KRK speakers are widely known around the world for the phenominal clarity and sound, and would you believe it, KRK have done it again with another fantastically built, powerful precision sub-woofer. If you require ultra-accurate bass extension and maximum sound level then the KRK12sHO is a great no-compromise solution for your studio. A versatile sub that can be used in any space that allows you to enable accurate mixing of lower frequencies.

The 12” woven Kevlar high performance woofer is powered by a 400-watt Class A-B amplifier so there's plenty of power on tap. The KRK12sHO has full and extensive bass management complete with full phase adjust and reverse, LFE input capability, internal and deflatable limiter and both balanced and unbalanced inputs. Further to this, a foot pedal can be plugged in to remotely bypass the sub.

Whether you are mixing a high energy track with heavily implemented subsonic frequencies or attempting to pick out unwanted low frequency components such as microphone rumble or exterior noise the KRK12sHO delivers. In a surround sound configuration sub-woofers have to replicate the bass for 5 or more channels as well as the demanding bass for the LFE channel, this is a challenge that the KRK12sHO can handle with ease.
