IK Multimedia iLoud Sub w/ARC X – Review

The IK Multimedia iLoud Sub is small on size, but BIG on bottom! Reaching all the way down to 25Hz, this subwoofer will expand your studio monitor only setup into a, basically, full-range audio system. Plus the iLoud Sub includes ARC X Room Correction software which will correct your speakers, room, and sub – so you can record, mix, master, and create audio that you know will translate well when played on other systems.

While the iLoud Sub is made for professional purposes, you could also use it for entertainment purposes, like gaming for example. The iLoud Sub has a USB input, so your computer can send digital audio directly to the subwoofer, no need for an audio interface.

Plus, the iLoud Sub also has Bluetooth connectivity, further enhancing it’s flexibility beyond professional audio uses only.

The iLoud Sub is small, but boast a big bottom end. The custom 6.5″ aluminum woofer effortlessly pushes frequencies as low as 25Hz! Paired with any small 3″-7″ speakers (studio monitors) will give you a “basically” full-range system that doesn’t take up a ton of space.

Also, with ARC X you can emulate other types of studio monitors and audio devices like Phones and TV’s – so with this relatively small setup you have all your bases covered, without needing to invest in several pairs of studio monitors to check your mix on.

The iLoud Sub also stores the ARC X correction, so no need to load up ARC X in your DAW every time you want to hear your audio the way it actually sounds, and not the way it’s being colored by the room.

I found the iLoud Sub and ARC X to be easy to use and setup. The iLoud Sub is well built and has weight to it (about 15 lbs). The iLoud Sub definitely increases the low-end you can hear and work with. Audio becomes more effortless sounding, much more rich and full, while still being punchy and articulate.

You can use the iLoud Sub with any brand of monitors, and it seamlessly drops right into your current monitor only setup.

If you have been wanting to add a sub to your setup, this is one you should consider.
