Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Cambridge Audio L/R S ranks #4 of 48 powered bookshelf speakers by sound quality at $549; the Klipsch ProMedia Lumina ranks #4 of 8 powered subwoofer and satellite combo speakers by sound quality at $379.99.
What the Cambridge Audio L/R S does well: Compact desk speakers with very accurate sound, Bluetooth and optical and USB inputs, best for close listening. It supports aptX HD Bluetooth, which the Klipsch ProMedia Lumina lacks. The tradeoff: Maximum clean output is limited: Erin’s Audio Corner measured about 86dB before the onboard limiter engages around 96dB to protect the drivers, so this is a near-field or small-room speaker rather than one built to fill a living room.
The Klipsch ProMedia Lumina is the deeper-bass pick. A desktop 2.1 system with horn tweeters, a separate subwoofer for real bass, tiltable stands, app control, and USB-C plus Bluetooth. Its bass reaches about 46Hz before falling 3dB, against 57Hz for the Cambridge Audio L/R S. It keeps a wired aux input, which the Cambridge Audio L/R S lacks. 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 Cambridge Audio L/R S at $549 for a powered bookshelf speaker, or the Klipsch ProMedia Lumina at $379.99 for a powered subwoofer and satellite combo speaker instead.
