Short answer: the Edifier S1000MKII on measured sound quality, the Fluid Audio FX50 V2 on price. The Edifier S1000MKII ranks #56 of 67 powered bookshelf speakers, rated 3.3/5, at $499.99. The Fluid Audio FX50 V2 ranks #64, rated 2.7/5, at $149, $350.99 cheaper.
What the Fluid Audio FX50 V2 does well: The coaxial geometry and mounting provisions allow flexible physical orientation, while balanced inputs and boundary controls suit a compact studio installation. Watch for: Scores of 1.80 standalone and 4.42 with an ideal subwoofer indicate poor native tonal accuracy.
What the Edifier S1000MKII does well: A self-powered stereo pair with optical, coaxial and analog inputs, plus high-resolution digital support, makes source switching unusually simple. The catch: High-resolution input support is not a guarantee of perfect tuning, and the fixed internal amplification prevents the gradual upgrades possible with separates.

Fluid Audio FX50 V2: $298 per pair Fluid Audio eBay
Pros: The coaxial geometry and mounting provisions allow flexible physical orientation, while balanced inputs and boundary controls suit a compact studio installation. Bass reaches -3dB around 67Hz in ASR’s selected measurement.
Cons: Scores of 1.80 standalone and 4.42 with an ideal subwoofer indicate poor native tonal accuracy. Listening-window and predicted-room narrow-band deviations are both around 0.80, showing irregular sound for both the listener and room reflections. Coaxial construction does not guarantee smooth dispersion or neutral reproduction, and correction features should not be credited as a proven fix.

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.
