Dana, it's correct that the Audyssey room equalization settings aren't subject to be being manually "tweaked"(this doesn't refer to changing crossover frequencies or speaker distances). Dr. Kyriakakis of Audyssey has been asked questions relating to this several times and has
made clear that the provision in some receivers for making manual equalization settings is not part of Audyssey. They provide for just a few frequencies that Audyssey has adjusted to be "copied" into a manual equalizer where they could be changed. Dr. Kyriakakis has termed this a "crude approximation" of what Audyssey has done, involving many more adjustments in the frequency and time realms, and believes that this opportunity shouldn't be included by the receiver manufacturer. So yes, the choice is either the Audyssey results or the manual equalizer which can't be used to "tweak"(misadjust)the Audyssey equalization results.
This makes sense to me, although it apparently frustrates some who have a belief(naive in my view)that they can do better if they could modify the results with a relatively crude manual equalizer.
