Short answer: the Genelec 8320A. It ranks #8 of 68 powered bookshelf speakers by sound quality, rated 4.5/5, at $1,700; the KEF LS50 Wireless II ranks #14, rated 4.3/5, and costs $2,999.99, so there is little reason to consider the other one.
On the Genelec 8320A side: The Directivity Control Waveguide and die cast aluminum Minimum Diffraction Enclosure produce a listening window smoothness score of 0.53 and a low frequency alignment Q of just 0.227, the cleanest, least resonant bass rolloff of any speaker in this whole batch. Set against that: On axis deviation measures 0.169dB average, decent but not class leading next to the AsciLab and Audio Smile entries in this batch.
What the KEF LS50 Wireless II offers: Uni-Q coincident driver array (130mm aluminum woofer with a 25mm MAT dome tweeter mounted at its acoustic center) gives excellent, consistent off-axis dispersion, measuring the tightest directivity spread of this batch alongside a smooth listening-window response. The tradeoff: Primary/Secondary architecture means one speaker handles every input while the other depends on a wireless or wired Ethernet link back to it - placement is less flexible than a fully symmetric pair.
Buy the Genelec 8320A. It is rated higher for sound quality than the KEF LS50 Wireless II and costs less, so only choose the other one for a particular feature it does better.

Genelec 8320A: $1,700 per pair B&H Photo Video eBay
Pros: A measured 1.6dB span from 300Hz to 5kHz and preference scores of 5.52 standalone and 8.04 with an ideal subwoofer support accurate close-range monitoring. The waveguide helps control the balance between direct and reflected sound. GLM room calibration is useful for matching levels and placement in a compact setup. Measured bass extension of 67.4Hz (-3dB).
Cons: The -3dB point is about 67Hz, making a subwoofer important for lower bass and giving the larger 8330A a practical advantage without one. Calibration hardware is sold separately. The small woofer limits its intended listening distance and bass output; a favorable response-fit parameter is not evidence that it has uniquely well-damped bass or unusually high headroom.

KEF LS50 Wireless II: $2,999.99 per pair Amazon KEF Crutchfield eBay
Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.
