IK Multimedia has announced the iLoud Sub, a new studio subwoofer designed to deliver deep, accurate, and tightly controlled low end in the smallest footprint available today. The release marks the latest expansion of IK’s respected iLoud monitor line and brings advanced room correction and automatic calibration to studios of any size.
iLoud Sub is the only subwoofer that can automatically calibrate itself and any connected monitors using ARC X technology. The system works with monitors of any brand, providing balanced, reliable sound across the entire frequency range from bottom to top. For modern producers, engineers, and hi fi listeners, the result is greater confidence in mixing decisions and a more faithful listening experience.
iLoud Sub at a Glance
- Small footprint that fits into any studio without rearranging equipment
- Bass extension down to 25 Hz for modern low end needs
- ARC X room correction for perfect system alignment
- Automatic setup for fast and accurate calibration
- Seamless integration with monitors of any brand
- Controlled, musical low end that translates smoothly across playback systems

Big Bass, Small Footprint
iLoud Sub was engineered to deliver full range clarity while maintaining a natural balance in the listening environment. Despite its compact size, it provides a powerful and musical response that extends to 25 Hz. This makes it a practical solution for small rooms where traditional subs would be difficult to position.
ARC X: Smarter Room Correction
Using ARC X, iLoud Sub analyzes the acoustics of the room and calibrates both the subwoofer and connected monitors. The process ensures a flat and balanced response so mixes translate consistently, whether they are played in a car, a theater, or a living room. The calibration works with speakers of any make or model.
This delivers:
- A natural, balanced response across the entire listening spectrum
- Effortless correction for monitors from any brand
- Mixes that translate reliably across multiple environments
With ARC X, setup requires only a connection and a quick calibration run.

Precision Alignment
iLoud Sub debuts ARC X’s newest feature, automatic subwoofer setup. The system calibrates and time aligns the sub with the main monitors to extend the system’s frequency range while preserving overall balance. Low end becomes more accurate and more revealing without introducing muddiness or masking.
Expect:
- Clear detail in kicks, bass lines, and sound design elements
- A consistent low end that improves translation
- Fuller bass that supports the entire mix rather than overpowering it
Premium Components for Maximum Musicality
- 6.5 inch high performance aluminum driver
- Dual 6.5 inch passive radiators for deeper extension
- 200 W peak power amplification
- Frequency response down to 25 Hz
The result is low end that is powerful yet controlled, warm yet clearly defined.
Flexible Connectivity
The iLoud Sub supports a wide range of studio workflows with both wired and wireless options.
Connections and control:
- XLR and RCA analog inputs and outputs
- USB digital audio input
- High quality Bluetooth streaming
- Full system calibration with ARC X software

A Meaningful Upgrade for Any Small Studio
