Short answer: the IK Multimedia iLoud MTM MKII for better sound quality, the Adam Audio A4V for the lower price. The IK Multimedia iLoud MTM MKII ranks #20 of 64 powered bookshelf speakers at $799.99. The Adam Audio A4V ranks #48 at $599.99, $200 cheaper.
What the IK Multimedia iLoud MTM MKII offers: Compact MTM layout (two 3.5” midwoofers flanking a 1” tweeter) powered monitor rated at 100W per speaker with XLR input, sold as a pair with an ARC room-correction microphone included. Well-suited to nearfield desktop use, with linearity good enough for mixing or mastering. The bundled auto room-correction mic is genuinely effective - in testing it resolved specific room resonance peaks around 150Hz and 220Hz, making the midrange sound noticeably more lifelike. Back-panel switches allow desktop vs. free-field placement plus treble and bass trim. Harmonic distortion is good at a moderate 86dB output, appropriate for a speaker of this size. Watch for: Native treble tuning still runs about 3dB hot on-axis; the back-panel -3dB treble switch overcorrects, and roughly -1.5dB via external EQ works better. Vertical MTM lobing means staying within about 20-25° of the tweeter axis, or the upper-midrange to treble transition suffers significant suckout - the speaker should never be laid on its side unless the tweeter is pointed directly at the listener, or comb filtering results. Bass falls off sharply below its F3 of 51Hz (F10 45Hz), so a subwoofer is needed for anything lower. Multitone distortion rises sharply at 96dB/1m, and the reviewer recommends not exceeding about 86dB for extended listening at any distance - broadband output for the pair tops out around 94dB at 1 meter, with dynamic range essentially collapsing approaching 102dB. Horizontal directivity narrows with frequency rather than staying constant. Adding a subwoofer with an 80Hz crossover doesn’t meaningfully improve the distortion headroom, even though it does extend the low end.
What the Adam Audio A4V offers: Compact current-generation monitor with an X-ART tweeter, onboard DSP, room controls and Sonarworks integration. ASR data shows good on-axis smoothness (0.132), a nearly neutral +0.23dB/octave slope and a 5.43 preference score with a subwoofer. Watch for: Measured bass extension is only 52Hz and the raw preference score falls to 3.02 without a subwoofer. Directivity-index consistency is middling at 3.77, and its analog-only XLR/RCA audio inputs omit USB and S/PDIF.
Buy the IK Multimedia iLoud MTM MKII if sound quality matters more than the price. Buy the Adam Audio A4V if the price matters more than sound quality.
If sound quality matters at all to you, skip the Adam Audio A4V. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
