iLoud Sub $599.99

Accurate low end changes everything.

Without accurate bass monitoring, low-frequency decisions are guesswork — and guesswork doesn't translate. iLoud Sub extends the low-frequency range of any monitoring system with tight, calibrated bass reproduction built for desktop and nearfield environments. Any monitoring system. Any monitor brand.

Overview

The missing piece of your monitoring system.

Accurate bass. Not just more of It.

iLoud Sub delivers tight, musical low-frequency reproduction that integrates seamlessly with your existing monitors — extending your range without the bloat or overhang that compromises translation. What you gain is clarity across the full spectrum, not just volume at the bottom.

Works with any monitor. Any brand.

iLoud Sub is not an iLoud-only accessory. Flexible analog and digital connection options provide integration with any monitoring system — so whatever monitors you use, iLoud Sub is built to complete them.

Calibrated from the bottom up

iLoud Sub includes ARC X — a calibration system designed specifically for subwoofer integration. It measures your room's low-frequency response, optimizes output for your listening position, and aligns the sub precisely with your monitors. One calibrated system. Full-range accuracy.

From stereo to full-range in one step

A stereo pair tells most of the story. iLoud Sub tells the rest — extending low-frequency awareness and giving you the confidence to make bass decisions that hold up everywhere your work is heard.

Hear the bottom of your mix

Most nearfield monitors roll off before the lowest frequencies become audible. That missing information shows up as translation problems. iLoud Sub fills that gap with accurate, calibrated bass reproduction — so the full frequency range of your mix is available for critical decisions.

Your monitors. Your sub.

iLoud Sub integrates with any monitoring system via flexible analog and digital connection options. ARC X calibration ensures the sub and your monitors work as a unified, time-aligned system — regardless of brand, model, or configuration.

Calibration built for the low end

Bass calibration requires more than broadband room correction. ARC X handles subwoofer-specific time-alignment, crossover management, and low-frequency room analysis — so the full-range result is as accurate as the sum of its parts.

Full-range performance. Minimal footprint.

iLoud Sub delivers professional low-frequency extension in an exceptionally compact form factor — designed for the desktop and nearfield environments where most modern production happens.

Effortless studio integration

The smallest studio subwoofer footprint on the market. Connect, run ARC X, and setup is complete. iLoud Sub offers the easiest way to achieve a truly professional monitoring experience.

Better mixes, everywhere

When your monitoring system reveals the full spectrum accurately, your mixes translate flawlessly from cars to theaters. Balanced, reliable sound from bottom to top.

Ready for immersive

Immersive production is increasingly important across music, film, gaming, and broadcast. iLoud Sub integrates naturally into multichannel workflows and serves as a foundation for larger systems calibrated with ARC X Immersive.
