Fluid Audio F8S

8″ powered reference subwoofer


200 W RMS, Class D, standby circuit, XLR in/out, TRS, RCA, bypass pedal, fader volume

Designed for recording studios, gaming, home theaters and more, the Fluid Audio F8S active subwoofer delivers exceptional bass response in a compact footprint.

Many types of music benefit from bass extension – from Hip-Hop, to House, to Rock. Being able to hear your mix with this bass extension is critical to accurately creating your music. The F8S subwoofer allows you to hear every detail down to 30Hz – and in a compact size.

Mix Engineers want the confidence to know that their mixes translate well on all types of systems. That is why we included a standby footswitch. With a click of the included foot pedal, you can turn the bass on or off, and audition your mix with bass extension and without.

The F8S also has two built-in EQ settings that allow for two different settings – depending on your music: A more conventional Flat response, as well as a “Punch” setting that is perfect for Dance or other mid-bass heavy music.

For further flexibility, the F8S has a variable phase adjustment to fine tune the phase for optimal matching to your L/R monitors (0-180 degrees), a variable low pass crossover filter control (50-200Hz) and a 80Hz high pass filter (used with foot switch) for satellite connections.
