I have what one might consider a moderately okay home theater. Half-way mid range receiver, Onkyo TX-700, a couple yester-year liquid cooled main speakers, a 12" velodyne sub. But my center and rear surrounds are radio shack cheapies. I have been doing all sorts of research and reading the past couple of weeks and was wondering if anyone could point me in the right direction as to what to look for in a center speaker and the rear speakers. I really am most interested in the center speaker for now. Have between $400.00 and $600.00 to play with and hoping that is enough to get something I would be happy with. Any help and advice would be much appreciated. Or just point me somewhere to read up on some more info. Thanks !!
