These are not really the same size class, and that is the honest framing here. The Midiplus MI3 II ranks #47 of 48 powered bookshelf speakers by sound quality at $139; the Klipsch ProMedia Lumina ranks #4 of 8 powered subwoofer and satellite combo speakers by sound quality at $379.99.

The case for the Midiplus MI3 II: Compact desktop speakers with Bluetooth, analog inputs and a treble adjustment for a basic computer setup. The tradeoff: Preference scores of 0.99 standalone and 3.84 with an ideal subwoofer are poor.
The case for the Klipsch ProMedia Lumina: A desktop 2.1 system with horn tweeters, a separate subwoofer for real bass, tiltable stands, app control, and USB-C plus Bluetooth. Watch for: The review reports treble elevated about 3-5dB when aimed straight at the listener; some toe-out can reduce the brightness.
One note: the Midiplus MI3 II is discontinued and no longer widely available new. The Midiplus MI3 II’s replacement, the Midiplus MI3 II V2, is rated 2.5/5 at $139.
Buy the Midiplus MI3 II ($139) for a powered bookshelf speaker; the Klipsch ProMedia Lumina ($379.99) suits a powered subwoofer and satellite combo speaker instead.
