Short answer: the Genelec 8330A if sound quality matters most, the KEF LSX II LT if price matters most. The Genelec 8330A ranks #7 of 100 powered bookshelf speakers, rated 4.5/5, at $2,250. The KEF LSX II LT ranks #35, rated 4.0/5, at $549.99, $1,700.01 cheaper.
The case for the KEF LSX II LT: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Watch for: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
The Genelec 8330A is the more accurate option. ASR’s measurements give a 2.3dB midrange response span and a -3dB point around 56Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.54 against 4.81 for the KEF LSX II LT. The catch: The listening-window response has more local variation than the 8030C or KH80 in the selected measurements, so DSP capability should not be mistaken for superior native neutrality.
Buy the KEF LSX II LT if the price is the priority over sound quality, or the Genelec 8330A if sound quality is the priority over the price.

KEF LSX II LT: $549.99 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 8330A: $2,250 per pair B&H Photo Video eBay
Same family: the Genelec 8320A (smaller bookshelf, ranked lower, rated 4.5/5), the Genelec 8340A (larger bookshelf, estimated 4.4/5) and the Genelec 8350A (larger bookshelf, estimated 4.5/5).
Pros: ASR’s measurements give a 2.3dB midrange response span and a -3dB point around 56Hz. Scores of 5.54 standalone and 7.79 with an ideal subwoofer indicate solid tonal accuracy, while deeper bass than the 8320A helps without a sub. GLM calibration, the waveguide and rounded aluminum enclosure make it a practical compact studio system. Measured bass extension of 55.7Hz (-3dB).
Cons: The listening-window response has more local variation than the 8030C or KH80 in the selected measurements, so DSP capability should not be mistaken for superior native neutrality. GLM calibration hardware costs extra. Small-driver bass headroom remains finite, and neither the modeled ideal-subwoofer score nor the fitted bass Q establishes maximum output or freedom from resonances.
