I was curious how moving the Position from the cap to edge affected the IR (4X12 Friedman V30 with a Condenser) so I collected some data and made this...
The graph shows how the IR sounds as we move from the cap to the edge of the speaker comparatively to the cap position.
The graph is smoothed in psychoacoustics
"Psychoacoustic smoothing uses 1/3 octave below 100Hz, 1/6 octave above 1 kHz and varies from 1/3 octave to 1/6 octave between 100 Hz and 1 kHz. It also applies more weighting to peaks by using a cubic mean (cube root of the average of the cubed values) to produce a plot that more closely corresponds to the perceived frequency response"

Better to use ears not eyes while adjusting this parameter but I thought I'd share this just to help make an informed decision graphically and aurally!
(atleast for this specific speaker/mic combo, 4X12 Friedman V30 with a Condenser)
