Just wanted to know from others here that when it comes to speaker matching, is my information correct that the most cruical is the front L/R and Centre speakers should be as close a match as possible? And that the rear speakers when it comes to speaker matching is not as crucial? For movies anyway. (I am currently only using 5.1 setup, and for my room size, it is not worth the bother to even contemplate doing a 7.1 setup, considering I don't own Blue Ray, and may not for some time. I am still satisfied with my existing DVD collection. I am always hearing many sides when it comes to this. I am certain there may be others here that probably have their fronts and rears as a different brands, and yet is still acceptable?
