In that case, I would put your No 1 mic position at ear level where you usually sit, and cluster the remaining mic positions around the MLP. If you care about the seats either side of you, then spread the mic positions out a little to encompass them too. If you don't care at all about the rear row, ignore it totally. If you care a little but about it, maybe put two mic positions there. Just experiment. In my HT I am the only one who cares about SQ, so I cluster all my positions around the MLP, roughly 1 foot apart.
Cool. I will do some experimenting. I probably will only have time to run all measurement positions once today. I can only throw the wife and three year old out of the house for a bit. I'll probably do a few in the back row, see how it sounds, if I don't like it I'll probably re-run it again during the week concentrating on the MLP.
