This purchase was accompanied by a return of 10 (by sending bills, bar code and RIB within which I greatly respected). He just told myself that it could not respond to my request for lack of original barcode of transmission, although this ALL ORIGINAL documents were transmitted. Scam? Comment evaluation of these speakers, left on a site other than Amazon recommended to perform the registered post ... Well, well! Regarding speakers, the sound is ok but, at home, they often emit a brief sound (OCD) unpleasant, remaining after remade connections. They are, therefore, not currently in use.
