IK Multimedia iLoud Sub

Ultra-Compact Studio Subwoofer with ARC Room Calibration

Bring the missing octave back into your mixes.

The IK Multimedia iLoud Sub is a professional ultra-compact studio subwoofer designed for producers, mixing engineers, content creators, composers and home studio owners who demand accurate low-frequency monitoring without sacrificing valuable studio space. Despite its remarkably small footprint, the iLoud Sub delivers deep, controlled bass down to 25Hz, allowing you to hear every detail of your mix with confidence.

Built around a high-performance 6.5″ aluminium woofer, dual passive radiators and powerful Class-D amplification, the iLoud Sub integrates seamlessly with virtually any nearfield monitor system while maintaining exceptional clarity, speed and musical accuracy.

What truly sets the iLoud Sub apart is IK Multimedia’s advanced ARC X room calibration technology. Using the included measurement microphone and software, the system automatically aligns and calibrates both the subwoofer and connected monitors, helping eliminate room-induced bass problems and delivering a more accurate listening environment.
