The speech now is absolutely superb, its just amazing to listen to with all that shrillness gone.
I'm over the moon with the warmth I have from the Klipsch horns which are often criticized for being bright.
In my case it was getting the mic away from the back of the seat, 12" for me is the magic spot.
Plus I do think getting the top of the mic inline with the tweeter for at least for the 1st position helps.
My tweeters are a bit higher than the ears for my most important row (middle) out of three. The 1st position I lift the mic to the tweeter height then drop it to the ear height for the other 7 measurements.
Experimentation is important, don't give up.
Experimenting again with having the mains aimed more outward for better lateral soundstaging and hopefully still get flatter response - and avoid reflection.
My tweeters and ear-height are almost identical, so I use that as the setting point.
My latest try involved toeing-in the fronts firing just behind the center-spot. Chris from Audyssey, if I understood him correctly, said that measuring on-axis like this delivers flattest results. I've tried this before to flatten the response and it does work. The fact that speakers are firing to middle eliminates a lot of reflection. The result is a more bearable sound, flatter, and the perceived loudness is not nearly as high - as I can turn up rather high without it being overbearing. Sound was warmer as well, and still clear. Although the trade-off is that there is very little to no lateral sound-staging. Hence the sound is not nearly as engaging or exciting. I typically sit about 2 or 3 feet to the left, a bit off-axis, but it is all relative. It's tricky in certain rooms, since if I aim the mains more outward, I feel that shrillness more at the far left listening spot (far left meaning only 2 or 3 feet from center, and a mic-measuring location as well).
The closest offender is the left wall, and that could factor. There are times though when Audyssey tames the highs in that area and it ceases to be issue. Either way the soundstage needs to be wider than it is, despite the left wall. I notice that most here do not use toe-in for mains, or if there is it is minimal (like most movie theaters). My set-up is a bit on the shoe-box shape (one side of the apartment L-shaped room) so want to have the soundstage at optimal width. Hoping to get that right balance.
