Short answer: the IK Multimedia iLoud MTM MKII for better sound quality, the Topping MA4 for the lower price. The IK Multimedia iLoud MTM MKII ranks #20 of 58 powered bookshelf speakers at $799.99. The Topping MA4 ranks #33 at $449, $350.99 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 Topping MA4 offers: Topping’s first loudspeaker, notable for deliberately skipping the DAC and DSP the company built its reputation on. A single balanced XLR input feeds a fully analog crossover, which Topping argues keeps the signal path free of extra conversion stages. The bass alignment measures a low Q of 0.452, rolling off cleanly rather than peaking, and extension reaches 49.8Hz at -3dB for a compact 4 inch two way, at a genuinely low price. Watch for: On axis deviation measures 0.503dB average, on the rougher side for this catalog, and listening window smoothness sits at a moderate 0.44. No USB, Bluetooth, or digital input of any kind, an unusual limitation from a DAC company and a real constraint if you want a simple all in one desktop setup. This is Topping’s first speaker with no track record in the category, and current US retail availability is limited, most confirmed stock is through European or Indian resellers.
