Short answer: the Edifier MR4. It ranks #48 of 67 powered bookshelf speakers by sound quality, rated 3.5/5, at $169.99; the Fluid Audio FX50 V2 ranks #64, rated 2.7/5, and costs $298, so there is not much of a tradeoff to weigh.
Why pick the Edifier MR4: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. The tradeoff: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend.
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. The catch: Scores of 1.80 standalone and 4.42 with an ideal subwoofer indicate poor native tonal accuracy.
Buy the Edifier MR4. It is rated higher for sound quality than the Fluid Audio FX50 V2 and costs less, which makes it the one to get unless you need something the other one does better.

Edifier MR4: $169.99 per pair Amazon eBay
Pros: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. Balanced TRS inputs and tone controls are practical at its price, and its response is more balanced than the measured R1280T. Measured bass extension of 79Hz (-3dB), with a measured sensitivity of 78dB.
Cons: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend. Listening-window response still has local irregularities, including lower-treble unevenness. The existing review reports rapidly increasing distortion and audible distress when pushed well above moderate desktop levels. No Bluetooth, and adding a subwoofer does not cure every output or tonal limitation.

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.
