Short answer: the Edifier S2000MKIII for better sound quality, the Fluid Audio FX50 V2 for the lower price. The Edifier S2000MKIII ranks #29 of 64 powered bookshelf speakers at $699.99. The Fluid Audio FX50 V2 ranks #58 at $149, $550.99 cheaper.
What the Edifier S2000MKIII offers: Spinorama’s digitized measurements show unusually deep extension for a powered bookshelf speaker: 40.5Hz at -3dB and 37Hz at -6dB. Its preference score is 3.58 without a subwoofer and 5.34 with one, placing it just above the KRK Classic 5 and Edifier MR4 on the same with-subwoofer measure. It also accepts digital input up to 24-bit/192kHz. Watch for: The Spinorama record is low-quality data digitized from a scanned graph rather than an independent Klippel measurement, so the score carries more uncertainty. Frequency deviation is 4.0dB, predicted in-room smoothness is only 0.107, and the response needs substantial EQ around 1kHz and 3.3kHz to approach neutrality.
What the Fluid Audio FX50 V2 offers: Current 90W coaxial monitor with DSP boundary controls, balanced inputs, front port and wall/ceiling mounting points. The point-source geometry gives symmetrical radiation and flexible vertical or horizontal placement. Watch for: The local Spinorama snapshot is weak at 0.92 raw and 3.53 with a subwoofer despite 58Hz extension, indicating substantial tonal problems. It is better suited to correction-heavy or immersive monitoring than neutral plug-and-play listening.
Buy the Edifier S2000MKIII if sound quality matters more than the price. Buy the Fluid Audio FX50 V2 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Fluid Audio FX50 V2. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
