Short answer: the KEF LSX II LT is the more refined active speaker system, while the Edifier S1000W wins on connection variety. KEF’s coaxial driver maintains more consistent sound across seats and has measured 55Hz -3dB bass, HDMI, USB-C, Wi-Fi, optical, Bluetooth, and app-based placement and subwoofer controls.
The S1000W offers Wi-Fi plus two RCA inputs, optical and coaxial digital inputs, making it unusually accommodating of old and new sources. KEF’s response is not perfectly neutral and bass compresses near loud playback, but it has independent measurements behind its performance. Edifier’s high-resolution input support does not by itself establish acoustic accuracy.
Buy the Edifier S1000W if you need its unusually broad mix of analog and digital source inputs.
Buy the KEF LSX II LT for HDMI-based TV use, app adjustment, and a more measured acoustic foundation.
