I've some input voltage issue regarding these Kilpsch speakers or even other speakers ordered online. So, can anyone tells me whether if I'm able to connect the voltage input of those USA online stores selling of Kilpsch 4.1 which I think has input voltage 110v, but mine country is using 230v, so, will there be any problem if I just connect such power connector with a Universal Adapter like those traveller's types which has all sorts of different socket's pin head and switch-able input voltage from 110-230v? I'm worried only about the woofer not able to get the desired voltage if it's connected thru those universal adapter as I've heard there's a "amp" within it, so or vice versa, it might even be overloaded and burst the speakers? or will it cause overload for the prolonged use of the universal adapter? Thank you.
