The iLoud MTM is a compact active studio monitor. It measures 264x160x130mm and weighs only 2.5 kg. The iLoud MTM features a linearisation system that provides real-time performance enhancement for superior sound. The special design ensures optimal, even sound dispersion, a prerequisite for good acoustics. The compact size means it can fit virtually anywhere. The rubber base allows the speaker to be placed horizontally. The iLoud MTM can be tilted up to 20 degrees when placed on the table.

There are three calibration settings to choose from. IK’s proprietary ARC calibration system compensates for room acoustics using the measurement microphone.

With a total power of 100 W, the maximum sound pressure level is 103 dB. Thanks to the on-board DSP, the speaker sounds natural and realistic. It produces solid bass notes.

The speakers look like three-way monitors, but in fact they have a two-way/three-speaker setup, so they include two midrange and one tweeter. This design provides a sound that minimises ear fatigue. Other companies-such as Genelec and Pioneer use coaxial designs, with the tweeter in the centre of the woofer. For the iLoud MTM the mid-bass drivers are located on either side of the tweeter to provide a similar design and effect.

The woofers are called midrange, so you might think that the bass is not intense enough. In fact, they are designed with a bass extension up to 40 Hz and use IK’s Physical Response Linearization (PRL) system to ‘achieve a balanced and distinct bass response’.

Automatic calibration

IKM boasts that the speakers have a completely flat, neutral response, but in fact the frequency response can be calibrated to suit the room, so this means they provide accurate, flat sound regardless of the room.

These adjustments are very easy to make on MTM studio monitors. Simply connect the supplied ARC reference microphone to the back of the speakers and place it in the desired listening position. Press and hold the button and each speaker will immediately calibrate itself to try to provide a response that compensates for the room acoustics. The process takes less than 30 seconds. Of course, for perfect acoustics, it is essential to perform acoustic treatment of the walls of your room, especially in a studio. Special sound absorbing panels and diffusers, specially designed for acoustic purposes, are needed. Only with the right studio acoustics can expected sound engineering content be produced that sound ideal in any room.



We tested the speakers in a very small home studio. Fortunately, the acoustics of the studio were ideal, with leather membrane acoustic absorption panels and QRD diffusers on the walls. The compact IK Multimedia monitors sounded subdued compared to the width and depth of the larger, three-way Dynaudio Core 59 monitors, although there was no shortage of punchy bass. We heard extended tones, silky smooth, tight mids and controlled bass. Comparing them to the much cheaper JBLs, the MTMs are much more defined in the midrange.


This small pair of studio monitors is not at all inferior in sound compared to the larger models. Its size makes it easy to fit into even the smallest studios. The sound is absolutely right for studio work, with a sufficiently neutral tone. The soundstage is a little less wide than on the larger monitors, but that’s not a big problem. Bass was controlled. The calibration system can be used to further optimise the sound. All in all, this is a great little speaker that we heartily recommend to everyone.
