Short answer: the KEF LSX II LT. It ranks #35 of 100 powered bookshelf speakers by sound quality, rated 4.0/5, at $549.99. The Edifier R2000DB ranks #78, rated 3.3/5, at $249.99, $300 cheaper, which does not close the gap in sound quality.
The KEF LSX II LT is the better-sounding option. The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. The catch: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
Why pick the Edifier R2000DB: Multiple analog inputs and optical connectivity make it convenient for a simple powered stereo system. The tradeoff: Listening impressions suggest a midrange-forward presentation.
Buy the KEF LSX II LT. It is rated higher for sound quality, and saving $300 with the Edifier R2000DB does not make up for the sound-quality gap.

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.

Edifier R2000DB: $249.99 per pair Amazon eBay
Pros: Multiple analog inputs and optical connectivity make it convenient for a simple powered stereo system. It can suit general desktop listening when source flexibility matters more than professional monitoring functions.
Cons: Listening impressions suggest a midrange-forward presentation. It is better suited to a simple home stereo setup than a studio workflow requiring balanced inputs.
