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. The Avantone Pro Active MixCube ranks #99, rated 1.7/5, at $518, $181.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The IK Multimedia iLoud MTM MKII is the more accurate pick. 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 -3.58 for the Avantone Pro Active MixCube. Watch for: Some excess treble remains in the native tuning.
What the Avantone Pro Active MixCube does well: A deliberately bandwidth-limited single-driver monitor for checking midrange balance and mix translation. The catch: It is not a full-range music speaker.
Buy the IK Multimedia iLoud MTM MKII. It is rated higher for sound quality, and the $181.99 you would save on the Avantone Pro Active MixCube does not close the gap.

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.

Avantone Pro Active MixCube: $518 per pair B&H Photo Video eBay
Pros: A deliberately bandwidth-limited single-driver monitor for checking midrange balance and mix translation. The powered, sealed format, isolation pad and stand mounting make it useful as a secondary studio reference.
Cons: It is not a full-range music speaker. The measured -3dB point is around 297Hz, and scores of -3.58 standalone and 1.16 with an ideal subwoofer reflect severe bandwidth and response limitations for general listening. A subwoofer cannot restore the missing high-frequency coverage. This low general-purpose rank does not measure its usefulness for the specialist task of checking a mix.
