Short answer: the Bowers & Wilkins Formation Flex. It ranks #11 of 24 powered bookshelf speakers by sound quality (rated 3.5/5); the Klipsch ProMedia Lumina ranks #15 (rated 3.3/5).
The case for the Bowers & Wilkins Formation Flex: ASR’s Klippel data gives a 6.43 predicted preference score with an ideal subwoofer and broad horizontal coverage. The catch: Standalone preference is only 3.69.
What the Klipsch ProMedia Lumina does well: 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. The catch: The review reports treble elevated about 3-5dB when aimed straight at the listener; some toe-out can reduce the brightness.

Bowers & Wilkins Formation Flex: £898 per pair Bowers & Wilkins eBay
Pros: ASR’s Klippel data gives a 6.43 predicted preference score with an ideal subwoofer and broad horizontal coverage. Its wireless stereo-pair capability and network streaming can suit a minimalist system without conventional source cables. The measured tonal result is more credible than judging sound quality from the compact wireless format alone.
Cons: Standalone preference is only 3.69. The response rises toward the treble, and the -3dB point is about 95Hz, so lower bass is substantially reduced even though the preference model’s separate LFX metric is 62Hz. Those two bass metrics are not interchangeable. A stereo pair is costly, and the lack of conventional analog input limits system flexibility.

Klipsch ProMedia Lumina: $299.99 per pair Amazon eBay
Pros: 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. Measured bass extension of 46Hz (-3dB).
Cons: 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.
