I am looking for a 5.1 audio system + receiver, on a budget around $900, for a 5m x 4m x 2.7m living room, 220V/50Hz, Romania. My heart is now pretty much set on the Energy RC-Micro speakers, based on the good reviews they get. The problem is that I can't find them in Romania, and the European stores that carry them have ridiculous prices (599 EUR, as opposed to $399 in the US). So, as I have the option to get them shipped cheaply from the US through a friend, I thought I would go with the following setup: - A/V Receiver - a dual-voltage Denon/Yamaha/Onkyo receiver, to be bought from the US (~$400) - Energy RC Micro 5 Pack 5ch Home Theater System, to be bought from US (Amazon, $190) - Energy ESW-C8 Subwoofer, to be bought from EU (Akustic-center, EUR 250) Can you please tell me: 1. Is there any problem with using the US version of the RC Micro speakers in Europe (220V/50Hz)? I am thinking no, as they would go into the the 220V receiver I am also getting, but I am a newbie and I want to get a confirmation on everything... 2. Is there any better Energy subwoofer that you would recommend for this setup, for roughly the same budget? 3. What minimum features should I be looking for in a receiver to make sure it's not "the weakest link" in this setup? Thank you all very much, looking forward to your feedback
