What I have found is that most of the time there is always sounds coming from the surrounds, I only notice this when I stand right next them, the sound is very faint, as discussed, it is obviously recorded at a lower volume.
Well when I am watching a film from my couch, about 4 feet from the rears, I cannot hear any sound at all, only when specific sounds occur, flyovers, bullets whizzing etc.
What I would like to know is why bother recording any sounds there at all? If it is going to be so faint it is inaudible unless your ears are right next to them then why not save more money and have nothing there apart from flyovers, bullets whizzing.
To me it is an all or nothing thing
I am firmly in the continuous surround sound camp, I agree with them not being too loud to distract but if you are bothering to put something in them then the lowest levels should be continuously audible!
Maybe it is a bipole placement issue but I dont think so as I have had great help from Dale in finding the best placement for my bipoles which are now on the rear wall either side of the 3 seater couch. I tested loud surround scenes and placed the speakers on ladders moving them around and found that the side walls (the other bipole placement option) were really localised. So for big surround scenes on the rear wall they sound great but any other time not so much??
If it is not placement issues then I would have to say that it is more frustrating for the HC perfectionist to put sounds there because I just keep thinking I am missing these effects
