Short answer: the IK Multimedia iLoud MTM MKII. It ranks #22 of 100 powered bookshelf speakers by sound quality (rated 4.2/5); the Donner Dyna 3 ranks #97 (rated 1.8/5).
The IK Multimedia iLoud MTM MKII is the more accurate, deeper-bass 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 -0.06 for the Donner Dyna 3. Its bass reaches about 52.7Hz before falling 3dB, against 85Hz for the Donner Dyna 3. The catch: Some excess treble remains in the native tuning.
The case for the Donner Dyna 3: A low-cost powered desktop pair with several input options and a small footprint. It keeps a wired aux input, which the IK Multimedia iLoud MTM MKII lacks. The tradeoff: Erin’s Klippel measurements give a negative standalone preference score of -0.06 and only 3.24 with an ideal subwoofer.

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.

Donner Dyna 3 eBay
Pros: A low-cost powered desktop pair with several input options and a small footprint. It can provide basic close-range background playback without an external amplifier. Measured bass extension of 85.0Hz (-3dB).
Cons: Erin’s Klippel measurements give a negative standalone preference score of -0.06 and only 3.24 with an ideal subwoofer. The response spans 8.2dB from 300Hz to 5kHz, with large listening-window irregularities. Bass reaches -3dB around 85Hz, and the existing review reports distortion and compression limits. It is not a credible neutral studio monitor despite that style of marketing.
