Short answer: the Cambridge Audio L/R S for better sound quality, the Klipsch ProMedia Lumina for the lower price. The Cambridge Audio L/R S ranks #4 of 23 powered bookshelf speakers at $549. The Klipsch ProMedia Lumina ranks #14 at $299.99, $249.01 cheaper.
What the Cambridge Audio L/R S offers: A 2-way active bookshelf pair built for near-field desktop use, with a 21mm aluminum tweeter and a 3-inch long-throw woofer on each speaker. Erin’s Audio Corner measured a very neutral on-axis response with good directivity control up through the 2-3kHz handoff to the tweeter, an F3 of about 57Hz and F10 of about 50Hz, and output held within roughly plus or minus 2.5dB from 80Hz to 20kHz. Horizontal dispersion of about plus or minus 60 degrees and a vertical window of about plus 30 to minus 20 degrees make it forgiving of off-center desktop seating. Two rear switches (a desktop-placement compensation switch and a near-wall/free-space switch) plus in-app DSP for room size, wall distance, and reflective surface type let you tune the in-room response rather than just hoping placement works out, and the reviewer noted an audible tightening of the bass moving between room-size settings. Rear connectivity includes RCA, optical digital, USB-C, and a dedicated subwoofer output. Watch for: 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. Each speaker’s Class D amplifier splits only 50W to the woofer and 50W to the tweeter, modest for the class. The DSP room-correction options are preset-based rather than a true microphone-measured calibration at the listening position, so results depend on picking settings that match your actual room.
What the Klipsch ProMedia Lumina offers: 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. Watch for: 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.
