Overview

The KRK S8.4 Powered Subwoofer delivers tight, accurate and defined bass, while a highly efficient Class D power amplifier dramatically increases transient response, control and punch. A wealth of connectivity options allows you to hook up to practically anything without the hassle of an adapter, while a four-position crossover frequency selection switch makes it easy to adjust the subwoofer setting to optimally match your existing monitors. Refinements in this generation of KRK subwoofers include modestly improved low frequency extension, improved porting for much better low frequency phase response and less port noise, a more durable inverted dust cap, optional removable grilles, redesigned cabinets with lower height profiles and less depth than their predecessors for improved placement flexibility and a timeless design with a more professional aesthetic. 

Pairing a KRK subwoofer with KRK or other studio monitors delivers an optimized listening and mixing experience with extended low end, while the exclusive bypass control feature provides full-range audio to your monitors at the click of an (optional) footswitch without having to move out of the monitoring sweet spot to turn off the subwoofer. This allows for instant comparisons with and without the subwoofer’s contributions to the sound.
