Short answer: the Fluid Audio FX50 V2, if you are buying new. The Midiplus MI5 II ranks higher than it (#97 vs #103 of 108 powered bookshelf speakers, 3.0/5 vs 2.7/5) but is discontinued, so only consider it used; the Fluid Audio FX50 V2 is still sold new at $298. The Midiplus MI5 II’s replacement, the Midiplus MI5 II V2, is rated 3.1/5 at $169.
The case for the Midiplus MI5 II: An inexpensive powered monitor pair with balanced inputs, Bluetooth and fairly deep bass for the size. It keeps a wired aux input, which the Fluid Audio FX50 V2 lacks. The catch: The 2.24 standalone and 4.53 ideal-subwoofer scores show significant problems above the bass region.
The case for the Fluid Audio FX50 V2: A coaxial studio monitor with balanced inputs, boundary controls and flexible mounting for compact installs. The tradeoff: Scores of 1.80 standalone and 4.42 with an ideal subwoofer indicate poor native tonal accuracy.
Buy the Fluid Audio FX50 V2 if you want one new; the Midiplus MI5 II is discontinued, so only look for it used.
