Short answer: the Genelec 8020D. It ranks #13 of 105 powered bookshelf speakers by sound quality, rated 4.4/5, at $1,390. The KEF LSX II LT ranks #36, rated 4.0/5, at $699.99, $690.01 cheaper, which does not close the gap in sound quality.
The 8020D is the more accurate small monitor. Audio Science Review’s Klippel measurements show a flat on-axis response from about 60Hz to 10kHz, with off-axis curves tracking closely, and it reaches 56Hz before falling 3dB. It takes balanced XLR input and has bass tilt and desk filters. It is analog only, and it is sold individually.
The LSX II LT is a complete wireless system. Its coaxial driver gives broad dispersion of about 60 degrees in every direction, and it adds streaming, HDMI and USB inputs and app placement settings. It reaches about 55Hz before falling 3dB, but its midrange spans 3.4dB and it compresses around 88 to 92dB at 1m. This LT version has no analog input.
Buy the Genelec 8020D. It is rated higher for sound quality, and the $690.01 you would save on the KEF LSX II LT does not close the gap.

KEF LSX II LT: $699.99 per pair Amazon eBay
Same family: the KEF LSX II (larger bookshelf, estimated 4.1/5), the KEF LS50 Wireless II (larger bookshelf, ranked higher, rated 4.3/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Erin’s measurements give preference scores of 4.81 standalone and 7.03 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. Horizontal and vertical dispersion both reach about ±60°, giving a broad sweet spot for more than one seat. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 84dB.
Cons: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors. The existing review finds bass compression around 88-92dB/1m and rising distortion at higher levels, so the small drivers suit close listening rather than a large room. This LT version has no analog input; a turntable cannot plug straight into it.

Genelec 8020D: $1,390 per pair B&H Photo Video eBay
Same family: the Genelec 8010A (smaller bookshelf, rated 4.5/5), the Genelec 8030C (larger bookshelf, ranked higher, rated 4.6/5), the Genelec 8040B (larger bookshelf, rated 4.3/5) and the Genelec 8050B (larger bookshelf, rated 4.4/5). See every Genelec 8000 and 8300 Series generation.
Pros: A compact waveguided monitor with balanced XLR input and placement filters, well suited to a small studio desk. Klippel measurements show a flat, well-behaved on-axis response from about 60Hz to 10kHz, with listening-window and early-reflection curves tracking closely, a sign of well-controlled directivity. Measured bass extension of 56Hz (-3dB).
Cons: Small size limits deep-bass reach and headroom. It lacks the GLM calibration of the SAM models, and the price is substantial for a compact analog-input monitor. Sound power starts rolling off around 500Hz to 1kHz as the small drivers begin to beam.
