Fluid Audio FC10S Studio subwoofer

Fluid Audio FC10S — 10" Powered Studio Subwoofer for Accurate Bass Extension

Engineered to deliver bass extension down to 20 Hz for mid-to-large rooms, this active 10-inch studio subwoofer pairs a 200 W Class-D amplifier with a single 10" composite paper cone. The result is the low-frequency foundation that nearfield monitors alone cannot reproduce. The FC10S is the right choice for recording and mixing engineers, producers, and gamers who need to hear — and feel — the full bottom end of their audio.

Bypass Footswitch, Angled Port, and Switchable Voicing

This model ships with a hardware bypass footswitch that mutes the sub on demand, so engineers can A/B a mix with and without bass extension in real time. A front-baffle bass-reflex port with an angled slot design combines direct-radiating output with floor loading for stronger low-end reach. A switchable Flat/Punchy voicing mode adds an 80 Hz, 5 dB boost for dance and bass-heavy material.

10" Composite Paper Woofer and Class-D Power

The driver and amplifier pairing defines how cleanly this sub reproduces low frequencies at monitoring levels.

• LF Driver: 10" composite paper cone with high-temperature voice coil and damped rubber surround
• Amplifier Power: 200 W Class-D with switching power supply for efficient, cool-running operation
• Max SPL: 100 dBA at one meter — adequate headroom for project and mid-sized rooms

Variable Crossover, Phase, and High-Pass Filter

Integration with main monitors depends on flexible crossover and phase controls.

• Frequency Range: 20 Hz – 200 Hz
• Variable Low-Pass Filter: 50 Hz – 200 Hz
• Variable Phase: 0°–180° (12-position switch)
• 80 Hz High-Pass Filter on satellite outputs, engaged via footswitch

Balanced I/O, Ground Lift, and MDF Cabinet

Wiring flexibility and solid enclosure construction matter when a sub sits under a desk or in a corner.

• Inputs: 2x XLR balanced, 2x 1/4" TRS balanced/unbalanced, 1x stereo RCA unbalanced
• Outputs: 2x XLR balanced, 2x 1/4" TRS balanced/unbalanced for full-range monitors
• Ground Lift Switch eliminates hum caused by problematic AC wiring
• Cabinet: Vinyl-laminated MDF with protective metal grille — 387 x 317 x 394 mm, 10.2 kg
