#43 Midiplus MI3 II: $139 per pair Discontinued eBay
Newer model: the Midiplus MI3 II V2, ranked higher, estimated 2.5/5.
Same family: the Midiplus MI5 II (larger bookshelf, rated 3/5).
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.
