Hello,

So I received my two new ML Vistas yesterday, fresh out of the box. I plugged them into my Onkyo HT-RC260 Receiver and they sound like they have 0 treble. What's worse is one of the subwoofers doesn't put out sound at all.

In Japan, we receive 100V, 50Hz out of the wall outlet, but I have a converter. It's putting out 120V, 60Hz just fine. My receiver and both speakers are plugged into it.

Lastly, if I unplug the power to the speakers, the treble increases dramatically for about 20 minutes and then slowly starts to fade off again.

What would you do?
 
So the speakers are 50Hz or 60Hz models. They will not power up if the frequency is different from the design frequency.
