I'm getting my new system in place (Onkyo TX-SR607)... right now, it's 5.1 and when I get the two other speakers in the coming days, it'll be 7.1.
So my main question is this: which is better, having rear surround speakers or front height speakers? Note it isn't a huge room, maybe around 25-foot x 15-foot x 13-foot height (higher than usual). The main relax & watch area is probably only 15-foot x 15-foot, though.
Another thing that might make a difference: what movies use the height channel? I read "We Were Soldiers" was one of the first back in 2002, but I don't know if many movies use this channel to make it worth-while. And if there are many movies that do, what do I look for... Dolby what? What are the Dolby options, good - better - best? (TrueHD vs. Pro Logic II)
Lastly, in regards to the side surround speakers, I understand they should be about ear level when watching and equidistant from the viewer. But what if in this smallish room the speakers would be ear level, but 6-inches away from the ear... should the speakers go behind, or higher, or...?
My layman thoughts would be to use front height speakers and put the surround sound speakers up and behind the viewer about 6-inches, hopefully creating more depth from behind.
P.S. Dolby Laboratories is of great help, but of course they're going to brag about all their technologies. I'm not sure which is best, which to use, if TrueHD and Pro Logic IIz can be combined, etc.
