iLoud Sub delivers deep, accurate bass down to 25 Hz in the smallest footprint of any pro studio subwoofer, making it perfect for compact workspaces. Powered by ARC X, it automatically calibrates itself and any connected monitors—regardless of brand—for a balanced, reliable sound that translates everywhere. ARC X precisely aligns timing and frequency response so kicks, bass, and sound-design elements become clearer and more controlled. With a premium 6.5" driver, dual passive radiators, and 200 W power, iLoud Sub adds depth without muddying the mids. XLR/RCA I/O, USB audio, Bluetooth, and full ARC X integration make it ideal for iLoud monitors or any 3–7" nearfields. Designed to elevate small studios, it delivers clarity, confidence, and full-range accuracy in any setup.
