Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Monoprice Monolith MM-3 ranks #28 of 48 powered bookshelf speakers by sound quality at $299.99; the Klipsch ProMedia Lumina ranks #4 of 8 powered subwoofer and satellite combo speakers by sound quality at $379.99.
Why pick the Monoprice Monolith MM-3: A compact desktop pair with Bluetooth, analog inputs, a headphone jack and angled stands. It supports aptX Bluetooth, which the Klipsch ProMedia Lumina lacks. The tradeoff: Its measurements and rating are for the ports plugged; left stock, the bass has a boomy peak and the midrange has more resonances.
What the Klipsch ProMedia Lumina does well: A desktop 2.1 system with horn tweeters, a separate subwoofer for real bass, tiltable stands, app control, and USB-C plus Bluetooth. The tradeoff: The review reports treble elevated about 3-5dB when aimed straight at the listener; some toe-out can reduce the brightness.
Buy the Monoprice Monolith MM-3 ($299.99) for a powered bookshelf speaker; the Klipsch ProMedia Lumina ($379.99) suits a powered subwoofer and satellite combo speaker instead.
