I just bought Pioneer VSX 527-K receiver and want to mach a speaker system. I am thinking about Magnat Interior 5001A 5.1 System. Are they compatible with each other? I don't have any idea about watts and ohms. Any comment or recommendation will be helpful. http://www.magnat.de/fileadmin/user_upload/Produkte/Interior_Sub_Sat_System_01.pdf http://www.pioneer.eu/eur/products/42/98/405/VSX-527-K/specs.htmlhttp://www.pioneer.eu/eur/products/42/98/405/VSX-527-K/specs.html Thank you!
