KRK S8.4

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.
