Fluid Audio is a pro audio manufacturer based in Carlsbad, California, founded in 2011 by loudspeaker engineer Kevin Zuccaro, a JBL and Cerwin-Vega veteran who previously led the studio monitor program at M-Audio. The company designs powered reference monitors and related studio gear aimed at home recordists, producers, and engineers, with a focus on delivering accurate translation at accessible price points.

The brand is closely associated with coaxial, point-source designs in its FX line (the FX8 and DSP-controlled FX50v2 and FX80v2), which mount the tweeter at the center of the woofer for a single acoustic origin and improved off-axis response. Alongside the coaxial FX series, Fluid Audio makes the compact F-series nearfields (F4, F5, F8), the C-series desktop monitors with Bluetooth input (C5BT, C50BT), and the three-way Image 2 reference monitor. A separate Fluid Professional line extends the catalog with DSP-controlled monitoring for higher-end rooms and immersive audio setups.

Fluid Audio has 11 products cataloged on Equipboard, including Active & Passive Monitors, Studio Subwoofers, and Monitors & Accessories. Their gear is featured by 2 artists, with the strongest followings in Pop, Rock, and Folk, World, & Country. Notable users include Austin Hull and A.R. Rahman.
