That's good to know. I won't touch that distance.
I reran last night using a full 8 measuring points and again there is a massive peak in the high end. It's +10dB at about 8kHz and that peak does not tail off much by 20kHz. It's in all of the speaker graphs.
This is making me suspect that my microphone is faulty. I'm using the Audyssey mic that came with the 5308A upgrade.
I've ordered the Pro kit since I really need to get more insight into what is going on. Until then, the best sounding option is to leave Audyssey off, which is not the way it should be, of course. Even Audyssey flat had a giant peak at around 8K. BTW, Audyssey set to off with the accoustic treatment we've added actually sounds great. It sounds nice and even with no bass ringing.
With Audyssey enabled, the audible result is that any amount of hiss in a recording becomes very apparent. So I know my tweeters are working and I seriously doubt my ears have become more sensitive to high frequencies as I've gotten older (unfortunately works the opposite way).
So, I'm down to either a mic defect or a processing problem in the 5308A. I'm doubting the processing problem since it does produce a coherent graph for each speaker. Anyway, I'll know more when the pro kit gets here and I get the license from Audyssey..
