Open Box IK Multimedia iLoud Sub 200W Powered Subwoofer Level 1

Achieving accurate low end is one of the hardest things to achieve in a modern studio, especially if space and placement are limited. The IK Multimedia iLoud Sub is built to solve that problem by extending monitoring systems into the lowest octaves without adding boom, blur or guesswork. ARC X integration calibrates the sub and your connected monitors to the room, then stores the correction in the hardware so your playback stays consistent session to session. Add 200W peak power for real headroom, a 25Hz–150Hz frequency response and flexible USB, analog and Bluetooth connectivity, and you have a compact powered subwoofer that behaves like a serious studio tool. Compact enough to fit where traditional subs cannot, the iLoud Sub is optimized to integrate cleanly into modern production setups.

Phase-Coherent Bass With ARC X Room Calibration

What sets the iLoud Sub apart is how precisely it integrates with the rest of your monitoring system. A linear-phase crossover and time-coherent design ensure that low frequencies align naturally with your main speakers, avoiding the phase smear and uneven response common with compact subwoofer setups. Built-in ARC X compatibility allows the subwoofer and connected monitors to be calibrated together as a single system, correcting room-related issues at the source. ARC X goes beyond basic room correction by combining acoustic calibration with intelligent tuning and flexible voicing tools. Powered by IK’s VRM technology, it adapts your monitoring system to the realities of your space, helping mixes translate more consistently across different playback environments. The result is tighter bass, clearer imaging and mixes that translate more reliably across headphones, cars and larger playback systems.

High-Power Performance in a Compact Enclosure

Despite its small footprint, the iLoud Sub delivers serious output thanks to a 200W peak power amplifier paired with a custom 6.5" aluminum woofer and dual passive radiators. This design provides clean headroom and controlled dynamics while maintaining clarity at higher listening levels. With a 25Hz–150Hz frequency response, the sub fills in the lowest registers that compact monitors simply cannot reproduce, adding weight and depth without masking detail. It is a performance-focused solution for producers who need full-range monitoring without dedicating space to a large-format sub.

Flexible Connectivity And Modern Studio Workflow

Designed for today’s hybrid studios, the iLoud Sub offers USB audio connectivity, balanced XLR and unbalanced RCA I/O and Bluetooth for quick referencing from mobile devices. USB functionality allows it to operate as an audio interface, while onboard controls and software integration make setup and calibration straightforward. Whether paired with compact nearfields, immersive desktop rigs or portable production setups, IK Multimedia's iLoud Sub completes the monitoring picture with accuracy, control and confidence—so every low-frequency decision feels musical, intentional and trustworthy.
