IK Multimedia iLoud Sub 8 inch Powered Studio Subwoofer

IK Multimedia iLoud Sub – compact active studio subwoofer built for producers and engineers working in rooms where low-end accuracy is the first thing to fall apart. A 6.5" aluminium driver with dual 6.5" passive radiators reaches down to 25 Hz with tight, defined response that no nearfield monitor in this price range can replicate on its own. The built-in ARC X room correction calibrates both the subwoofer and any connected satellite monitors simultaneously – regardless of brand – making this one of the few subs on the market that genuinely improves the entire monitoring chain rather than just adding more bass.

Room Correction That Changes How You Mix

Small rooms stack standing waves, load up corners, and deliver bass response that varies wildly from note to note. ARC X takes a measurement with the included mic, then automatically sets the crossover point, aligns phase, adjusts levels, and applies targeted EQ correction across the full system – sub and satellites together. The corrected, crossovered signal is distributed through the XLR outputs to your monitors, so the entire chain operates as a single, coherent system. The result: kick drums, bass lines, and sub-harmonic content you can actually trust, not estimate. Engineers stop second-guessing whether a mix will translate – once ARC X is dialled in, the room gets out of the way.

Desktop Footprint, No Compromises on Extension

At 244 × 250 × 283 mm and 7.1 kg, the iLoud Sub sits under a desk or on a shelf without rearranging the workspace. A Class-D amplifier rated at 160 W RMS / 200 W peak delivers a maximum SPL of 106 dB peak at 40 Hz. Connectivity covers balanced XLR and unbalanced RCA I/O, USB-B digital input at up to 96 kHz PCM, and Bluetooth (SBC/AAC). Manual crossover points of 50 Hz or 80 Hz are available, with automatic handling engaged whenever ARC X calibration is active. It extends any 3–7" nearfield monitoring system into a full-range setup without requiring a complete speaker overhaul.
