the Dolby page shows the alternative placement of surrounds putting them slightly behind the listener, aimed straight up at the ceiling (raised slightly off the ground). I did a search and saw it stated this can lead to nice dispersion. but my search didn't come across any posts saying they've done this and are pleased with the results. I know this method is probably not the Best, but it might be an interesting option for my limited space needs. and allow for a larger surround (paradigm Atom). I figure if Dolby lists it, it must have some merit???? thanks.
