First of all, this time you quoted me something I deleted. Now..
If you don't lower your sub volume I guarantee Audyssey would trim you main's level by quite a bit. If that ends up being too low, like -10 then it is not good.
You absolutely need to find out the effect after level matching and report back to us asap.
I must agree, but even then at least you no longer find Audyssey mess up the sound, I mean flat + DEQ. Again DEQ is only effective at level below ref, I tried it and can confirm at high spl level DEQ is not quite audible.
Can't you just leave early to do it?
You should ask Dr./Prof kyriakakis, he's got the quali and is the founder, should be able to answer such simple question.
