Short answer: the Edifier S2000MKIII. It ranks #69 of 100 powered bookshelf speakers by sound quality, rated 3.5/5, at $594.99. The Fluid Audio FX50 V2 ranks #95, rated 2.7/5, at $298, $296.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Edifier S2000MKIII is the more accurate option. The available digitized response suggests substantial bass reach, with a -3dB estimate around 41Hz. Its measured preference score, a predictor of how neutral it sounds, is 4.24 against 1.80 for the Fluid Audio FX50 V2. Watch for: The 4.0dB midrange span and uneven predicted room response suggest meaningful coloration.
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.
Buy the Edifier S2000MKIII. It is rated higher for sound quality, and saving $296.99 with the Fluid Audio FX50 V2 does not make up for the sound-quality gap.

Edifier S2000MKIII: $594.99 per pair Amazon eBay
Older model: the Edifier S2000 Pro (ranked higher, rated 3.7/5).
Pros: The available digitized response suggests substantial bass reach, with a -3dB estimate around 41Hz. Scores are 4.24 standalone and 5.99 with an ideal subwoofer. Digital inputs and a self-contained stereo-pair format are convenient for general music listening. Digital input handles high-resolution audio up to 192kHz/24-bit.
Cons: The 4.0dB midrange span and uneven predicted room response suggest meaningful coloration. Favorable modeled EQ results should not be treated as the sound of the stock speaker or as proof that all dispersion issues are correctable.

Fluid Audio FX50 V2: $298 per pair Fluid Audio eBay
Older model: the Fluid Audio FX50 (ranked higher, rated 2.8/5).
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.
