Hi Dan--
Right. And by using the vst plug to pan all the channels around
randomly for 15-20 minutes, the test produced many possible mono
combinations with only one or two moments of very subtle
comb-filtering. The 50-240' spreads in the array portrayed major
timing differences in low frequecies from cars, trucks, motorcycles
and hi altitude jets, but rather than than creating imaging problems,
they formed a mesmerizing sense of the valley's reflections. I may
run into very different results down rhe road wth these set-ups, but
until then, I'm leaving worries about wide spaced omni's being
subject to major frequency phasing problems in the car. Rob D.
