KRK - S8.4
8" Powered Studio Subwoofer
Add some 'umph' to your set upThe KRK S8.4 powered studio subwoofer is a continuation on KRK’s legacy for audio accuracy in a compact form factor. The custom-voiced, glass-aramid woofer provides tight, defined bass, while the Class-D power amplifier drastically enhances transient response, control and punch. The four-position selectable crossover allows you to adjust the subwoofer setting easily to your existing monitors.
Pairing the S8.4 subwoofer with KRK or another studio monitor results in an optimized mixing and listening experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without turning off the subwoofer.

Heavy Duty EnclosureKRK 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 PortWe engineered the front port to provide low frequency extension while reducing boundary coupling. The unique shape is optimized to avoid port turbulence.
