Hi Marv!

And they didn't have bass traps all over the place? Sheeshm with 12 dual

That's my prefered method to set up a system as well, when there is
enough time. I did a large church job once that I had a lot of time to
fine tune the system, and when I added the Ivie test set on it there was
only minor changes in a couple of bands when tuned to some of my
personal favorite material.
I like to mold the system as needed over a few hours before actually
starting to rely on the RTA, Unfortunately, we often don't get the
luxury of testing ourselves at the same time we bring a sound system to
life and usually have to try for a flat curve with the greatest of
speed and not self test ourselves at the same time the system gets
tested. It is the final stages of system design and construction though,
and time passes all to quicky on this gratifying, yet occasionally
frustrating part of sound system installations.
