Exactly what I have done, I use audyssey flat, no DEQ turn sub up +6Db. I have done over 200 calibrations at least, have a $500 mic stand. I even have a screw in rear wall so I can attach a tape measure to go get Mic exatly where my ears are. I then put laser on center channel exactly in middle of tweeter and positing mic so laser is on mic.
When doing calibration I turn off TV, HVAC, lights ect. No noise what so ever. My positions as of now are 2ft apart in the following since I have 3 seats, but adding another row this week
Then move mic in front of those 3 spots 18"
Then 2 measurements 35% in for surrounds in rear.
Last night I turned it all off and went into tone settings and set the following
It sounds world's better, not even in.same league. I heard detail in "tron" that I have never heard, the bass was much tighter. 5 people said with it on the system seemed muffled, all preferred off and I have to agree.
Does it sound good with audyssey flat? It certainly does, can it sound better....god yes!
