The part about levels doesn't make sense. Mic orientation relative to the speakers would only Impact high frequencies, but levels aren't really impacted by that.Here is the link with the best Atmos setup (possibly) and it states the Audyssey mic is not the best for setting the Atmos levels per its shape and speakers firing direct in to mic. + 2 to +4db on all atmos speakers works very well.Thanks, zebidou. Even though you didn't aim your answer to me, I think your answer would help me, too. Once I get back my Denon from Upgradeville I will try upping the volume level on the front heights by a couple of decibels before I try to pull off something as exotic as an array.Ok for height speakers is it now safe to say that most people bump them up by a minimum of 2db so that they sound the best, is it possible that using Audyssey XT32 that as the speaker is firing directly in to the mic that it sets the height speakers at a lower trim level i am pretty sure this is the case, i was trying an Audyssey calibration with the mic tilted at a 25 degree angle but i feel this gave mixed results to the base level speakers ? i know height makes a big impact on calibration, i had my front l/r raised off the floor by 1.5ft and my xover was being set at 120hz now i have them on floor xover is set at 60hz so maybe speakers firing directly into mic gives a false level reading
Rather the more sensible explanation is that it's just a preference for people who like to hear more overhead action.
