IK Multimedia has announced the iLoud Sub, a compact studio subwoofer featuring automatic room calibration technology.
The unit extends low-frequency response down to 25Hz while claiming the smallest footprint of any studio subwoofer currently available. At its core is the company’s ARC X digital signal processing system, which automatically calibrates both the subwoofer and any connected monitors to compensate for room acoustics, regardless of speaker brand.
Key specifications include a 6.5-inch aluminium driver, dual passive radiators, and 200W peak amplification. Connectivity options span XLR and RCA analogue inputs/outputs, USB digital audio, and Bluetooth streaming.

The iLoud Sub integrates with nearfield monitors from 3 to 7 inches, including IK’s own iLoud Micro Monitor and MTM ranges. Setup is handled through the bundled ARC X software, which performs acoustic measurement and system time-alignment.
The subwoofer is priced at £599/€599 (excluding VAT) and includes the ARC X software suite plus measurement microphone. Pre-orders open 20 November, with shipping scheduled for early December.
