Short answer: the Klipsch ProMedia Lumina. It ranks #15 of 24 powered bookshelf speakers by sound quality, rated 3.3/5, at $299.99. The Midiplus MI3 II ranks #23, rated 2.4/5, at $139, $160.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Midiplus MI3 II: Compact cabinets, Bluetooth, analog inputs and high-frequency adjustment can suit a basic desktop system. The tradeoff: Preference scores of 0.99 standalone and 3.84 with an ideal subwoofer are poor.
The case for the Klipsch ProMedia Lumina: The included powered subwoofer gives this compact desktop system a real low-bass advantage: the linked review reports F3 around 46Hz and F10 around 38Hz. Watch for: The review reports treble elevated about 3-5dB when aimed straight at the listener; some toe-out can reduce the brightness.
Buy the Klipsch ProMedia Lumina. It is rated higher for sound quality, and the $160.99 you would save on the Midiplus MI3 II does not close the gap.

The Two Speakers In Full
Midiplus MI3 II: $139 per pair eBay
Pros: Compact cabinets, Bluetooth, analog inputs and high-frequency adjustment can suit a basic desktop system. The measured -3dB point is about 67Hz, so missing bass is not its only differentiator from other tiny speakers.
Cons: Preference scores of 0.99 standalone and 3.84 with an ideal subwoofer are poor. High narrow-band deviations on-axis (0.938) and across the listening window (0.852) indicate pronounced response irregularities that can color voices and instruments. The fairly flat overall trend does not mean the response itself is smooth. A subwoofer or simple treble adjustment cannot resolve all of these problems.

Klipsch ProMedia Lumina: $299.99 per pair Amazon eBay
Pros: The included powered subwoofer gives this compact desktop system a real low-bass advantage: the linked review reports F3 around 46Hz and F10 around 38Hz. Tiltable stands, app control and lighting add practical desktop features. The existing review reports reasonable distortion for the system’s size. Measured bass extension of 46Hz (-3dB).
Cons: The review reports treble elevated about 3-5dB when aimed straight at the listener; some toe-out can reduce the brightness. Fixed-band app EQ is less flexible than parametric correction. Its separate subwoofer also means the system occupies more space than the satellites alone suggest.
