Archaea and I did some more playing with the omni mic and positioning. Here are the results. These graphs are all taken at the same volume with no smoothing and the sub placements are not ideal. The F12 is placed in front of the couch between seating positions 1 and 2. Position one is the center of the couch, position 2 is to the left of the couch and next to the wall, Position 3 is to the right side of the couch and away from the wall. As you can see in the graph, the blue lines are the V1220s and the F12 while the red is just the v1220s. We found what we thought to be the best placement for the v1220s and then I moved the F12 around to see if it would help, and as you see in the graphs, I think it did help a little in flattening out the line.After listening to some movie clips and some music, it sounds drastically different. I'm hearing notes I didn't really hear before. There was a large lag at about 60 hz prior to moving stuff around and some songs sound a lot different with out that lull. Also, I am almost sure that I hear some sounds I didn't hear prior when watching the movie clips on the demo disc. I do believe I can specifically point out some sounds in the book of eli gun fight at the house. Also the THX clip sounds a lot smoother. So far I'm happy with the sound of this set up, but maybe not the positioning. I might play with re-arranging furniture, but I have a 3 piece sectional couch that is very very very large and if I turn it the other direction I'd only have about 6 inches between the wall and the couch thus making it difficult to get in to the area without climbing.
