I have noticed that many online stores such as ecost, bestbuy, etc are providing Klipsch PM 4.1 with default input voltage rated 110v. Since I'm in a Asian country that has default voltage at 230v, so may I know if I purchased one of these online store Klipsch PM 4.1 with 110v, can I connect them with problem to those voltage transformer that is easily available & it has many input voltage from 100v to 240v. So, would it be able to support the KLipsch 4.1 without overloading or even pose potential voltage issue if this is constantly connected with these universal transformer? Otherwise, pls advise me what solutions I can get in order to fully enjoy my fream of owning one of these Klipsch 4.1? My country in Singapore doesn't have any more of these Klipsch Promedias 4.1, and I really hope that someone with technical knowledge of this power input voltage difference and it's feasibility or etc, can pls kindly provide me some solutions. Thank you very much.
