Mirage Nanosat Impedance is 8 Ohms nominal / 4 Ohms minimum
They work fine so far but I haven't noticed a huge increase with sound quality. I'm using the stock wires which are so thin it's pathetic. Will try using some 14 gauge wire with banana plugs and see if that helps. It might also be the low power output of the wireless receiver in which case nothing will help. Have the rears maxed out at 5-6 for the settings. Also going to try my M&K M5 speakers which are 4 ohms and see how they work.
The Nanosat speakers sound great when connected to my Denon receiver.
