Somewhere I should mention that I am using the OmmiMic DVD to help me. In addition to doing basic frequency response charting, I used it to precisely configure the relative speaker distance which was oddly quite wrong in the Anthem settings. I mean, of course I started by measuring distances with a ruler and put that in with half-foot accuracy but the timings were not correct for the surrounds vs. the front channels. Off by a good two feet or so ( i.e. 2 mSec). When you introduce DSP to one channel but not others like I do by using it in the Center and Sub only you also have to deal with extra delays in processing there.
Of course in a motion picture auditorium, there is only 1 seat in the house where you achieve such absolute precision in arrival times, but hey, audiophiles are nothing if not fussy.
Using a combination of the OmniMic DVD and miniDSP’s very precise delay settings I was able to get perfect delay matching.
