A couple of months ago i got a new TV, 28" widescreen, pure flat. (This is the first expensive TV i have ever bought) Im getting into it all now, and surround sound is my next goal. Though being new to it all, i dont really know what i need to get it all working. I know i need an amp/receiver and a load of speakers, but i really dont know what all these OHMS, WATS, Hz, and "2-way", "3 way" do. Please help me to understand.
