I have a rather large room but i have a bed, computer desk, couch, and tv all crammed into it. I am going to get the Onkyo Ht-s760 HTIAB system. My 1st problem is with my tv stand, my center speaker will have to be about 2 feet above my tv. So it will be about 3.5 feet above the listeners heads. Is this going to be a big problem? I could buy a new stand. if i had to. Also what is the minimum distance the front speakers should be apart? i can easy give them 5 feet apart. (2,5ft from the tv each. will that be a problem. Also same question with the rear surrounds. And last question how far should the rear center speaker be from the rear of the couch. The couch will only be about 4 feet from the tv. Should the rear then be 4 feet from the back? because that could be a problem.
