If the sketch is accurate then you are not placing the mic correctly. All of the mic positions need to be over the couch. In fact if you just 'moved' the whole lot in the direction of the red arrow I have marked on your sketch, that would be a better idea. This assumes you mainly are interested only in the one seat, where the mic positions are clustered.
Something more like this would be a more 'normal' mic layout pattern to try - yellow is the No1 position:
That assumes you want to calibrate for all seats along the couch.
Make sure the centre speaker is angled down towards the MLP.
I am assuming you are not interested in the other couch. It would be very difficult to get a good calibration for both couches anyway, so I’d concentrate on doing the best you can for the one couch and letting the other 'fall where it may'. All seats on the other couch are in a pretty bad position anyway wrt to imaging.
Hey guys, ok yes it is a sectional couldn't find one in the drawing program so just used 2 couches lol.... Only reason I had put the mic there was I was afraid if I put it on the actual couch it would screw up the readings....Center channel is angled downward toward main listening area & if you noticed I had left out my surrounds in the original drawing....I will take readings again tonite from your indicated locations & report back once I'm finished....
Thank you again!!!!
