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.

Midiplus MI3 II: $139 per pair Discontinued eBay
Newer model: the Midiplus MI3 II V2. It’s likely to perform similarly, though we can’t confirm that yet.
Pros: Compact cabinets, Bluetooth, analog inputs and high-frequency adjustment can suit a basic desktop system. The measured -3dB point is about 67Hz, so missing bass is not its only differentiator from other tiny speakers.
Cons: Preference scores of 0.99 standalone and 3.84 with an ideal subwoofer are poor. High narrow-band deviations on-axis (0.938) and across the listening window (0.852) indicate pronounced response irregularities that can color voices and instruments. The fairly flat overall trend does not mean the response itself is smooth. A subwoofer or simple treble adjustment cannot resolve all of these problems. Discontinued.
