KRK S10.4-NA Overview

Audio engineers, studio musicians, and audio enthusiasts looking for a high-quality active subwoofer to extend the low frequencies of their monitor setup will be thrilled with the KRK S10.4, a fourth-generation powered studio subwoofer that delivers tight defined bass with remarkable transient performance, control, and punch. Adding this subwoofer to your 2.1 setup or 5.1 surround environment will optimize your mixing and listening experience.

The S10.4 utilizes a 160W Class-D amplifier to power the 10" glass-aramid composite woofer which offers a 30 to 110 Hz frequency response with a peak SPL of 117.2 dB. XLR, 1/4", and RCA inputs and outputs are available, allowing you total flexibility when connecting additional subs and monitors. A four-position selectable crossover lets you adjust the subwoofer settings to easily match your existing monitors. The S10.4 can be paired with any full-range studio monitor, but really shines when paired with KRK's Rokit and VXT monitors. The curved design with front-firing bass port provide placement flexibility. Other notable features include polarity and input sensitivity controls as well as a ground lift to prevent ground loops. The rugged MDF enclosure ensures maximum strength and protection.

Bypass Footswitch
  • Mix with confidence. The bypass footswitch control allows you to quickly mute the sub and send full-range audio to your recording monitors.
Heavy-Duty Enclosure
  • KRK Subwoofers feature reinforced MDF enclosures for maximum strength and durability. Never let a spilled beer or wild ninja roundhouse kick stop your mixing session again.
Front-Firing Port
  • KRK engineered the front port to provide low-frequency extension while reducing boundary coupling. The unique shape is optimized to avoid port turbulence.
Plays Well with Others
  • Dedicated crossover and optional high-pass filter bypass means that the subwoofers are the perfect complement to powered monitors. From mixing and mastering to sound design, broadcast, and production work—KRK has you covered.

KRK S10.4-NA Reviews

booming sound for powerful effects

By David

I purchased this subwoofer to go along with a Nord Grand 2 Piano that has the paired Nord speakers. Adding the bass from this subwoofer makes for a powerful instrument. Splitting the keyboard with a string bass on the bottom end makes the keyboard extremely versatile and gives a huge dynamic range for the music you can get from this keyboard. With the piano sounds it also works well to give great definition to those low range keys. Ths subwoofer is very easy to setup and understand. It provides lots of options for connections and configuration. I am very happy with it and wonder why I didn't get one sooner.

What I’ve been missing!

I have had studio monitors for almost 12 years now and I barely got this subwoofer. I realized I was not hearing those subsonic waves. With this unit you’re able to hear those low frequencies. Sounds amazing!
