Hi Sidney,
I don't know much about the European market so I cant be much help, but these is no reason why the stuff you are looking at wont work. I personally wouldn't go through the trouble of running speakers to the kitchen and bathroom with all of the easier bluetooth options available, but to each his own.
Since you are looking at smaller speakers also consider just doing all SVS, or look in KEF's offerings as well. Other then that I'm not sure what you have available over seas..
Best of luck to you.
