Hi johnp98,
I'm interested in your results, but I can't read the numbers of the vertical scale of your graphs. How many dB are there ?

Hummm... I also was expecting a larger response. I wonder if it is having a hard time with the subwoofer? Should I just measure the speakers with no sub? Or am I looking at the wrong thing? I feel quite proficient with measurements and the frequency response (and waterfalls etc), but the impulse and step responses I am not too sure how they are typically displayed and with what settings. Curious why there is not a more significant response. Thoughts?
It is from 100-50dB, so each line is 5db.Hi johnp98,

Yeah it was based on the MultiEQ older version which is the only version that I have access to.There are 2 pages now so I may have missed some important facts. Is the Audyssey one based on the old XT version?
Using XT32 SubEQHT, it did a much better job for me, based on my REW graphs for FL+FR+two different SVS subs.

I was using it prior to getting a measurement mic and learning REW and as you can see from the graphs in the first post I was shocked to see how horrible of a job it was doing.
I certainly hope the new versions are significantly better and it sounds like that is the case but I think it's important for people to realize that the old versions should not be trusted and I would not trust the new versions unless I had a mic and REW to compare pre and post.
Playing around with the AVR EQ settings a bit more, I found that you can manually change the 9 preset filters of 63hz, 125hz, 250hz, 500hz, 1k hz, 2k hz, 4k hz, 8k hz, 16k hz yourself. I am not sure what the Q value on these filters are, but it does seem quite wide and based on moving mic measurements an EQ of seemed to be the best. After playing around using these filters (125hz -1(L) -4 (R), 250hz +2, 500hz +1 , 4k +1 8k = -2) I got:
Hopefully this is just because I have an older version, but it was scary how bad vanilla Audyssey made it, and if I did not have a measurement mic then I would be in the dark with how to improve on what Audyssey gave me… wrong crossovers, wrong delays, and wrong EQ. Scary stuff.
If you go into manual mode in my receiver (Marantz SR7002) then it lets you manually change the preset filters. So its semi useful, but nothing compared to new versions of Audyssey or computer based Equalizer APO and what you can do with REW.I do have questions of this, what preset filters are you referring to? Are you still talking about the SR7002 and Audyssey? As far as I know Audyssey XT does not have any such preset filters, its auto only. It also do not have the "Q" to sorry about, unlike YPAO and I think (AARC too) that are based on IIR filters.
