KRK S8.4 Active Subwoofer with Bypass

Powered Studio Subwoofer

The S8.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy in a compact form factor. The custom-voiced, glass-aramid woofer delivers tight, defined bass, while the Class-D power amplifier dramatically increases transient response, control and punch. The four-position selectable crossover lets you adjust the subwoofer setting easily to your existing monitors.

Pairing the S8.4 subwoofer with KRK or another studio monitor delivers an optimized mixing and listening experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without switching off the subwoofer. KRK’s S8.4 subwoofer doesn’t just deliver precise bass and a rich feature set: it’s the next dimension in subwoofer performance.

S8.4 Features

  • 8" glass aramid composite woofer
  • Bass extension to 29Hz with a max SPL of 112.8 dB
  • Footswitch control enables/disables sub and crossover filter (footswitch not included)
  • Redesigned cabinet with a lower profile and front-firing bass port
  • Powerful, lightweight Class D amplification
  • Optimized four-position crossover control
  • Universal connectivity: XLR, 1/4" TRS, and RCA inputs and outputs
  • Polarity and input sensitivity controls
  • Ground lift switch prevents ground loops

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

We 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 our subwoofers are the perfect compliment to powered monitors. From mixing and mastering to sound design, broadcast and production work - KRK has you covered.
