Please don't spread out such news others less exeprienced may catch up with. My humble advise would be to look into the system set up for a bit of trouleshooting till the final result is achives "as intended". Agree?
Reducing HF boost by 5db is not placebo, especially when folks are complaining of 8db HF boosts after following the setup guides and FAQs to the letter. Novices can do thousands of calibrations to the letter, but if their rooms are large, they will never get to "as intended" because they are using a target curve designed for smaller rooms which by definition allow for more treble energy.
I agree tilting the mic is "unintended use," but so is using the default Audyssey target curve in a large room. Per my post above, quoted straight from the Audyssey Pro Kit user manual, Audyssey intends for a target curve with additional HF rolloff to be used in those large-room situations. Their instructions, not mine. Any disagreement you have on this point is disagreement with Chris and the Audyssey engineers, not me. As I'm sure you can appreciate, I follow their instructions/recommendations regarding room size and they work (imagine that)! And no, 3000+ cubic feet is far from church size. In fact, that's fairly common for an American multipurpose room with vaulted ceilings open to an additional room such as a kitchen, dining room, etc.
For folks in large rooms who cannot upgrade to Pro and are forced to use the incorrect target curve, how else do you recommend they attenuate their treble, even just temporarily, so they can at least evaluate Audyssey technology without fatigue-inducing brightness that is impossible to hear beyond?
Or do you still believe room size doesn't matter, that Audyssey itself is wrong on this point, and that all unexplainable HF boost is due to broken speakers?
We've had this discussion before, and my words nor Audyssey's own text is enough to convince you that room size matters. That is fine. We'll just have to agree to disagree on this, and move on, ok? I will continue to share this phenomenon with newbies, and you can continue to call it placebo and nonsense. That's what makes these forums so valuable...many alternative points of view. All is good! ;-)
