Short answer: the Presonus Eris E5. It ranks #51 of 67 powered bookshelf speakers by sound quality, rated 3.3/5, at $109.99; the Fluid Audio FX50 V2 ranks #64, rated 2.7/5, and costs $149, which makes this an easy call rather than a real tradeoff.
Why pick 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. Watch for: Scores of 1.80 standalone and 4.42 with an ideal subwoofer indicate poor native tonal accuracy.
Why pick the Presonus Eris E5: Balanced XLR/TRS and RCA inputs plus placement adjustment make the original Eris E5 easy to connect to studio or consumer sources. The tradeoff: A fuller bass balance is not necessarily neutral.
Buy the Presonus Eris E5. It is rated higher for sound quality than the Fluid Audio FX50 V2 and costs less, so there is no real case for the other one.

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.

Presonus Eris E5: $219.98 per pair Amazon eBay
Pros: Balanced XLR/TRS and RCA inputs plus placement adjustment make the original Eris E5 easy to connect to studio or consumer sources. Existing listening notes describe a fuller low end than some small, bass-light monitors, which may suit casual nearfield listening.
Cons: A fuller bass balance is not necessarily neutral. Placement adjustment is useful, but it does not replace a properly integrated subwoofer for deep-bass monitoring.
