Short answer: the Edifier S1000W for the higher ranking, the KEF LSX II LT for the lower price. The Edifier S1000W ranks #15 of 24 powered bookshelf speakers at $599.99. The KEF LSX II LT ranks #17 at $449.99, $150 cheaper.
What the Edifier S1000W gets right: High resolution digital input up to 192khz/24bit.
On the KEF LSX II LT side: Coaxial (Uni-Q-style) driver keeps the tweeter centered in the midrange. The catch: Small drivers mean it’s SPL-limited: bass compression kicks in around 88-92dB/1m per speaker.
Buy the Edifier S1000W if the ranking matters more than the price. Buy the KEF LSX II LT if the price matters more than the ranking.

KEF LSX II LT: $449.99 Amazon
Pros: Coaxial (Uni-Q-style) driver keeps the tweeter centered in the midrange, giving wide and consistent dispersion both horizontally and vertically (about ±60° each) - a wide sweet spot for multiple seats or positions. The KEF Connect app provides genuinely useful DSP control: desk/wall boundary compensation, adjustable bass contour (standard/less/extra), treble trim, and subwoofer integration, letting you tune the sound to wherever it’s placed. Distortion at a moderate 86dB looks good for the speaker’s compact size. Tonal profile stays consistent from 0° to 30° off-axis, so side-seat listeners hear essentially the same balance as someone centered. Extensive connectivity for its size: HDMI, USB, optical, sub output, plus Wi-Fi/Bluetooth. Clearly outperformed the reviewer’s soundbars, including ones bundled with their own subwoofers, as a TV audio replacement.
Cons: Small drivers mean it’s SPL-limited: bass compression kicks in around 88-92dB/1m per speaker, and multitone distortion crosses the reviewer’s 3% threshold around 96dB - not intended for loud or large-room duty. F3 of 55Hz and F10 of 46Hz mean it loses much of its bass by around 50Hz; a subwoofer (controllable through the same app) is needed for real low end. Diffraction dips appear around 4-5kHz and again near 8kHz, likely tied to the tweeter housing or surround, giving a mild reduction in treble attack and sibilance. A possible port or enclosure resonance shows up around 800Hz in the rear-radiation measurements, though the reviewer wasn’t certain of the exact cause or whether it’s audible. No analog input on this LT variant, so a turntable can’t be connected directly - only the pricier standard LSX II model includes one.
