Using dirac, I did acoustical measurements and the original curve versus DSP were very similar. It got a bit smoother. The original subwoofer curve looked normal.
These measurements were done in a room that had virtually no acoustical treatments other than corner bass traps it was a normal living room with furniture.
I wish I could attached the curve pictures but this forum don't allow photos to be attached I guess.
Would love to know if other people test their rooms before and after doing acoustical panels and how the curve changes. Lots of the acoustical treatments are voodoo science with results that may not do very much most of the time and actually served to dampen the room sound quality
