IK Multimedia has established itself with the iLoud philosophy: achieving reliable monitoring in a reduced format without sacrificing mix translation. The iLoud Sub continues this legacy by naturally complementing compact nearfield monitors, including models from 3 to 7 inches. Whereas many subwoofers limit themselves to simply "adding bass," this one aims for coherent integration thanks to the ARC X ecosystem: the correction doesn't stop at the subwoofer, it can also align connected satellites to restore a global balance closer to the mixing intent.
The iLoud Sub targets producers, mixers, and sound designers working in tight spaces but wanting to make confident decisions on the most challenging frequency range to judge: the low end. In home studios, it helps distinguish the real energy between kick and bass, control sub-harmonics, and avoid "phantom bass" created by the room. In post-production, it provides a more stable reading of impacts, ambiences, and LFE effects without requiring a heavy setup. Its small footprint also facilitates integration into stereo or compact immersive configurations when the goal is to improve bass clarity without completely reorganizing the control room.
The most decisive innovation in daily use is ARC X's "system" approach. Instead of merely adjusting level and crossover, the DSP calibration aims to tailor the response at the listening position to minimize room effects (peaks, dips, and resonances). The result: cleaner bass, a more coherent sub-to-satellites transition, and faster mixing decisions because you compensate less with EQ. The included ARC microphone simplifies the measurement process, and the software centralizes settings for easy recall across your sessions.
To reconcile small size with sub-bass extension, the iLoud Sub combines a 6.5-inch aluminum driver with two 6.5-inch passive radiators. This architecture helps achieve a frequency response down to 25 Hz while maintaining a discreet format, easier to place near a desk. The bass gains in control and clarity, which is especially useful for judging kick length, bass compression, or the actual sub level in a dense arrangement.
On the connection side, the iLoud Sub easily integrates into a classic monitoring environment via analog XLR and RCA inputs/outputs. For modern workflows, digital audio via USB-C allows direct connection suited to many production setups, while Bluetooth facilitates quick monitoring sessions (references, checking on another playback chain, or simple comparison). The automatic standby feature provides everyday comfort, particularly appreciated in home studios.
