Older model: the IK Multimedia iLoud MTM (ranked lower, rated 4.1/5).

Same family: the IK Multimedia iLoud Micro Monitor Pro (smaller bookshelf, estimated 4.3/5).

Pros: Erin’s MKII measurements give a 2.2dB midrange span, a -3dB point around 53Hz, and preference scores of 5.22 standalone and 7.44 with an ideal subwoofer. The compact layout and included calibration microphone suit a close desktop setup. Existing tests show useful room-peak correction and good harmonic-distortion behavior at moderate levels. Measured bass extension of 52.7Hz (-3dB).

Cons: Some excess treble remains in the native tuning. The two-woofer MTM arrangement narrows the vertical listening window, so ear height and orientation matter. Multitone distortion rises strongly when pushed toward 96dB/1m; the review favors moderate listening levels, and a subwoofer does not eliminate all midrange output limits. These are MKII results, not measurements of the original MTM. Treble runs about 3dB hot on-axis; the rear -3dB treble switch overcorrects, and about -1.5dB of external EQ works better.

Onkyo GX-30ARC ranking card

Pros: HDMI ARC, USB-C, optical and analog inputs make it a convenient compact system for a desk or TV. Erin’s Klippel data gives a 3.69 standalone preference score and 6.42 with an ideal subwoofer. The midrange response spans 3.8dB, offering usable but not reference-level tonal performance.

Cons: The response rises toward the treble by about 0.48dB per octave. Bass reaches -3dB around 74Hz, not the lower LFX value used inside the preference model. Vertical listening position affects crossover balance. Its extensive connectivity does not compensate for response irregularities, and the published tonal data alone does not establish maximum clean output.
