These sit in different size classes, so this is not a straight ranking comparison. The M-Audio BX3 ranks #39 of 48 powered bookshelf speakers by sound quality at $99.99; the Klipsch ProMedia Lumina ranks #4 of 8 powered subwoofer and satellite combo speakers by sound quality at $379.99.
Why pick the M-Audio BX3: A budget desktop pair with balanced, RCA and aux inputs, a headphone output and tone controls to adjust for placement. The catch: ASR’s data gives only 2.04 standalone and 5.18 with an ideal subwoofer.
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. The catch: The review reports treble elevated about 3-5dB when aimed straight at the listener; some toe-out can reduce the brightness.
Buy the M-Audio BX3 at $99.99 if you want a powered bookshelf speaker. Buy the Klipsch ProMedia Lumina at $379.99 if you want a powered subwoofer and satellite combo speaker instead.
