Short answer: the Edifier MR4. It ranks #72 of 108 powered bookshelf speakers by sound quality, rated 3.5/5, at $169.99; the Fluid Audio FX50 V2 ranks #103, rated 2.7/5, and costs $298, so there is not much of a tradeoff to weigh.
The Edifier MR4 is the more accurate pick. A budget desktop monitor pair with balanced TRS inputs, tone controls and a front headphone jack. Its measured preference score, a predictor of how neutral it sounds, is 3.25 against 1.80 for the Fluid Audio FX50 V2. It keeps a wired aux input, which the Fluid Audio FX50 V2 lacks. The catch: 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: A coaxial studio monitor with balanced inputs, boundary controls and flexible mounting for compact installs. 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.
