Hello again. My apologies for not coming back to this thread sooner. Thanks for all the responses!
My system consists of the 990 feeding 3 adcom amps which drives infinity kappa 8's ( front and rears) and an infinity kappa 7 for my center channel, low end is handled by 2 rythmik audio servo subs. I also have 10 2x4' by 3" thick sound absorption panels throut the room, most of them straddling the ceiling wall area ( the panels up front all have foil/kraft paper on the front). The room itself is small and odd shaped. It is 13' deep ( couch to tv) and 13.5' in length, 5' from the tv wall, the room length gradually increases to 16.5', so there is an 8' ( depth ) x 3' ( length ) area where you enter the room at. This makes it hard for me to use the room mode calculaters to find problem areas and I still haven't figured out how to use rew correctly.
Now with that aside, my front speakers are all very close to the same physical distance with the center being 7" closer. The rears are directly to the sides of the couch and the subs are upfront just behind the mains, in the corners. Before my 990 quit recognizing the microphone, 9 times out of 10, it would set all the fronts (including subs) at 12'. Occasionally it would set the left front and subs at 13'. For the rears, it sets the right 2' farther and the left 3' farther. I have always used the mic pointing straight up and have tried it at different heights using my camera tripod. I do calibrate at 0 and I also use a couple of different calibration discs to set spl.
I appreciate all the help! If this post doesn't make a lot of sense or seems like I am rambling on, I apologize, insomnia is a bitch! Thanks again, Brian.
