Short answer: the IK Multimedia iLoud MTM MKII. It ranks #22 of 100 powered bookshelf speakers by sound quality (rated 4.2/5) at $699.99 and is still sold new; the Midiplus MI5 II ranks #90 (rated 3.0/5) and is discontinued, so it is only an option used. The Midiplus MI5 II’s replacement, the Midiplus MI5 II V2, is rated 3.1/5.
The IK Multimedia iLoud MTM MKII is the more accurate choice. 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. Its measured preference score, a predictor of how neutral it sounds, is 5.22 against 2.24 for the Midiplus MI5 II. Watch for: Some excess treble remains in the native tuning.
What the Midiplus MI5 II does well: Balanced inputs, Bluetooth and a powered-pair format offer useful connectivity. It keeps a wired aux input, which the IK Multimedia iLoud MTM MKII lacks. The catch: The 2.24 standalone and 4.53 ideal-subwoofer scores show significant problems above the bass region.
Buy the IK Multimedia iLoud MTM MKII. It is rated higher for sound quality and still sold new, while the Midiplus MI5 II is discontinued.

IK Multimedia iLoud MTM MKII: $699.99 per pair Amazon eBay
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.

Midiplus MI5 II: $169 per pair Discontinued eBay
Newer model: the Midiplus MI5 II V2, ranked higher, estimated 3.1/5.
Same family: the Midiplus MI3 II (smaller bookshelf, rated 2.4/5).
Pros: Balanced inputs, Bluetooth and a powered-pair format offer useful connectivity. The measured -3dB point is around 54Hz, so it reaches lower in the bass than some compact monitors.
Cons: The 2.24 standalone and 4.53 ideal-subwoofer scores show significant problems above the bass region. A large 9.4dB midrange response span and listening-window narrow-band deviation of 0.644 indicate substantial coloration even though the overall response slope is fairly mild. A subwoofer cannot fix those irregularities. Amplifier-power specifications do not establish clean output. Discontinued.
