KRK 12sHO Active Subwoofer

Full Description

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.
