Short answer: the Edifier R1700BT. It ranks #59 of 67 powered bookshelf speakers by sound quality, rated 3.2/5, at $219.99. The Fluid Audio FX50 V2 ranks #64, rated 2.7/5, at $149, $70.99 cheaper, which does not close the gap in sound quality.
The case for the Fluid Audio FX50 V2: The coaxial geometry and mounting provisions allow flexible physical orientation, while balanced inputs and boundary controls suit a compact studio installation. The catch: Scores of 1.80 standalone and 4.42 with an ideal subwoofer indicate poor native tonal accuracy.
Why pick the Edifier R1700BT: A compact powered pair with analog and Bluetooth connectivity for uncomplicated desktop listening. The tradeoff: Listening impressions suggest a bass-and-treble-forward balance rather than strict neutrality.
Buy the Edifier R1700BT. It is rated higher for sound quality, and the $70.99 saving on the Fluid Audio FX50 V2 is not enough to make up the difference.

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 R1700BT: $219.99 per pair Amazon eBay
Pros: A compact powered pair with analog and Bluetooth connectivity for uncomplicated desktop listening. Its self-contained design avoids the need for a separate amplifier.
Cons: Listening impressions suggest a bass-and-treble-forward balance rather than strict neutrality. Its analog and Bluetooth connections are less convenient for sources that require optical or HDMI input.
