The KRK 12sHO Active Subwoofer can easily handle the sonic rigors of the surround sound arena making it an ideal match for KRKs Expos or VXT8 monitors driven to high sound pressure levels. It gives the engineer artist and producer the opportunity to experience accurate bass reproduction down to 29Hz.
Ultra-Accurate Bass Extension The KRK12sHO brings big system performance to any studio environment where ultra-accurate bass extension and maximum sound levels are required. While subsonic frequencies are heavily implemented in some musical genres all studios will benefit from the use of a sub to monitor this low frequency content. 12-Inch Kevlar Driver The KRK 12sHO cabinet features a 12-inch high excursion woven Kevlar driver cone set in a curved baffle front plate designed to virtually eliminate diffraction distortion. A front-firing specially-designed port provides low-frequency extension while reducing boundary coupling and port turbulence. Generous Frequency Range The integrated power amplifier delivers 400w RMS performance yielding a sound pressure level of 113dB music and 116dB peak. The crossover is a fixed high-pass 80Hz with a subwoofer low-pass filter control variable from 60Hz to 160Hz giving the KRK12sHO a generous frequency range of 29 to 160Hz to complement the sonic signature of any control room. Broad Connectivity Options The cabinet features combi-jack inputs thermal and overload/clip protection LFE input gain XLR outputs a special subwoofer/line bypass footswitch connection phase reverse switch and variable phase adjust capabilities. Features Curved Baffle Curved front plate design virtually eliminates diffraction distortion Front-firing Port to provide low frequency extension while reducing boundary coupling and the unique shape is optimized to avoid port turbulence Bypass Footswitch Control to allow you to defeat the sub and provide full range audio to your recording monitors for use with a standard latching 1/4 inch mono footswitch 12″ Kevlar Driver – High Excursion woven Kevlar driver cone Thermal and Overload / Clip Protection to prevent damage Input Sensitivity on rear of unit allows a high resolution gain range with labeled positions for MUTE +6dBu and -8dBu Specifications Configuration: Front loaded vented subwoofer System type: Active Subwoofer Low-Frequency: 12″ woven Kevlar High Performance woofer Frequency Response: 29.2Hz – 60Hz – 160Hz (L/R inputs) 29.1Hz – 211Hz (LFE input) Max Peak SPL: 123 dB Amplifier Class: Class A-B Power Output: 400 Watts Continuous @ 1 THD+N @ 100Hz SNR (signal to Noise Ratio): 92dB Amplifier Distortion (THD+N): Input Impedance (Ohms): 10 kΩ Balanced or unbalanced Ground Lift: On / Off Low Pass Frequency: 60Hz to 160Hz HPF bypass: with footswitch only Footswitch: Included Phase: Rotatable Phase + Polarity Switch System Volume: -30dB to +6dB Indicators: Power protection limiter Input Connectors: Balanced XLR for Left and Right Inputs LFE input: Balanced XLR Output Connectors: Stereo Balanced XLR for left and right full range with foot switch engaged 80Hz HP without foot switch engaged.
