IK Multimedia iLoud Sub

Perfect studio sound - built from the ground up.

iLoud Sub reshapes expectations of a studio subwoofer, offering deep, precise and tightly controlled low-end performance in one of the most compact formats available, while also greatly improving the sound of connected satellite speakers.

iLoud Sub is the only subwoofer that automatically calibrates both itself and any attached monitors to the room, whatever the brand, ensuring balanced, accurate and consistent sound across the full audio range, from the lowest frequencies to the highest.

Driven by ARC X’s advanced DSP, iLoud Sub gives modern music producers complete confidence in their mixing choices and allows hi-fi listeners to experience music exactly as intended.

Check out the iLoud Sub in action below:

• Smallest footprint on the market: Fits in any studio - no rearranging required

iLoud Sub is engineered to provide full-range clarity and depth while maintaining perfect balance within your space.

Occupying only a fraction of the size of traditional studio subwoofers, it integrates naturally into any workspace, delivering powerful low-end extension down to 25 Hz with tight, accurate, and musical response you can rely on in every mix.

iLoud Sub features ARC’s advanced algorithm that seamlessly analyses your acoustic environment and perfectly calibrates your monitors. Regardless of the make and model of the left and right speakers, ARC X software ensures they sound flat, balanced and free of any acoustic interference, so your mixes translate flawlessly, from bottom to top.

Modern music requires absolute precision in the low end. iLoud Sub premieres ARC X’s newest feature: automatic subwoofer setup.
