You can also pick the reference to get some HF roll off. Most main speakers don't get to look pretty at the high and low ends unless you use smoothing as Shady mentioned. You can now see why changing well designed amps won't make much audible difference. You can now add an external 300WPC ATI amp, and the two frequency response curves will just overlap to look like one. At comfortable listening level, the distortion curves would also look very similar. Moving your mic by even 6 inches will, however, result in different curve.I currently have an Audyssey curve loaded in my avr right now that I did not use the the app to take (subs trimmed -10, upper frequencies boosted a little more) and did some sweeps. A couple sub sweeps and a couple with both L/R main speakers by themselves, DEQ on and DEQ off for both sets of sweeps.

I overlayed the sub with my main speakers in both of these. This one is with DEQ on.

This one is with DEQ off. What am I looking at here? To my untrained eye my main speakers are a real mess!
I'm going to upload the last app file I measured using the app and do the same sweeps. I wanna see what it comes up with. I'm almost positive they'll be quite a bit different. Everything is equal for both files. The only difference is one was taken using the app and the other without. Again, this set of sweeps is based on a curve not measured by the app.
