You've lost me there.  Half a wavelength in feet is 1100/(2 f), so for
f=1kHz 1/2 a wavelength (which is a 180 degree phase shift) is only 6
inches or so.  Two mics 30 feet apart would be much much more than 180
degrees out of phase, right?  

So I don't see how it's possible to mix two mics more than a few inches
apart and preserve any kind of phase coherence.
