Short answer: the Edifier R1280DB for better sound quality, the Fluid Audio FX50 V2 for the lower price. The Edifier R1280DB ranks #35 of 64 powered bookshelf speakers at $159.98. The Fluid Audio FX50 V2 ranks #58 at $149, $10.98 cheaper.
What the Edifier R1280DB offers: Same drivers and cabinet as the ASR-measured Edifier R1280T (identical 4” woofer, same 4.9kg enclosure) plus Bluetooth and digital optical/coax inputs the R1280T doesn’t have. ASR’s measurements of that shared platform found the woofer handled a demanding bass-heavy track without bottoming out or audible distortion, and distortion stayed low and inaudible at a normal 86dB SPL listening level. Built-in remote and bass/treble tone controls, no separate preamp needed. Watch for: Shares the R1280T’s jagged on-axis response rather than a neutral one, with a woofer resonance around 5kHz and a tweeter peak near 10kHz that also show up in the directivity data. The reviewer’s raw impression of that platform was “a bit bass heavy and after a track or two, somewhat bright,” and recommends EQ correction; vertical listening window is narrow, so the tweeter needs to be angled toward the ears. Not quite as neutral sounding as the Edifier MR4.
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 R1280DB 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.
