    Re: phase question

    Looks OK to me (never used Omni mic before, though).
    5ms SEEMs a bit long. You'd basically need to have nothing closer to your mic/DUT than about 6' (which would preclude 12' ceilings w/the measurements taken 6' off the floor) to be reflection-free.

      Is your driver on a very narrow baffle?
      You need to measure the drivers individually with phase then add them with phase so you can see the alignment.

            Better gate (for surfaces 4' away) would be 3.33ms, which limits data credibility to about 300Hz.
