IK Multimedia iLoud Sub Compact Powered Subwoofer

Every time you finalize a mix on monitors without a proper subwoofer, you're leaving a massive chunk of the frequency spectrum completely unheard. The IK Multimedia iLoud Sub is a compact powered studio subwoofer that fills in those blanks with deep, accurate low-end extension down to 25 Hz, all in the smallest footprint on the market. Paired with ARC X's automatic room calibration, it makes your entire monitoring system more precise and reliable — without taking up your entire desk.

Maximum Bass, Minimum Space

Most studio subwoofers come with a side of existential dread when you realize they're bigger than your mixing chair. The iLoud Sub throws that convention out the window. Compact enough to slide into any desktop studio without sacrificing a single piece of furniture, it still delivers full-range low-end that reaches down to frequencies most monitors can only dream about. This is what it sounds like when engineering actually solves the problem instead of just making the box smaller.

25 Hz Deep Bass Extension: Powered by a 6.5-inch high-performance aluminum driver and dual 6.5-inch passive radiators, the iLoud Sub extends your monitoring system's low-end response all the way to 25 Hz — letting every kick drum, sub-bass, and rumbling synth layer reveal exactly what it's actually doing in your mix.
200 W Peak Power Amplification: Beneath its compact exterior sits a seriously capable amplifier stage that delivers tight, controlled, and musical low-end performance. This isn't bass that blooms or blurs — it's bass that behaves, giving you the power you need without the mud you don't.
Smallest Studio Subwoofer Footprint on the Market: Whether your studio is a professionally treated room or a spare bedroom, the iLoud Sub integrates without demanding a redesign. It occupies only a fraction of the space traditional subwoofers require — a very polite houseguest with very impressive credentials.

ARC X: Your Room Just Got Smarter

Rooms are acoustically messy. Standing waves, reflections, and frequency build-ups don't care how much you paid for your monitors — they'll color your sound anyway. ARC X is IK Multimedia's answer to all of that, and it's baked directly into the iLoud Sub. Rather than spending hours manually tweaking crossover points and phase alignment with a prayer and a pink noise generator, ARC X does the heavy lifting automatically. One measurement session, and your entire monitoring system — regardless of brand — is calibrated, time-aligned, and telling the truth.

Automatic Room Correction and Monitor Calibration: ARC X's advanced DSP algorithm analyzes your listening environment and applies precise correction across the full frequency spectrum, flattening your system's response so your mixes translate faithfully — from car speakers to theater systems to earbuds.
Universal Monitor Integration: The iLoud Sub doesn't discriminate. It automatically integrates and time-aligns with virtually any nearfield monitor brand, including third-party speakers, expanding their frequency range without disrupting their tonal balance. Your existing monitors just got an upgrade they didn't know they needed.
Automatic Subwoofer Setup: ARC X's newest feature takes subwoofer setup — historically a patience-destroying exercise in trial and error — and automates the entire process. Connect, run ARC X, and your sub is perfectly calibrated. That's the whole story.

Precision, Flexibility, and a Setup That Won't Make You Cry

Modern music production lives or dies in the low end — and the iLoud Sub is built to make sure yours doesn't. Kicks need weight. Bass lines need definition. Sub layers need to sit in the mix without swallowing everything around them. Whether you're working in a desktop home studio, a professional production room, or a compact immersive setup, the iLoud Sub holds its own. It pairs naturally with IK Multimedia's iLoud lineup but works just as well with any 3-to-7-inch nearfields you're already running.

Tight, Accurate, Musical Low-End Response: Every detail in your kick drums, bass lines, and sound design elements comes into sharp focus. Low-end balance stops being a guessing game and starts being a matter of precision.
Full-Range Clarity Without Midrange Interference: Deep doesn't have to mean muddy. The iLoud Sub delivers powerful bass extension that stays in its lane — warm and defined without clouding the midrange or throwing off your mix's translation.
Wired and Wireless Connectivity for Any Studio Workflow: XLR and RCA analog inputs and outputs, a USB digital audio input, and high-quality Bluetooth streaming ensure the iLoud Sub fits into any monitoring setup without friction. However, your studio is wired — or isn't — it connects.

Full-Range Monitoring Finally Done Right

The IK Multimedia iLoud Sub proves you don't have to choose between size and performance. This compact studio subwoofer delivers professional-grade low-end accuracy, automatic room correction via ARC X, and enough flexibility to feel at home in just about any studio setup. If your mixes have been lacking depth, losing translation, or quietly fibbing about what's going on below 80 Hz, the iLoud Sub is the missing piece of your monitoring chain — no furniture rearrangement required.
