Power Output (Continous): 400 Watts @ 1% THD+N @ 100Hz Signal to Noise Ratio: 92 dB Amplifier Distortion (THD + N): ≤ 0.1% @-3dB Of Max Power Output 20Hz-200Hz Input Impedance: 10 KΩ Balanced or Unbalanced Ground Lift: On/Off HPF Bypass: With Footswitch Only Footswitch: Included Indicators: Power, Protection, Limiter Input Connectors: Balanced XLR for Left & Right inputs LFE Input: Balanced XLR Output Connectors: Balanced XLR for Left & Right AC Power Input: Selectable 110V-120V / 220V0240V Enclosure: 18mm & 36mm Reinforced MDF Finish: Textured Paint Hardware: N/A Dimensions (H x W x D): 20" (508 mm) X 20" (508 mm) X 22.48" (571mm) Weight: 109.7 lb.
