IK Multimedia iLoud MTM vs Audioengine HD4

Last updated: October 1, 2026

Short answer: the IK Multimedia iLoud MTM MKII, if you are buying new. The IK Multimedia iLoud MTM ranks higher than the Audioengine HD4 (#30 vs #83 of 100 powered bookshelf speakers) but is discontinued; its replacement, the IK Multimedia iLoud MTM MKII, is rated 4.2/5 at $699.99 and is still sold new.

IK Multimedia iLoud MTM vs Audioengine HD4

The IK Multimedia iLoud MTM is the better-sounding option. ASR’s measurements of the original MTM give scores of 4.07 standalone and 6.26 with an ideal subwoofer, a 2.4dB midrange response span and a -3dB point around 53Hz. It has an adjustable EQ, which the Audioengine HD4 lacks. Watch for: The MTM arrangement makes listening height and orientation important, while bass below the low-50Hz region still needs support.

The case for the Audioengine HD4: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. It keeps a wired aux input, which the IK Multimedia iLoud MTM lacks. The catch: The compact cabinets suit close desktop listening rather than a large-room system.

Buy the IK Multimedia iLoud MTM MKII, the replacement for the discontinued IK Multimedia iLoud MTM; it is rated higher for sound quality than the Audioengine HD4.

IK Multimedia iLoud MTM ranking card

Newer model: the IK Multimedia iLoud MTM MKII, ranked higher, rated 4.2/5.

Pros: ASR’s measurements of the original MTM give scores of 4.07 standalone and 6.26 with an ideal subwoofer, a 2.4dB midrange response span and a -3dB point around 53Hz. The small cabinet, balanced input and calibration capability make it useful for close listening where larger monitors would be impractical. Measured bass extension of 50Hz (-3dB).

Cons: The MTM arrangement makes listening height and orientation important, while bass below the low-50Hz region still needs support. The native response is not as smooth as the best compact reference monitors. Exact compression ceilings and correction examples from the MKII review should not be assigned to this original version; its score describes tonal response, not maximum clean volume. Treble runs about 3dB hot on-axis; the reviewer found the rear -3dB switch too aggressive and preferred about -1.5dB of external EQ. Discontinued.

Audioengine HD4 ranking card

Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5) and the Audioengine HD6 (larger bookshelf, ranked higher, rated 3.3/5).

Pros: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. Its modest footprint is useful where larger studio monitors are impractical.

Cons: The compact cabinets suit close desktop listening rather than a large-room system. A separate subwoofer adds cost and space if deeper bass is a priority.
