Short answer: the KEF LSX II LT, because the Edifier S1000MKII has no independent measurements behind it. The S1000MKII offers a high resolution digital input up to 192kHz/24bit, but no independent measurements exist. The LSX II LT’s coaxial driver spreads about +/-60 degrees each way for a wide sweet spot, though small drivers make it SPL-limited: bass compression around 88-92dB/1m and multitone distortion crossing 3% near 96dB.
What the KEF LSX II LT gets right: 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 catch: 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.
Buy the KEF LSX II LT. It is rated higher for sound quality than the Edifier S1000MKII and costs less, so only choose the other one for a particular feature it does better.

KEF LSX II LT: $479.99 per pair Amazon eBay
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 S1000MKII: $499.99 per pair Amazon eBay
Pros: A self-powered stereo pair with optical, coaxial and analog inputs, plus high-resolution digital support, makes source switching unusually simple. Consumer Reports rates its sound accurate and detailed, so it is a strong one-box alternative to separate amplifier-and-speaker systems for nearfield or small-room listening.
Cons: High-resolution input support is not a guarantee of perfect tuning, and the fixed internal amplification prevents the gradual upgrades possible with separates. These are mains-powered speakers rather than portable wireless speakers, and their size and left/right cabling need a planned desktop or stand setup. No independent measurements exist; reviews are limited to informal listening comparisons.
