option 1 & 2 Dirac results.
I've also attached the Dirac before & after plot. Seem to be loosing a lot of output 25Hz-40Hz?
Compared to a target, yes. Compared to w/o Dirac, no.
Most all the measurements I have seen posted with Dirac are almost perfect for SPL, but I have no personal experience.
I presume Dirac cannot address all room effects. It did seem to improve the situation overall including, the bass range. I am surprised that the bass level is so high however. Was that close to a target response you set for Dirac?The 120 Hz timing we set may work okay for the other XO setting, but changes to XO slopes and Fo and even EQ will have some impact on the timing as well. Just looking at your series of results prior to Dirac I liked the way the XO at Fo = 80 Hz better than the 120 Hz we chose. With Dirac there was improvement as the Fo increased. This may be timing related. At some point you just need to pic a setting so you can listen to music.
