Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Bowers & Wilkins Formation Flex ranks #18 of 48 powered bookshelf speakers by sound quality; the Klipsch ProMedia Lumina ranks #4 of 8 powered subwoofer and satellite combo speakers by sound quality at $379.99.
The case for the Bowers & Wilkins Formation Flex: A compact wireless streaming speaker with AirPlay 2, Spotify Connect and Roon, which can pair as a cable-free stereo set. The catch: Standalone preference is only 3.69.
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. It keeps a wired aux input, which the Bowers & Wilkins Formation Flex lacks. The tradeoff: The review reports treble elevated about 3-5dB when aimed straight at the listener; some toe-out can reduce the brightness.
Worth knowing: the Bowers & Wilkins Formation Flex is discontinued, though it still ranks #18 of 48 powered bookshelf speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Bowers & Wilkins Formation Flex if you want a powered bookshelf speaker. Buy the Klipsch ProMedia Lumina if you want a powered subwoofer and satellite combo speaker instead.
