The Two Speakers In Full
Midiplus MI3 II V2 eBay
Older model: the Midiplus MI3 II (rated 2.4/5).
Pros: The second generation of Midiplus’s smallest powered monitor pair: a 3.5” woven fiberglass woofer and a 1” silk dome tweeter behind a metal mesh guard in each wooden cabinet, driven by 2x 25W of Class D power. It adds balanced 1/4” TRS inputs, which the MI3 II lacked, alongside RCA, a 3.5mm aux input and Bluetooth 5.0. Midiplus rates it at 70Hz to 20kHz, and the pair weighs just 3.31 kg, so it fits on a small desk.
Cons: No independent measurements have been published yet, so its tonal balance can’t be compared with ranked speakers. The MI3 II it replaces measured poorly on spinorama.org (a 0.99 preference score), and there is no data yet showing whether the V2 improves on it. The 70Hz rated low end means a subwoofer is needed for real bass, and it has no subwoofer output. It is mainly sold through Midiplus’s European and Asian distributors, with no US retailer yet.

Fluid Audio C35BT: $139 per pair Amazon eBay
Pros: Balanced TRS inputs, Bluetooth, front volume control and a headphone output make this inexpensive pair practical for a basic desktop setup. ASR’s measured -3dB point is about 78Hz, so it covers more upper bass than the shallowest-reaching mini speakers.
Cons: Preference scores of 2.57 standalone and 5.57 with an ideal subwoofer indicate that the limitations are not just missing bass. Listening-window narrow-band deviation of 0.555 and sound-power deviation of 0.657 show that response irregularities affect both direct and room-reflected sound. A subwoofer cannot correct those tonal problems, and the small drivers are not a basis for expecting high clean output.
