美国110V的PC speaker， 能带回国吗？大侠请进

刚买了一个logictech 5.1 ch X-540 PC speaker, like it very much, want to bring back to china.

But it use the 110V60hz, I want to buy a voltage transformer from 220 to 110. But I still have a
concern about the 60hZ.

Does the amplifier in Speaker use the 60hz to drive the circuitry?, does 50Hz in China has some impact on that PC speaker?

Thanks
