Is PSW110 110 to 240 volt?

Hi,

I'm moving overseas, and I would love to purchase a subwoofer before moving because any electronics are much more expensive outside of America for the most part.

I called Polk and was told that the psw line including the 110 was only a 110volt system. However, I have found a few photos online which show the back of the subwoofer and it states that it accepts 110-240 volts and 50/60 hertz. Which is it? Can I use this receiver overseas, or if I buy it in the USA will it only work in the USA? Can someone take a look at the back of their sub for me?

Thank you in advance for any help anybody can offer. This is my first post here.
