The sensitivity of microphone positioning in EQing systems varies from
microphone to microphone (pattern differences).  BUT this should hint
at some of the complex problems regarding room acoustics and loudspeaker
dispersion.

The amount of EQ changes as you move around the room since 1) you move
off-axis from the loudspeakers changing the amount of "uniform" acoustic
energy developed, and 2) you move into different room resonance areas.

I still believe that the answer is not in EQ but in the rest of the
system.  Spending hundreds of dollars in EQ and tens of dollars in
loudspeakers seems a bit lopsided and self defeating.  Taking time to
properly set up equipment and position speakers can prove to be quite
startling.
