#20 Midiplus MI3 II: $139/pair eBay
Pros: Tiny powered monitors with Bluetooth, RCA and auxiliary inputs plus high-frequency adjustment. The local snapshot reaches 3.45 with a subwoofer and 66Hz measured extension.
Cons: A very low 0.60 raw preference score indicates conspicuous tonal flaws, while 3-inch woofers and 98dB maximum SPL restrict output. One amplified speaker drives the second, and there are no balanced inputs.
How it compares: Just above it: M-Audio BX3 - $50 cheaper. Just below it: Presonus Eris E3.5 2nd Gen - $39 cheaper.
