Short answer: the Kali Audio SM-5 for better sound quality, the IK Multimedia iLoud MTM MKII for the lower price. The Kali Audio SM-5 ranks #4 of 42 powered bookshelf speakers at $3400. The IK Multimedia iLoud MTM MKII ranks #16 at $799.99, $2600.01 cheaper.
What the Kali Audio SM-5 gets right: True coaxial design with the tweeter mounted inside the midrange. The catch: Bass output is limited by the 5” mid-bass driver - don’t expect much excursion or high-SPL low end, though extension itself is reasonable for the size.
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. 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.
Buy the Kali Audio SM-5 if sound quality matters more than the price. Buy the IK Multimedia iLoud MTM MKII if the price matters more than sound quality.

Kali Audio SM-5: $3400 Sweetwater
Pros: True coaxial design with the tweeter mounted inside the midrange, and an unusually large waveguide that extends into the front baffle itself - directivity is excellent both horizontally (about +/-55 degrees) and vertically (+50/-40 degrees), so off-axis and low-seated listening positions still get a consistent tonal balance. Overall linearity is very good with in-room extension to about 40-45Hz. Distortion at 96dB is very low through the midrange, with only a mild, expected breakup around 3kHz tied to a small dip in the response there. Built-in DSP with free downloadable software lets you EQ each speaker individually for placement or room correction without an outboard processor, and the cabinet is wall-mountable - useful for surrounds, front heights, or tight desk setups. Compares very favorably to Kali’s own IN-8: similar raw linearity and distortion, but without the IN-8’s diffraction issues above 7kHz.
Cons: Bass output is limited by the 5” mid-bass driver - don’t expect much excursion or high-SPL low end, though extension itself is reasonable for the size. A mild high-Q resonance lingers around 2.5-4kHz in burst decay, though not strong. Instantaneous dynamic range is limited to roughly 96-102dB at 1m before compression sets in.

IK Multimedia iLoud MTM MKII: $799.99 Amazon
Pros: 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.
Cons: 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.
