My parents are setting up a 6.1 HT and when I went to check out the progress this weekend I noticed the company installed the rear surrounds and rear center in the ceiling. I don't have the model number but the speakers are MK inwall speakers. I know the correct placement per Dolby is parallel witht he listening point and slightly above. Simple question is how much do you sacrifice with this positioning for asthetic reasons? One good thing though they didn't let me build them a Sono but they did buy a SVS so that was a plus.
